| 摘 要： | 河南2000年4月14日的降水由冷锋和西南涡产生，降水云系分布不均匀，云图上云区间有带状云隙，雷达回波图上出现两条带状回波，云带内部分布也不均匀，垂直方向上降水云系有分层现象。分析了降水云系的微物理特征，根据可播度的PMS指标确定了航线上过冷水丰富的区域，结合卫星、雷达资料讨论了过冷水丰富区域的分布特征，还讨论了降水云系内部存在的对流不稳定。

| Abstract: | A precipitation process caused by a cold front and a southwest vortex occurred on April 14,2000 in Henan province.The cloud system distributed unevenly.There was a band-shaped gap between two clouds and two band-echoes appearing on radar echo images.Non-uniformity also appeared inside the cloud bands and the cloud system was layered vertically.The microphysical characteristics of the precipitable cloud system were analyzed.The areas with plenty of supercooled liquid water(SLW)were determined according to the PMS indices.Distributing characteristics of the areas with plenty of SLW were analyzed by using satellite and radar data.Evidence of convective unstability of the precipitable cloud system was also observed. |
