Gustav was the seventh named storm in the 2008 Hurricane season, and we quickly have four more, including three in the Atlantic.
Hanna has hit Haiti leaving at least 10 dead and could hit the East coast as early as Friday. It is currently a tropical storm, but forecasters say it could be back to hurricane strength again before making landfall on the East coast. Check out the storm track for this storm here.
Ike is headed to the area of the Bahamas and could reach the area by Sunday. The area would then have been hit by four storms in a row, Fay, Gustav, Hanna and Ike. Check out the storm track for this storm here.
Tropical storm Josephine formed today and hurricane center said it could near hurricane force by Wednesday or Thursday. Check out the storm track for this storm here.
In the Pacific Karina is a new storm that at this point does not pose any risk to the West coast or other inhabited areas in the Pacific.
My homepage: This is my homepage with a couple of the mentioned gadgets.
Courtesy JoeIf you are interested in tracking hurricanes, typhoons, tropical storms, etc. there is a cool gadget available for your Google hompage (and probably others) that allows you to view, track and interact with maps that show the most current active of these tropical weather systems. Its an interesting way to keep up and monitor the systems - and remind yourself that they happen all over the world. The one I use is here but I am sure there are others that are similar.
There are also gadgets for earthquakes, volcanoes and even one specific to world disaster photos.
A prominent federal meteorologist has reversed his stance on global warming’s role in the recent increase in hurricanes. Tom Knutson, a researcher for the NOAA fluid dynamics lab in Princeton, has published a new paper in the journal Nature Geoscience predicting that Atlantic hurricanes will decrease by 18 percent by century’s end.
The new study is already brewing up a storm of its own because Knutson has complained in the past of being censored by the Bush administration for his previous views of climate change’s adverse effect on weather. Not surprisingly other researchers contend Knutson’s new computer models are flawed. Read the full story here.

Hurricanes and global warming: The debate over their connection continues.

In 2005, Dr. Kerry Emmanuel, a climate scientist at the Massachusetts Institute of Technology, published a paper claiming there was a link between rising global temperatures and increases in hurricane strength.
This year, Dr. Emmanuel has published another paper in which he reconsiders the evidence. He found that the models used to predict hurricane activity were not matching up with what was happening in the real world. The link between hurricanes and global warming may not be as strong as originally suspected, or may not exist at all.
This is precisely how science is supposed to work – examining evidence, coming up with theories to explain the evidence, testing those theories, and adjusting the theories if necessary.
In another three years, Emmanual may write another paper showing that he was right the first time. Or that the whole hurricane-warming link is a dead end. Or perhaps some other conclusion. But the important thing is to keep looking, and to report honestly what you find.
As economist John Keynes famously said, “When the facts change, I change my mind.” A good approach to any debate.
Is the number of hurricanes rising, or are we just getting better at counting them?

The 2007 hurricane season ends today, and by most accounts it was fairly typical, with 14 named storms and 5 hurricanes. But Neil Frank, former director of the National Hurricane Center, thinks those numbers are inflated. He argues that several of the named storms were not, in fact, strong enough to merit special designation.
According to the article, better storm-tracking technology has allowed scientists to identify and accurately measure weather events which, in years past, might not have merited “storm” designation, or might have been missed altogether.
Some people argue that this is an example of “climate change hype” – exaggerating the number of strong storms to make climate change look more severe than it actually is. Blogger Glenn Reynolds has perhaps a more charitable explanation: people in any profession want their field to seem important. If you’re in the hurricane business, then you get more attention – and more funding – if there are more hurricanes.

The Atlantic Hurricane season ends this week, and it seems to have fallen short of earlier dire predictions. The 2005 season, with Hurricanes Rita and Katrina was far above normal, leading to some hasty predictions of intense storms to come. The last two seasons were much closer to normal, showing just how much random fluctuation there can be in a dynamic system like weather.
Hurricane help: New research is finding that the churning waters from hurricanes can speed up the recovery of coral beds suffering from coral bleaching. (Photo from the National Oceanic and Atmospheric Association)After seeing the devastation wrought by Hurricane Katrina, among other recent storms, hurricanes have been fighting a losing p.r. war. They’re just plain bad, right?
But new research is showing that the effects of hurricane weather can have a positive impact on some coral beds, particularly those that are suffering from stress caused by warming water temperatures. Ironically, warming waters is one of the factors that lead to more and bigger hurricanes.
A team of researchers from the National Oceanic and Atmospheric Administration has found that hurricanes off of Florida and the Virgin Islands in 2005 were a benefit to “bleaching” coral beds in those areas. The bleaching problem is caused by the loss of algae in the area and a reduction in the pigments of the corals in the area when they’re stressed by warm weather.
Hurricanes Rita and Wilma in 2005 stirred up the waters of those bleached coral beds and were able to lower the water temperatures in the impacted coral beds by as much as nine degrees.
That water temperature saw a quicker recovery rate for the bleached coral beds. The researchers also point out that a direct hit by a hurricane to a coral bed still did vast damage, but areas on the edges of the storm showed improvement on the bleaching condition. Those improvements could be seen as far as 250 miles away from the hurricane’s main path.
