| 摘 要： | 对祁连山区降水过程的大尺度天气类型：西南气流移动型、西南气流阻塞型、西北气流冷平流型、河套冷涡型和平直西风气流型，分类选取典型个例，对各类型产生降水的环流特征、副热带西风急流、垂直速度、水汽输送和水汽汇、影响降水的天气系统和稳定度等进行诊断分析，并对照云图分析了地形云和对流云团产生的条件，降水强度等。

| Abstract: | According to the macro-scale synoptic patterns of precipitation processes over Qilian mountains,including southwest air current moving,southwest air current blocking,northwest air current cold advection,Hetao cold vortex,and flat westerly air current,the typical cases for differrent patterns were selected to analyze circulation character,subtropical westerly jet,vertical velocity,vapor transport,vapor flux convergence,synoptic system and potential instability index of each synoptic pattern which generated p... |
