Scenarios: 2010 hurricanes may wreak havoc on oil spill, Haiti

(Reuters) – The Carib Indian god of evil, Hurican, gave its name to the word “hurricane,” and the 2010 hurricane season that started on Tuesday is shaping up to be a monster of potential malignancy.

U.S. | Green Business | Hot Stocks | Gulf Oil Spill

Hurricanes are feared every year because of the whirling destruction they inflict on human life, property, crops and industry from the Caribbean to the U.S. southeast Atlantic coast and the Gulf of Mexico. The annual hurricane season begins on June 1 and runs through November 30.

But this year experts fear destructive storms could unleash additional havoc on two of the biggest disasters — one natural, the other man-made — ever experienced in the Western hemisphere in recent years, the January 12 Haitian earthquake and the six-week-old BP oil spill in the Gulf of Mexico.

“HELL OF A YEAR”

The risk of hurricanes complicating the catastrophic situations already caused by these two disasters is increased because U.S. forecasters are predicting an extreme hurricane season with an above average number of powerful storms.

“This looks like a hell of a year,” says hurricane forecast pioneer William Gray, who founded Colorado State University’s respected storm research team.

The National Oceanic and Atmospheric Administration has predicted one of the more active seasons on record, forecasting 14 to 23 named storms, with eight to 14 developing into hurricanes, nearly matching 2005′s record of 15. Three to seven of those could be major Category 3 or above hurricanes, with winds of more than 110 miles per hour (177 km per hour).

The Gulf Coast may see a repeat of the 2005 season when a record 28 storms formed, which killed nearly 4,000 people and caused an estimated $130 billion in total damages. The list included Hurricane Katrina, which devastated New Orleans.

HURRICANE + OIL SPILL = “HORRIBLE MESS”

Some Gulf Coast officials are already equating the environmental and economic impact of the out-of-control oil spill to a Category 5 hurricane — with lasting effects on businesses, individual livelihoods and natural habitats.

But a hurricane churning through the oil spill zone would disrupt slick cleanup operations and ongoing attempts to control the leaking undersea well — including one currently seeking to place a containment cap over the leak in a bid to capture most of the escaping oil and pump it to a surface vessel. Other ships and surface platforms are drilling a relief well expected to be completed only in August.

“Obviously, the new concern we have is that we are entering hurricane season,” top White House energy adviser Carol Browner told CNN. She said spill response vessels might have to stop working in a hurricane, which would further delay the efforts.

Even more horrendous, forecasters warn, are the prospects of a storm surge — an abnormal rise in sea level created by a hurricane — whipping spilled oil and used chemical dispersants much further ashore onto beaches, vegetation and even homes.

“The foul mix would ride inland on top of the surge, potentially fouling residential areas and hundreds of square miles (kilometers) of sensitive ecosystems with the toxic stew,” Jeff Masters of Weather Underground wrote in a recent blog. But he added a hurricane could dilute the mix with sea water, and wash much of it off the vegetation with rain.

Nonetheless, the thought of a hurricane blasting sticky oil inland is high in the minds of many Gulf Coast residents.

“Even a small, small storm would dump the Gulf into our area which would be more oil than water probably,” said Ann Griffice, a resident of Empire, Louisiana.

Frank Gill, president of the National Audubon Society, sees a risk of a storm-driven surge crashing into the Gulf Coast, “leaving millions of nesting birds vulnerable to oil washing onto breeding islands, beaches, sand flats and mudflats, and seeping into wetlands, and coastal terrestrial habitats.”

HAITI HOMELESS IN HARM’S WAY

In disaster-prone Haiti, nearly five months after a catastrophic earthquake that killed some 300,000 people — according to government estimates — more than 1.5 million quake survivors are still living in over 1,000 fragile, crowded tent camps in and around the wrecked capital Port-au-Prince.

Relief workers are bracing for the extra-active hurricane season and hoping against hope that it does not unleash the kind of flooding and landslides which have killed thousands of Haitians in the past — even without the kind of vulnerable situation that the poor Caribbean country now finds itself in.

“This is a prospect that we’re certainly not happy about … We don’t want to have a secondary disaster on our hands,” Julie Schindall, international media officer of Oxfam, said.

An evaluation of 28 camp sites where Oxfam works has concluded that thousands of survivors are vulnerable to landslides and flooding due to hurricanes, the organization said. It called on the Haitian government to urgently implement a public communications campaign to inform people about risks.

Extreme overcrowding, little natural drainage and weak land structure were major problems highlighted in the Oxfam survey. Relief groups were working to improve drainage and help the communities to place sandbags around their shelters.

“When you see someone living under a plastic sheet, on a dirt floor, imagine that under a foot of water, Schindall told Reuters, saying there were concerns too that water pooling in the camps would increase the risk of epidemics.

The government and its aid partners have moved some survivors to more secure sites and are clearing storm drains.

U.S. relief and development group Food for the Poor said housing remained one of the biggest needs. “It takes only a few inches of rain to put lives in danger because that’s all that is needed to produce flooding and mudslides,” it said.

In 2004, Hurricane Jeanne killed over 3,000 Haitians. In 2008, hurricanes Gustav, Hanna and Ike killed some 1,000, destroyed 20,000 homes and wiped out 70 percent of crops.

Top U.S. hurricane forecaster sees “hell of a year”

The threat of more hurricanes than usual in the Atlantic has risen in the last month, and it promises to be “a hell of a year,” a leading U.S. forecaster said Wednesday.

William Gray, the hurricane forecast pioneer who founded Colorado State University’s respected storm research team, said CSU would ramp up its predictions for the 2010 Atlantic hurricane season in a report due out on June 2.

“The numbers are going to go up quite high,” Gray said. “This looks like a hell of a year.”

Gray, who spoke on the sidelines of a regional hurricane conference, declined to specify the number of storms CSU will forecast in its outlook next week.

In its previous forecast, released on April 7, CSU had projected the season would produce an above-average eight hurricanes, four of which could be major.

Major hurricanes pack powerful sustained winds of at least 111 miles per hour (178 km per hour) and can go up to more than 155 mph which would be a Category 5 hurricane on the Saffir-Simpson Scale.

For instance, with winds blowing at 111 to 130 mph, Hurricane Katrina ranked as a Category 3 hurricane when it hit New Orleans in late August 2005. Katrina caused a catastrophic failure of the New Orleans levee system and is considered the costliest hurricane, and one of the five deadliest, in the history of the United States.

Indeed, 2005 went down as a record-breaking hurricane season after Hurricane Wilma hit in October. It was the 22nd storm, 13th hurricane, sixth major hurricane, and fourth Category 5 hurricane. Wilma’s most destructive effects were felt in the Yucatan Peninsula of Mexico, Cuba and Florida. It ranks as the fourth costliest storm in U.S. history.

In its April 7 forecast, CSU also said the six-month season beginning on June 1 would likely produce 15 named tropical storms.

An average Atlantic season has about 10 tropical storms, of which six become hurricanes. Tropical storms typically pack winds of 39 to 73 mph.

Gray and Phil Klotzbach, lead forecaster with the Colorado State team, both told Reuters that forecast models showing a recent shift in wind patterns and warm tropical Atlantic waters had reinforced the likelihood that a busy hurricane season was on its way.

“Everything is setting up as a very active season,” Gray said.

Microbes aren”t accelerating global warming as expected

London, April 17 (ANI): Soil microbes are producing less atmospheric carbon dioxide than scientists expected, a new American research has found.

The findings of the study, conducted by researchers at the University of California at Irvine, Colorado State University and Yale University, have appeared in a paper published on-line this week in the journal Nature Geoscience.

Saran Twombly, program director in NSF”s Division of Environmental Biology, said: “Microbes continually surprise us in the diverse ways they respond to environmental conditions.

“Microbes play a central role in ecological processes,” said Twombly, “and their responses change our understanding of natural communities in fundamental ways.”

Conventional scientific wisdom holds that even a few degrees of human-caused climate warming will shift fungi and bacteria that consume soil-based carbon into overdrive, and that their growth will accelerate the release of carbon dioxide into the atmosphere.

But a research team led by ecologist Steve Allison of UC Irvine took a closer look, and found something different.

While microbial soil decomposition, and resulting carbon dioxide emissions, increase initially, microbes eventually overheat and grow more slowly.

As their numbers decline, they release decreasing amounts of climate-warming greenhouse gases.

Allison said: “Microbes are the engines that drive carbon cycling in soils.

“In a balanced environment, plants store carbon in the soil and microbes use that carbon to grow. Enzymes produced by microbes convert soil carbon into atmospheric carbon dioxide.”

A previous study by Mark Bradford of Yale and Matthew Wallenstein of Colorado State found that microbes became less efficient at decomposing soil carbon after several years of experimental warming.

They asked Allison to develop a computer model to test how adaptation of microbes to climate change might affect the carbon cycle.

Bradford said: “The issue we have in predicting whether soil carbon loss will accelerate climate warming is that the microbial processes causing this loss are poorly understood.

“More research in this area will help reduce uncertainties in climate prediction.”

In the resulting computer model, microbes became less efficient at converting their carbon food source into biomass as climate warmed.

In short, the microbes were not well adapted to a warmer climate. As their growth slowed, so did enzyme production.

Allison said: “When we developed a model based on the actual biology of soil microbes, we found that soil carbon may not be lost to the atmosphere as the climate warms.

“Conventional ecosystem models that didn”t include enzymes did not make the same predictions.”

The next steps include studying more microbes and more ecosystems.

Microbes from a Massachusetts forest inspired this study, then Allison began collecting soil samples from California, Alaska, Maine and Costa Rica.

“Nearly one-third of all soil-based carbon is sequestered in permafrost or Arctic regions, which might respond differently to warming,” said Wallenstein, who is researching sites in Greenland and Alaska.

Allison said: “We need to develop more models to include microbe diversity.

“But the general principle that”s important in our model is the decline of carbon dioxide production after an initial increase.” (ANI)

U.S. forecaster sees increased 2010 hurricane threat

The 2010 Atlantic hurricane season will produce an above-average eight hurricanes, four of them major, posing a heightened threat to the U.S. coastline, the Colorado State University hurricane forecasting team predicted on Wednesday.

In its second forecast in four months for the 2010 season, the leading storm research team founded by hurricane forecast pioneer William Gray said the six-month season beginning on June 1 would likely see 15 named tropical storms.

The team forecast a 69 percent chance of at least one major hurricane making landfall on the U.S. coastline in 2010, compared with a long-term average probability of 52 percent.

Major hurricanes pack powerful sustained winds of at least 111 miles per hour (178 km per hour).

For the Gulf Coast, from the Florida Panhandle west to Brownsville, Texas, including the Gulf of Mexico oil patch, the probability of a major hurricane making landfall was seen at 44 percent versus a long-term average of 30 percent, the Colorado State University team said.

“While patterns may change before the start of the hurricane season, we believe current conditions warrant concern for an above-average season,” Gray said in a statement.

An average Atlantic season has about 10 tropical storms, of which six become hurricanes.

The Colorado State University team also predicted a 58 percent chance of a major hurricane tracking into the Caribbean, where Haiti is vulnerable after a devastating Jan. 12 earthquake that left more than a million people homeless.

‘EXTREME’ SEASON FEARED

The earlier forecast in December by Gray’s team had already predicted an “above-average” season producing 11 to 16 tropical storms, including six to eight hurricanes. It had said three to five of next year’s storms would become “major” hurricanes of Category 3 or higher on the Saffir-Simpson intensity scale.

Another forecaster, AccuWeather.com, last month also forecast a potentially “extreme” hurricane season this year, with “above-normal threats” to the U.S. coastline.

AccuWeather said five hurricanes, two or three of them major, were expected to strike the U.S. coast, forming out of an expected 16 to 18 tropical storms, almost all of them in the western Atlantic or Gulf of Mexico.

The 2009 season ended Nov. 30 had only nine storms, including three hurricanes, and was the quietest since 1997 due in part to El Nino, the eastern Pacific warm water phenomenon that tends to suppress Atlantic hurricanes.

But Phil Klotzbach, lead forecaster with the Colorado State team — whose research is followed closely by energy and commodity markets — said El Nino was expected to dissipate fully by the start of this year’s storm season.

“The dissipating El Nino, along with the expected anomalously warm Atlantic ocean sea surface temperatures, will lead to favorable dynamic and thermodynamic conditions for hurricane formation and intensification,” said Klotzbach.

The Colorado State University team has repeatedly cautioned that extended-range forecasts for hurricane activity are imprecise and can often miss the mark.

The university team originally expected the 2009 season to produce 14 tropical cyclones, of which seven would become hurricanes. But the season, which ended on Nov. 30 and was the quietest since 1997, had only nine storms, including three hurricanes.

Seismic test of 7-story building will be world’s largest quake simulation on wood

Washington, July 10 (ANI): A team of researchers is all set to perform the largest earthquake simulation ever attempted on a wooden structure, with a seven-story building planned to be tested on the world’s largest shake table in Japan.

A multi-university team, led by Colorado State University, has placed a seven-story building – loaded with sensing equipment and video cameras – on a massive shake table, and will expose the building to the force of an earthquake that hits once every 2,500 years.

The experiment, which will be Webcast live on Tuesday, July 14, should yield critical data and insight on how to make wooden structures stronger and better able to withstand major earthquakes.

“Right now, wood can’t compete with steel and concrete as building materials for mid-rise buildings, partly because we don’t have a good understanding of how taller wood-framed structures will perform in a strong earthquake,” said Michael Symans, associate professor in Rensselaer’s Department of Civil and Environmental Engineering.

“With this shaking table test, we’ll be collecting data that will help us to further the development of design approaches for such structures, which is one of the major goals of the project,” he added.

The shake table experiment will offer researchers a chance to better understand how wood reacts in an earthquake, and the resulting data could lead to the advancement of engineering techniques for mitigating earthquake damage.

“As the ground shakes, the energy that goes into a building needs to flow somewhere,” Symans said.

Typically, a large portion of this energy is spent moving – and damaging – the building.

There are proven engineering techniques for absorbing or displacing some of this energy in order to minimize damage, but the technology for doing so has not yet been thoroughly evaluated for wooden structures.

Next week’s shake should produce sufficient data to allow the research team to develop accurate computer models of mid-rise wood buildings, which can subsequently be used to advance and validate some of these seismic protection techniques.

“The system allows a significant portion of the wood-frame displacement to be transferred to the dampers where the energy can be harmlessly dissipated,” Symans said.

“With dampers in place, we have a better ability to predict how a structure will react to and perform during an earthquake,” he added. (ANI)

Book debunks the myth that there are only two sexes

London, July 6 (ANI): A Colorado State University expert has debunked the myth that there are only two sexes.

Gerald Callahan, an associate professor of immunology and the public understanding of science at Colorado State University, writes in ‘Between XX and XY: Intersexuality and the myth of two sexes’ that the stereotypical view of two sexes – me Tarzan, you Jane – limits people’s understanding and appreciation of their own biology.

He argues that there is a range of sexual characteristics that stretches from the testosterone-inflated Tarzan to the womanly “perfection” of a stereotypical Jane, and all the variations that lie in between.

“In truth, we are all intersex,” New Scientist magazine quoted him as having written in the book.

The standard model of human development is built on 46 chromosomes, including two that determine sex: XX for female, XY for male.

Callahan, however, insists that not everyone ends up 46XX or 46XY.

According to him, variations in sperm or egg, in the mixing of cells from mother and father and in the cell division that follows can all stir the genetic soup into alternative outcomes.

“(The possibilities) are as grand and as varietal as the fragrances of flowers: 45X; 47XXX; 48XXXX; 49XXXXX; 47XYY; 47XXY; 48XXXY; 49XXXXY; and 49XXXYY,” he writes.

While geneticists are familiar with such variations, says Callahan, the general public is still stuck in a black and white, XX/XY world.

Callahan’s book is spent exploring the understanding of intersexuality, from the physicians of ancient Greece to today’s neuroendocrinologists.

He also weaves in the stories of people who live in the stretch between the classic male and female endpoints. (ANI)

Northern spotted owl loses genetic diversity with drop in numbers

Washington, June 28 (ANI): A new study has determined that with a drop in its numbers, the northern spotted owl has also lost genetic diversity.

The northern spotted owl has been a controversial conservation icon for years, ever since large swaths of old-growth forest in the Pacific Northwest were set aside to protect the threatened bird 15 years ago.
That decision angered logging companies and forced them to take a financial hit. Still, despite the extra protection, spotted owl populations have continued to decline.

Now, according to a report in Discovery News, a new study helps explain why: With a drop in numbers, the birds have lost genetic diversity.

In addition to habitat loss and competition from other owl species, this type of genetic bottleneck makes the species more vulnerable to inbreeding problems and less resilient in the face of disease, climate change, and other challenges.

“It provides additional evidence that spotted owls are not doing great right now,” said Chris Funk, a population geneticist at Colorado State University in Fort Collins.
“It also points out that we might have to think about another threat to spotted owls, which is the threat from loss of genetic variation,” he added.

Northern spotted owls live in old-growth forests throughout the Pacific Northwest, from southwest British Columbia to northwest California.

The owls have brown feathers with white spots, deep dark eyes, and a nearly 4-foot wingspan. Their distinctive hooting helps define the untouched forests of the Pacific Northwest.
“It’s a species that a lot of people like and enjoy,” said Robert Fleischer, an evolutionary and conservation geneticist at the Smithsonian National Zoo in Washington D.C.

“It’s hard to put a value on something like that, but it would be a far less rich experience to have Pacific Northwest woods that were lacking spotted owls,” he added.
The owl’s numbers have been dropping by 3 to 4 percent each year.
Habitat loss remains a problem, too. Funk and colleagues suspected that genetic bottlenecking might also add to the owl’s woes.
For their study, the researchers scanned DNA from more than 350 northern spotted owls across the animal’s range.

Then, they ran a bottleneck test, which looks for the loss of certain rare gene-forms, or alleles.

Analyses showed signs that populations of northern spotted owls had indeed shrunk, especially in the Cascade Mountains of Washington.
The loss of genetic diversity is an added blow to the loss of individual birds.
“We knew from census data that there was a problem,” Fleischer said. “We didn’t know it was something that we would see in genetic variation at this stage,” he added. (ANI)

Dinosaurs were actually “thin-osaurs”

London, June 26(ANI): Tyrannosaurus rex, the best-known predatory species, may have been far more lithe than previously thought, researchers have discovered.

In a new study, boffins have claimed that dinosaurs may have been much lighter and sleeker than earlier believed because of potential flaws in the equations used to calculate their weight, reports The Times.

“Palaeontologists have for 25 years used a statistical model to estimate the body weight of giant dinosaurs and other extraordinarily large extinct animals,” said Gary Packard, from Colorado State University, whose research will appear in the Zoological Society of London’s Journal of Zoology this week.

“We have found that the statistical model is seriously flawed and the giant dinosaurs probably were only about half as heavy as is generally believed,” the expert added.

Up till now, dinosaurs have been shown as well-rounded, powerful animals, when they are more likely to have been skinny and muscular.

The new findings would suggest that these animals were leaner and faster, needed less food and had significant differences in lifestyle from what was previously thought. (ANI)

Potentially harmful plant toxins found in forest fire smoke

Washington, May 1 (ANI): In a new study, scientists have detected common plant toxins that affect human health and ecosystems in smoke from forest fires.

The study, which was of Ponderosa pines, was done by scientists at the Department of Energy’s Pacific Northwest National Laboratory (PNNL).

The results from the new study also suggest that smoldering fires may produce more toxins than wildfires, which is a reason to keep human exposures to a minimum during controlled burns.

Finding these toxins, known as alkaloids, helps researchers understand how they cycle through earth and air.

Smoke-related alkaloids in the environment can change aquatic and terrestrial ecosystems, as well as where and when clouds form.

“Ponderosa pines are widespread in areas that are prone to forest fires,” said PNNL physical chemist Julia Laskin, one of the coauthors of the study. “This study shows us which molecules are in smoke so we can better understand smoke’s environmental impact,” she added.

As trees and underbrush burn, billowing smoke made up of tiny particles drifts away. The tiny particles contain a variety of natural compounds released from the plant matter.

Researchers have long suspected the presence of alkaloids in smoke or detected them in air during fire season, but no one had directly measured them coming off a fire.

The PNNL researchers had recently developed the technology to pick out alkaloids from the background of similar molecules.

To investigate chemicals given off by fires, the team captured some smoke from test fires organized by Colorado State University researchers.

The scientists collected smoke samples in a device that corrals small particles.

Using high-resolution spectrometry instruments in EMSL, DOE’s Environmental Molecular Sciences Laboratory on the PNNL campus, they then determined which molecules the smoke contained.

At EMSL, the researchers used the new methods to glean highly detailed information about the smoke’s composition.

The team found a wide variety of molecules.

When they compared their results to other studies, they found that 70 percent of these molecules had not been previously reported in smoke.

In addition, 10 to 30 percent of these were alkaloids, common plant molecules that proved to be quite resistant to the high temperatures of fire.

For future studies, the researchers are developing a method to quantify the alkaloids and related compounds in smoke to better understand their chemical composition and prevalence. (ANI)

Hurricane forecasts make oil sector hopeful

HOUSTON (Reuters) – Forecasts for a relatively quiet U.S. hurricane season have given the country’s storm-weary oil sector hope for reprieve from winds and waves that sank platforms and flooded refineries in recent summers.

Colorado State University’s widely watched weather team downgraded its outlook this week for the number of named storms during this June 1-November 30 hurricane season, pointing to cooler seas and the possibility of a weak El Nino.

Other forecasters are also calling for a quieter hurricane season than last year’s, which produced 16 named storms including a handful that knocked out U.S. offshore oil and gas production and damaged refineries on shore.

“We’re very optimistic,” said Judy Penniman, spokesperson for the American Petroleum Institute. “Hurricanes are dangerous to industry and they are dangerous to people. We would be very pleased if forecasts were true that this year was quieter.”

Hurricane-related disruptions to energy infrastructure can trigger price spikes for gasoline, diesel and globally traded crude oil, and can cause billions of dollars in damage.

“The risk to the oil and natural gas industry is reduced if there is a smaller number of storms,” said Kenneth Medlock, energy fellow at Rice University’s Baker Institute.

But while a quiet hurricane season reduces risk, analysts warn that just one big storm through the Gulf of Mexico can cause enormous damage to the Gulf Coast’s refinery row.

Offshore platforms in the U.S.-regulated areas of the Gulf of Mexico provide a quarter of domestic oil output and 15 percent of natural gas supply, while refineries dotting the coastline produce more than a third of the nation’s fuel.

“Hopefully, we will have a quieter season than in recent years,” said Houston-based Weather Research Center meteorologist Jill Hasling. “But one must remember it is not the number of cyclones that is important but rather where they make landfall.”

WRC has the lowest prediction for the number of tropical storms this season at seven, with up to four of those expected to become hurricanes. That compares to Colorado State’s forecast for 12 named storms, including six hurricanes.

The long-term average for the Atlantic hurricane season is about 10 tropical storms and six hurricanes per year. But experts said a period of heightened Atlantic hurricane activity started around 1995 and was expected to last 25 to 40 years.

The 2008 Atlantic season was one of the busiest on record, with 16 tropical storms, eight of which became hurricanes.

Hasling saw a 70 percent chance a tropical storm will make landfall between Louisiana and Alabama. Louisiana is the geographic heart of refinery row and about 43 percent of U.S. refining capacity stretches from south Texas to Mississippi.

But cooler water in the tropical Atlantic ocean off the west coast of Africa, where storms initially form, may lead to a slower storm season, forecasters said.

“Some of my forecasters have pointed out to me that the tropical Atlantic waters at this time of the year this year are somewhat cooler than the last several seasons,” U.S. National Hurricane Center Director Bill Read told Reuters in an interview. “If that continues that may be a more important factor on this season.”

Tropical storms gains strength from warm sea water.

The NHC will issue its forecast in May.

Private forecaster AccuWeather.com has also said the cooler water and a possible El Nino pattern could cut the number of tropical storms. El Nino, a warming of Pacific waters, can increase levels of vertical wind shear which rips apart tropical storms in the Atlantic.

AccuWeather forecasts 13 named storms including eight hurricanes.

NHC’s Read pointed out forecasting specific weather events from months away is inherently difficult. “That science is still in its infancy.”

U.S. forecaster sees 6 Atlantic hurricanes in 2009

The 2009 Atlantic hurricane season is likely to produce six hurricanes, the noted Colorado State University hurricane forecasting team said on Tuesday.

The storm research team founded by hurricane forecast pioneer William Gray said the six-month season beginning on June 1 would likely see 12 tropical storms and predicted that a weak El Nino event could form during that period.

El Nino, an unusual warming of water in the eastern Pacific Ocean, tends to diminish Atlantic hurricane activity by contributing to strong wind shear that can tear apart nascent storms.

The CSU team lowered its forecast from December, when it predicted the 2009 season would see 14 storms and seven hurricanes.

The 2008 Atlantic season was one of the busiest on record, with 16 tropical storms. Eight of those became hurricanes, with sustained winds of 74 mph or higher.

Last season spawned five hurricanes of Category 3 or higher. A record number of consecutive storms hit the United States.

But Cuba got the worst of last season’s destruction. Three major hurricanes hit the Caribbean island, destroying or damaging nearly half a million homes, flattening sugar cane and tobacco fields and causing an estimated $10 billion damage.

The long-term average for the Atlantic hurricane season is about 10 tropical storms and six hurricanes. But experts said a period of heightened Atlantic hurricane activity started around 1995 and was expected to last 25 to 40 years.

Shoppers tend to see prices’ leftmost digits to determine goods’ affordability

Washington, February 24 (ANI): When it comes to shopping, most people look at the prices’ leftmost digits to determine whether items before them are affordable or not, according to a new study.

“Shoppers pay a disproportionate amount of attention to the leftmost digits in prices and these leftmost digits impact whether a product’s price is perceived to be relatively affordable or expensive,” write authors Kenneth C. Manning of Colorado State University, and David E. Sprott of Washington State University.

Describing the study in the Journal of Consumer Research, the authors revealed that in one of the experiments, the participants were asked to consider two pens, one priced at 2.00 dollars and the other at 4.00 dollars.

The researchers said that the leftmost digit of the price could be lowered by decreasing a penny.

They decided to manipulate the prices, and found that when the pens were priced at 2.00 dollars and 3.99 dollars, 44 percent of the participants selected the higher-priced pen.

However, when the pens were priced at 1.99 dollars and 4.00 dollars, only 18 percent of the participants chose the higher-priced pen.

“The larger perceived price difference between the pens when they are priced at 1.99 dollars and 4.00 dollars led people to focus on how much they were spending and ultimately resulted in a strong tendency to select the cheaper alternative,” the authors said.

The research team further tested the impact of two “round prices”, such as 30.00 dollars and 40.00 dollars, and two “just-below prices”, such as 29.99 dollars and 39.99 dollars.

“When we showed people these sets of prices, most perceived the two round prices to be more similar to one another than the two just-below prices. Based on the perceived price differences, we predicted that people would focus less on how much they were spending when presented with round prices, and as a result, a relatively large percentage of people would opt for the 40.00 dollars option,” the authors say.

However, when buying a gift for a very close friend or when a purchase only involves a few dollars, the authors found that rounding or just-below pricing had no impact on choice.

“Consumers should be aware of the subconscious tendency to focus on the leftmost digits of prices and how this tendency might bias their decision-making,” write the authors. (ANI)
