It is presented that indirect assimilation experiment of CMW data from TCFM method improves effectively not only on vertical velocity field but for precipitation.4 Based on theory analysis, E-Ir relationship is brought forward with two electrification mechanisms. One is inductive mechanism, i.e., cloud particles collide with precipitation particles then flick away, the other is noninductive mechanism because of different temperature, i.e., bigger supercooled cloud particles collide and freeze with hail particles combined with ice scraps. By means of CINRAD and FY2C data assimilation, precipitation intensity Ir can be obtained, then electric field intensity E, discharge time and locations can be achieved with supposed threshold 300KV/m. Though it can not distinguish between IC (Intra-Cloud) lightning and CG (Cloud-to-Ground) lightning, results are still comparable to LLS observations.5 Example analysis shows that the relationship between precipitation data from AMS and CG data from LLS is not very clear.

同化实验对于台风眼区的螺旋形雨带贡献显著，说明TCFM云导风资料同化实验不仅有效调整了模式的垂直速度场，还对降水模拟有了明显改善。4通过理论分析，利用云粒子与极化降水粒子碰撞并弹离的感应起电机制和较大过冷云滴与雹粒碰冻并产生冰屑的温差起电机制下得到的E-Ir，由雷达、卫星遥感资料直接和间接同化模拟得到Ir，来反推E，了解雷暴云中闪电强度的平面分布，设置放电阈值为300KV/m，推算出放电的位置和首次发生闪电的时间。
