摘要
Abstract
Based on the 1°×1°analysis field data from GFS (Global Forecasting System),with a mesoscale numerical model WRF (Weather Research and Forecasting model) ,a torrential rain occurred in Anhui Province from 31 May to 1 June ,2014 was simulated and diagnostically ana-lyzed.The results showed that WRF model has a good forecasting ability in a rainfall process;the coupling of the low-level and upper-level jet was the main dynamical mechanism of the out-breaking of this torrential rain process;the vertical helicity at the upper levels was negative while at the lower levels,it was positive; the atmosphere humidity at the upper levels was damp while at the lower levels it was dry before precipitation.关键词
