Pollution alters isolated thunderstorms: Wind shear strength determines whether pollution swells or saps storms

Thursday, December 17, 2009 - 09:28 in Physics & Chemistry

New research reveals how wind shear -- the same atmospheric conditions that cause bumpy airplane rides -- affects how pollution contributes to isolated thunderstorm clouds. The work improves scientists' understanding of how aerosols -- tiny unseen particles that make up pollution -- contribute to isolated thunderstorms and the climate cycle. How aerosols and clouds interact is one of the least understood aspects of climate, and this work allows researchers to better model clouds and precipitation.
