Hurricanes come mostly in July and August. June is early, September is late, so when we vacation in Florida we either go in June or Labor Day weekend. But one thing you can't predict is the weather. Maybe the wind cycles are not moving heat from Pacific into Atlantic? Might explain why US west coast is so hot. >>Global warming's effect on hurricane strength disputed in new report The Associated Press July 28, 2006, 4:09 PM EDT MIAMI -- Scientists linking the increased strength of hurricanes over recent years to global warming have not accounted for outdated technology that may have underestimated storms' power decades ago, researchers said in a report published Friday. The research by Chris Landsea of the National Hurricane Center challenges two studies published last year by other respected climatologists. One of the studies, by Kerry Emanuel of the Massachusetts Institute of Technology, was considered the first major research to challenge the belief that global warming's affect on hurricanes was too slight to accurately measure and that climate change likely won't substantially change tropical storms for decades. And, if Landsea and his three co-authors are correct, it was fundamentally flawed. ``The methodology is fine. There's no problem with the way they analyzed the data,' said Landsea, who is science and operations officer at the hurricane center. ``The problem is with the data itself.' The study claims historical storm data has been rendered out-of-date by new technology that better estimates the strength of hurricanes. He pointed to advancements in the quality of satellite imagery that is used to estimate a storm's strength when it can't be directly measured by aircraft or on land. In short, Landsea said, there were far more Category 4 and 5 storms in decades past than previously thought, because satellite imagery has improved so greatly. The article was published in the journal Science. It is co-authored by Bruce Harper, an Australian engineer who is an expert on Pacific cyclones; Karl Hoarau, a professor at Cergy-Pontoise University in France; and John Knaff, a researcher at the National Oceanic and Atmospheric Administration. It looks at only a small sampling of historical storm data, though the authors plan to examine further hurricane information they believe will further prove their thesis. <snip> More at:sun-sentinel.com
