Paper on how vertical wind shear impacts surface winds in hurricanes released online in Monthly Weather Review

Summary: Scatterometers are instruments on aircraft or satellites that are used to measure wind speed and direction at the ocean surface. In this follow-up to a 2016 study, the surface wind in tropical cyclones around the world are studied using a large set of measurements from 2000 to 2011. The impact of tropical cyclone intensity, […]
