2010年龙舟水期间赣南一次连续性暴雨过程分析

Analysis of Persistent Rainstorm Process in the Time of Dragon-Boat Precipitation, 2010 in Ganzhou

受高空短波槽和中低层切变线、低空急流、地面静止锋的共同影响，2010年6月14-16日赣南出现了一次大到暴雨、局地大暴雨的降水。本文从引起这次暴雨过程产生的大气环流形势，物理量场，及欧阳首承的渍变理论之“V-3θ”图应用分析，分析了形成连续性暴雨的天气系统、物理量场特征，为今后赣南连续性暴雨的预报提供一定的参考。

Because of the upper shortwave trough, low level jet stream and Quasi-stationary Front, a sustained rainstorm process occurred in city Gazhou of Jiangxi Province from the 14th to 16th in June based on weather situation, physical variables and OUYANG Shoucheng＇s ＂V-3θ＂ graph, the paper has analyzed features of precipitation and weather situation and physical variables which caused the sustained rainstorm. From the analysis we get the more experience and accuracy of forecast to the rainstorm in Ganzhou.
