Precursor dynamical factors in the local lower atmosphere of warm-sector heavy rainfall over South China: evidence from wind profiler radar observations
Abstract. Using 14 wind profiler radars and hourly records at 3000 weather stations during 2016–2020, 226 warm-sector heavy rainfall (WSHR) events were identified in Guangdong, South China. Five indices reflecting the vertical structure of the atmosphere were analyzed as precursor dynamical signals of WSHR occurrence –...
