摘　　要：本文利用长春多普勒雷达资料,分析了层状云降水整体VIL及0℃层上、下VIL的分布特点,指出VIL较雷达强度回波更适用于人工增雨作业区域的选择,0℃层上部VIL对北方人工增雨作业区域的选择更具指导意义。Using Doppler radar data of Changchun,the distributive characteristics of whole atmospheric VIL and the VIL above and below the 0 ℃ layer in the cases of the stratiform precipitation are analyzed. It is pointed out that the VIL is more suitable than radar scan intensity echo for the choice of region of weather modification operation and the VIL above the 0 ℃ layer is more suitable for the choice of region of weather modification operation in the north of China.
