| 摘 要： | 使用载有粒子测量系统(PMS)、卫星全球定位系统(GPS)的飞机对2002年9月13日陕北地区一次降水性层状云系进行了有设计的催化、探测飞行。获取了云微物理背景值和影响值，分析发现：催化影响区内小冰晶数量产生了量级上的增加，雷达RHI融化层出现的局部凸起，可能是播撒液态二氧化碳催化后过冷云水消耗释放的溶解潜热导致融化层局部升温上抬形成。

| Abstract: | Precipitation stratiform cloud systems were detected and catalyzed by using airplane with airborne Particle Measuring Systems (PMS) and satellite Global Position System (GPS) in September 13, 2002 in the Northern Shaanxi Province. It shows that in the influenced areas by catalyzing the numbers of little ice crystals increased in order of magnitudes and partial melting layer's prominence in radar RHI was formed because of melting layer's increased local temperature. The cause may be the supercooled water consume melting latent thermal after LC catalysis. |
