Abstract
Ab srt act According to the precipitation data of seven elements of automatic meteorological station, the precipitation data of regional automatic weather station and the conventional observation, we comprehensively analyzed a regional heavy rainfall weather process in west and south Guizhou Province affected by typhoon Haiou from 8:00 on September 16 to 8:00 on September 19,2014 .Results showed that under the favorable large-scale conditions,cold trough on 500 hPa long wave and strong East airflow blocked the typhoon moving to north.The path of typhoon was west.Long wave guided the cold air move toward to south , with invasion of the typhoon depression, and the increase of convergence motion.The invasion of cold air made the whole structure change into the"warm up and cool down".The high and low altitude power, heat, water vapor and unstable conditions in Guizhou Province were beneficial for the rainfall process .The special landform of west and high east low in southwest re-gion played an important role in the intensity of the heavy rainfall and its predicted area.关键词
