摘　　要：应用国家气象中心ＨＬＡＦＳ模式计算的物理参数，对１９９６年长江中下游地区梅雨期一次持续性大暴雨过程形成的物理条件进行了诊断分析，给出了梅雨锋强暴雨的风场、垂直环流及其有关的物理量场结构和分布特征，所得结果有利于实时预报业务和科研工作。ith applying parameters calculated by HLAFS model of NMC, the physical conditions with which associated a persistent severe torrential rain process of the lower and middle reaches of Yangtze river during the Mei yu period in 1996 are analyzed and diagnosed. Wind field, vertical circulation, relevant physical variable field construction and its distribution character of Mei yu front strong torrential rain are presented. All results are benificial to real time operational forecast and research work.
