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.
