, scheduled to be published online on May 18 in Nature Geoscience. Knutson’s co-authors are Joseph Sirutis, Stephen Garner, Gabriel Vecchi, and Isaac Held. The scientists performed hurricane simulations using a new regional model that offers both higher resolution and an improved ability to simulate past observed changes in Atlantic hurricane activity. In a preliminary study published last October in the Bulletin of the American Meteorological Society, the new model was shown to successfully reproduce Atlantic hurricane counts year-by-year from 1980 to 2006, including the observed increasing trend. In the new study, the model was used to test the influence of greenhouse gas warming on Atlantic hurricane activity through the end of the 21st century. Simulations reveal higher levels of wind shear and other changes, which act to reduce the overall number of hurricanes in the model. Tropical Atlantic sea surface temperatures have increased over the past century and several studies have reported strong correlations between increasing tropical Atlantic sea surface temperatures and measures of hurricane activity since at least 1950… These results support recent research showing that the primary driver of the recent increase in Atlantic hurricane numbers was the warming of the tropical Atlantic relative to the other tropical basins. These results are also consistent with a number of previous modeling and theoretical studies that have examined the influence of global warming from increasing greenhouse gases on hurricane intensity. An increase in hurricane intensities globally is assessed as "likely" in the Intergovernmental Panel on Climate Change Fourth Assessment Report issued in 2007. Adapted from materials provided by.
Study: Early Warnings May Boost Tornado Deaths

com’s Natural Science Center. The researchers say they don’t have enough evidence to conclude that greater advance notice is a bad thing, but their findings do indicate that more warning time alone may not be the answer to tornado threats. “If an F-5 [the most severe type of tornado] hits your house, unless you’re in a [reinforced] safe room, it probably doesn’t matter if you had two minutes of warning or an hour of warning,” said Kevin Simmons, an economist at Austin College in Texas who conducted the study with economist Daniel Sutter at the University of Texas-Pan American. “That thing is so powerful, there’s a pretty high probability you’re going to be injured or killed. Related Stories… Overall, when people were notified of a tornado up to about 15 minutes ahead of time, deaths decreased. However, lead times greater than 15 minutes seemed to increase fatalities compared with no warning. The scientists think this result is explained by a handful of the most severe storms. “If you just look at it on the surface, you could come up with the conclusion that extra warning doesn’t pay off,” Simmons told LiveScience. “But when you break it down and look at what’s driving that result, you find that the storms that are much larger are also the storms that are on the ground the longest, and those storms are the easiest ones to detect, so they’re almost inevitably going to have longer lead times.
Ex-Hurricane Center chief ends career as TV weatherman
USA Today – May 20, 2008
The former director of the National Hurricane Center is retiring after 20 years as chief meteorologist at Houston television station KHOU. Frank announced his retirement during the station’s 10 p. KHOU reports on its website that Frank will continue to provide the station with special weather projects and hurricane coverage… KHOU reports on its website that Frank will continue to provide the station with special weather projects and hurricane coverage. Frank joined the station in June 1987 after 26 years with the National Weather Service’s hurricane center in Coral Gables, Fla. The final 13 years at the hurricane center were as its director, in which the crewcut Frank became a familiar television figure during whenever hurricanes approached the U.

African dust forecast could be new hurricane tool
Reuters AlertNet – May 20, 2008
Such a small difference can make a large difference in the number and intensity of hurricanes that form. Interest in African dust rose after the disastrous 2004 and 2005 hurricane seasons, when dust levels were low. Four powerful storms hit Florida in 2004, while 2005 shattered records with 28 storms, including Hurricane Katrina, which caused $80 billion in damage on the U. "We expect to see a lot more dust this year than we saw in 2004 and 2005," Evan said. "On average that could lower the ocean temperature not even half a degree Celsius, maybe half a degree Fahrenheit.

But then the Nobel laureate went on toblame Katrina on man’s energy sinfulness. ” In fact, Gore stated that “any individual storm can’t belinked singularly to global warming. ” Asked about Hagee’s comment regarding Hurricane Katrina, Gore responded: “Well, my friends in New Orleans said,’Well, if that’s the case, how come God spared the French Quarter?’Of course that’s silly. ” From the May 6. org%2Ftemplates%2Fstory%2Fstory… But, you know, one reaction to Katrina, one now-famousreaction, was from Pastor John Hagee, whose endorsement John McCain sought. GROSS:And on our show about Hurricane Katrina, he said, “All hurricanes are actsof God because God controls the heavens. I believe that New Orleans had a level of sin that wasoffensive to God, and they were recipients of the judgment of God for that. Ibelieve that Hurricane Katrina was, in fact, the judgment of God against thecity of New Orleans. And he went on to explain that this was punishment for a gay pride parade thatwas about to happen that promised to reach a level of sexuality neverdemonstrated before in all of the gay pride parades. So what do you think aboutwhen you hear a reaction like that to Katrina?GORE: Well, my friends in New Orleans said, “Well, if that’s thecase, how come God spared the French Quarter?” Of course that’s silly.
