| 摘 要： | 利用已有的二维雷暴云起电模式,加入气溶胶模块,建立一个完善的雷暴云起电模式.结合SEET个例,初步探讨了气溶胶浓度对雷暴云内各种水成物粒子荷电情况的影响.发现气溶胶的浓度与雷暴云内云滴、霰粒、冰雹以及雨滴等水成物粒子在空间所携带的最大电荷面密度值以及电荷量有很好的正相关性;同时气溶胶粒子浓度的增加使得雨滴在空间携带电荷量达到峰值的时间有一定提前.

| Abstract: | In this article,a complete thunderstorm electrification model is proposed by adding the aerosol module to the existing two-dimensional thunderstorm electrification model.The SEET case is used to discuss the effect of different aerosol concentration on the electric charge of various particles in thunderstorm cloud.The result shows that a good positive correlation exists between the aerosol concentration and maximum charge density/quantity carried by particles like the cloud droplet,graupel grain,hail or raindrop in the thunderstorm cloud,and the increase of the aerosol particle concentration will bring forward the time of the charges brought by the raindrop to reach its peak. |
