Discovery of the Day: How to Weaken a Hurricane

The answer lies in Marine Cloud Brightening, exactly what it sounds like.

As Republicans weigh the chances of rain on their parade, and researchers in Miami test an $8 million wind simulator, scientists at the University of Leeds have figured out a way to weaken hurricanes.

The study, by John Latham, Ben Parkes, Alan Gadian and Steven Salter, was published today in Atmospheric Science Letters, and the idea seems surprisingly simple - though execution may be years away. Hurricanes acquire energy from the heat of the surface of the sea, so the researchers set out to lower the temperature of the sea surface. To do so, they propose using a technique called "cloud-seeding," the man-made creation of clouds on display at the Beijing Olympics that soaked rural areas of China to keep the opening ceremony dry.
