Abstract

This award supports the study of cloud electrification and lightning using phased-array weather radar. The research team will deploy multiple mobile radars to the field to observe key aspects of thunderstorms. Phased-array radars provide extremely fast sampling compared to traditional radars, allowing measurement of lightning features that were previously difficult to observe. Improved knowledge of lightning…
