| 摘 要： | 利用聊城市2004～2006年春季人工增雨作业的雷达回波资料和实况资料，运用统计和对比的方法，对13次高炮和火箭人工增雨的作业云系、作业时机、作业部位以及催化剂量的选择进行综合分析。结果表明：聊城市高炮、火箭人工增雨的作业以混合云和层状云为主要目标云系，层状云作业效率最高，可达80．5％。层状云系作业部位应选在0℃层亮带以上。混合云系应选在强回波区附近。选择催化时机，层状云应在云顶高度≥6km，回波强度≥25dBz；混合云云顶高度≥7．5km，回波强度≥35dBz为宜。1次层状云人工增雨过程在有效作业时段内，1个作业点炮弹以30～40发效果较好，火箭弹2—4枚为宜。

| Abstract: | On the basis of the radar echo and recording data of spring artificial precipitation in Liaocheng from 2004 to 2006,using the methods of statistics and comparison,the selection of anti-aircraft gun,operational conditions,occasions and location of rocket artificial rainfall and quantity of catalyst were analyzed comprehensively.The results showed that the mixed cloud and stratiform cloud were the main objective cloud,and the operation efficiency of stratiform cloud was the highest(80.5%).The stratiform cloud... |
