摘　　要：文章使用常规MICAPS天气图资料,采用统计学等方法,对袁河流域8 a 14次大暴雨天气过程的天气形势、中尺度和物理量特征进行分析,总结出袁河流域的大暴雨天气发生的时间和分布特征;分析出袁河流域大暴雨天气过程的主要影响系统;并根据袁河流域附近的南昌站物理量场,分析得出袁河大部分大暴雨过程具有高温高湿的特点,且具有较高的不稳定能量。Using conventional MICAPS weather map data and statistical methods,this paper analyzes the weather situation,mesoscale and physical quantity characteristics of 14 heavy rain weather processes in Yuanhe River Basin in 8 years.The occurrence time and distribution characteristics of heavy rain in Yuan River Basin are summarized.The main influence system of heavy rain weather process in Yuan River Basin is analyzed.According to the physical quantity field of Nanchang station near Yuanhe River Basin,it is concluded that most of the heavy rainstorm processes in Yuanhe River have the characteristics of high temperature and high humidity,and have high unstable energy.
