| 摘 要： | 利用PMS云粒子测量系统和GPS定位系统探测了2002年4月28日一次冷锋天气过程。用取得的资料分析了此次过程云滴、冰晶等云微物理量的水平、垂直分布,以及谱的特征,确定出最佳谱模拟参数,揭示了其中发生的微物理过程。从微观角度说明了甘肃春季冷锋天气过程层状云的一些特点。并讨论了云系的增雨潜力。

| Abstract: | Based on the data measured by PMS and GPS during a cold front process on April 24,2002, the horizontal and vertical distributions and spectrum characteristics of microphysical quantities of cloud drop and ice crystal were analyzed in this paper. And the optimum parameters of simulated functions were given out, the possible microphysical mechanism which involved were discussed. On these facts, the potential ability of enhancement rainfall was discussed and estimated. |
