中文摘要: 应用Barnus带通滤波方法,对2001年5月30日～6月2日云南初夏罕见的暴雨天气过程进行了尺度分离,初步揭示了此次暴雨天气发生的流场、能量场和动力场的中尺度特征,对提高暴雨天气预报能力具有积极意义。

Abstract:With the aid of band pass filter,and scale separating method,the various mesoscale systems of a torrential rain occurred in Yunnan area from 30 May to 2 June in 2001 are analyzed.The results show that some mesoscale weather characteristics such as the instability energy,the streamline field and the dynamical structure before the torrential rain are very clear.It is highly importance for us to improve the forecast of torrential rain events.
