Another Bad Hurricane Season Approaches

I believe this. Already, with the NOGAPS model loops, you see proto-hurricanes already trying to fire up in the Caribbean and elsewhere, and May isn't even half over yet. The cause is primarily a natural temperature cycle of Atlantic water, and who knows about global warming? Hurricane formation is something like a nucleation phenomenon, and a slight warming can lead to a proliferation of the strongest hurricanes. Conversely, slight cooling could shut down all the big ones.:
In what could signal a frightening new fact of life in the age of global warming, Canadian and U.S. forecasters are warning that another major hurricane season is brewing in the Atlantic Ocean.

The 2006 hurricane season officially opens on June 1, and already scientists are telling people living in eastern North America that numerous storms are predicted, with as many as five major hurricanes packing winds of 180 km/h or greater.

"It's kind of comparable to what we were looking at last year at this time," says Bob Robichaud, a meteorologist with the Canadian Hurricane Centre in Dartmouth, N.S.

"Last year we were looking at 12 to 15 storms and this year the forecast is for about 17. No one would go out on a limb and say it is going to be just as bad as last year, but the indications are there that it is still going to be another active season, almost twice as active as normal."

Last year's hurricane season was the most destructive on record.

There were 27 named storms, 15 hurricanes and seven intense hurricanes during the 2005 season. The worst damage was along the U.S. Gulf coast.

Scientists with the Colorado State University hurricane forecast team say the same factors that contributed to last year's violent season are still in play this year.

"The Atlantic Ocean remains anomalously warm, and tropical Pacific sea surface temperatures have continued to cool," says Colorado University forecaster Phil Klotzbach, explaining two of the key triggers for hurricanes.

..."We are seeing stronger hurricanes - almost a 100 per cent increase in category fours and fives," he says.

"When they do develop, they're a lot bigger, tougher and have more destructive power. They stay together longer. This is the concern. They seem to have more power. That could have a connection to global warming - the fact the atmosphere has changed and ocean temperatures have warmed."

... Phillips says that despite this year's grim forecast, a lot can happen to shut down offshore hurricanes and prevent them from causing onshore harm.

"The temperature of the water has to be right, the winds have to be just perfect, the timing has to be just so and the depth of the water has to be just so," Phillips says.

"It's like baking a souffle. A lot of things have to come together and if someone slams the door, it won't rise."
