渭河流域三次暴雨过程水汽和上升运动的垂直结构比较

Comparative Analysis on Vertical Structures for Moisture and Ascending Motion of Three Torrential Rains in Weihe River Valley

摘要: 利用常规高空观测资料和NCEP/NCAR 6 h再分析资料等,着重从水汽和上升运动的垂直结构上对发生在渭河流域的三次致灾暴雨过程进行了比较分析。结果表明:三次暴雨过程具有相似的水汽通量散度场垂直结构,即低层辐合、中层或高层辐散,

Abstract: By using the routine upper-air observations and NCEP/NCAR 6-hourly reanalysis data,the comparative analysis on vertical structures for moisture and ascending motion of three torrential rain processes occurred in
