I haven't heard all that much. Is it supposed to be much of storm after it hits land? I thought those things sort of fade away as the trees and ground slow em down. I have my trusty generator and a few cans of gas so I'm ready if a few power lines blow down. <Vonnegut spins in a counter-clockwise circle on his bar stool and says, "Hurricane Shmuricane.

That's where you see convection, where warm air rises and forms clusters of thunderstorms. The Coriolis effect, created by the Earth's spinning motion, may cause this cluster of storms to rotate (counter-clockwise above the equator, or clockwise below), but the system has to be a few hundred miles from the equator for the Coriolis force to exert an effect. If the system becomes organized and strong enough, with sustained winds of 39 miles per hour, it becomes a tropical storm. At 74 miles per hour or more, it becomes a hurricane. A hurricane can be hundreds of miles across. It's like a big engine, with upper-level winds acting as a vent, pulling the rising warm air away from the storm. Rain bands spiral around the center of the system. Air sinks in the clear center, or eye, which can be from 5 miles to more than 100 miles across. Because the atmospheric pressure is so low in the eye, the water rises up there in a sort of mound. This contributes to the devastating storm surge when a hurricane hits land, but most of the surge comes from winds pushing the sea water ahead of the storm, raising ocean levels by several feet. When a hurricane hits land, it tends to weaken mostly because it has lost its source of energy - the warm ocean waters. Friction might slow down the surface wind, but it also can enhance turbulence and therefore gusts, scientists have found. The Saffir-Simpson scale is used to classify hurricanes in the United States. It was invented by engineer Herbert Saffir and former National Hurricane Center director Robert Simpson. <***Note to reader*** All of the capital letters in the above paragraphs were provided by Clappy since everyone knows that Polvo doesn't believe in capital letters.> -AlRokersStomachStaple
