Rain slows whipping hurricane winds

Science News, March 2015

Heavy downpours put a damper on hurricanes, new research suggests. Running simple hurricane simulations, researchers have demonstrated that descending raindrops produce significant friction as they fall along the edges of a hurricane’s eye. This friction slows the powerful winds that drive the storm, lessening the hurricane’s intensity by as much as 30 percent, the researchers report in a paper to be published in Geophysical Research Letters.
