Using the Doppler radar data in Jilin Province in 2003—2004,the distributive characteristics of whole atmospheric layer vertically integrated liquid water(VIL) and the VIL above and below the 0℃ layer in the cases of the stratiformis continuous precipitation,and convective cloud precipitation are analyzed.It is pointed out that VIL can be used in the selection of weather modification operation region,the analysis of heavy rain processes and severe storms,and the research of precipitation mechanism,etc.
