雷暴云中闪电放电条件下的雨滴增长

从考虑雷暴云中电场力作用的水滴运动方程出发，利用球的正面阻力系数ψ和雷诺数Ｒｅ的实验关系，计算出水滴在外力作用下的瞬时运动速度，从而计算出环境电场作周期性变化时水滴增长的规律。

RAINDROP GROWTH UNDER THE CONDITION OF LIGHTNING DISCHARGE IN THUNDERSTORM

The experimental relationship between coefficient of spherical drag and the Reynolds number was used in equations of raindrop motion with considering electric field force in thunderstorm. The instantaneous velocity of raindrop effected by external and law of raindrop growth were calculated under the periodic variation of environmental electrical field. The results indicated that the effect of lightning discharge on the growth of smaller drop was large and the effect degree was close related to charge carried by drop. If some droplets can carry a large number of charge by some artificial ways,this may be a new method of artificial precipitation stimulation in thunderstorm.
