Though it's a nice idea, artificially cooling ocean surfaces won't do much to stop the destructive power of a hurricane.
FORT LAUDERDALE, Fla. — The news comes from a recent study by scientists at the University of Miami Rosenstiel School of Marine, Atmospheric and Earth Science.
To figure that out, Hlywaiak and co-author David Nolan compared two models of hurricane assessment. The simpler of the two, the maximum potential intensity theory, is commonly used to determine the maximum velocity of tropical storms. The study authors' model simulated an approximately Category 4 hurricane encountering an area of cooled water larger than the state of Oregon — that's nearly twice the size of Florida. They set the patch at 3.6 degrees Fahrenheit cooler than the surrounding water and found that the hurricane weakened by only 15%.
"Hurricane Sandy is a good example. It was the equivalent of a Category 1 storm, yet it was still one of the most devastating hurricanes on record due to the sheer size. As we say in Miami, there's more to the story than the category.
It travels about a mile above the water's surface at 30 mph to 50 mph and can cut into storms, tearing them apart. These winds typically dissipate in mid-August.
