Study Shows Poleward Shift In Tropical Storm Peak Intensity
2014-05-15 11:46:07

Brett Smith for redOrbit.com – Your Universe Online A new report from a team of American climatologists has found that the latitude at which tropical storms reach their peak intensity is moving toward the poles – suggesting the term ‘tropical storm’ is slowly becoming somewhat of misnomer. Published in the journal Nature, the new report found that the peak intensity of these storms is moving toward the poles at a rate of about 33 to 39 miles per decade. "We've identified...

Lightning may provide scientists with crucial insight into predicting the intensity of Earth's deadliest storms. Each year, hurricanes pose threats of devastation around the world, and while forecasters have become better equipped to predict their pathways, they often find it difficult to gauge the storms' intensity in advance. Colin Price of Tel Aviv University in Israel and colleagues analyzed the correlation of growth of maximum winds and lightning frequency every 6 hours. Their study...

A distinguished federal scientist has shifted his position regarding the recent increase in hurricanes in the Atlantic ocean, concluding global warming is not the underlying cause. In fact, he believes the warmer temperatures will actually lessen the number of Atlantic hurricanes as well as those making landfall. The conclusion was made in a report released Sunday by Tom Knutson, a meteorologist with the National Oceanic and Atmospheric Administration's (NOAA) fluid dynamics lab in Princeton,...

When the water in the hurricane breeding grounds of the Atlantic warms one degree in the dead of summer, overall hurricane activity jumps by half, according to a new study. Scientists have long known that hurricanes get their enormous energy from warm waters, so the warmer the water, the more fuel a storm has to either start up or get stronger. The study calculates how much storm frequency and strength is due to warmer sea water, said author Mark Saunders, professor of climate prediction at...

WASHINGTON -- The number of tropical storms developing annually in the Atlantic Ocean more than doubled over the past century, with the increase taking place in two jumps, researchers say. The increases coincided with rising sea surface temperature, largely the byproduct of human-induced climate warming, researchers Greg J. Holland and Peter J. Webster concluded. Their findings were being published online Sunday by Philosophical Transactions of the Royal Society of London. An official at the...

WASHINGTON -- The debate over whether global warming affects hurricanes may be running into some unexpected turbulence. Many researchers believe warming is causing the storms to get stronger, while others aren't so sure. Now, a new study raises the possibility that global warming might even make it harder for hurricanes to form. The findings, by Gabriel A. Vecchi of the National Oceanic and Atmospheric Administration and Brian J. Soden of the University of Miami, are reported in Wednesday's...

WASHINGTON -- The Bush administration has blocked release of a report that suggests global warming is contributing to the frequency and strength of hurricanes, the journal Nature reported Tuesday. The possibility that warming conditions may cause storms to become stronger has generated debate among climate and weather experts, particularly in the wake of the Hurricane Katrina disaster. In the new case, Nature said weather experts at the National Oceanic and Atmospheric Administration - part...

WASHINGTON -- Most of the increase in ocean temperature that feeds more intense hurricanes is a result of human-induced global warming, says a study that one researcher says "closes the loop" between climate change and powerful storms like Katrina. A series of studies over the past year or so have shown an increase in the power of hurricanes in the Atlantic and Pacific oceans, a strengthening that storm experts say is tied to rising sea-surface temperatures. And most of that temperature...

By Timothy Gardner NEW YORK (Reuters) - Some 250,000 evacuees from last year's Hurricane Katrina on the Gulf Coast may never return permanently and should be considered "climate refugees," whose ranks around the world could grow until global warming is mitigated, an environmental expert said. The number of "climate refugees" will grow unless the world cuts the amount of greenhouse gases it releases, said Lester Brown, president of Earth Policy Institute in Washington D.C. "What...

MIAMI -- Officials tracking the approach of the peak hurricane season told President Bush on Monday that data linking a series of devastating storms to global warming was inconclusive. Eleven months after Hurricane Katrina wreaked havoc on the Gulf Coast, causing catastrophic flooding in New Orleans, Bush visited the National Hurricane Center in Florida, a state often battered by hurricanes. Max Mayfield, the center's director, said he is often asked whether the powerful hurricanes of recent...
