摘　　要：夏半年用火箭对对流云进行增雨作业,对于抗旱和增加水资源都有重要价值。通过对人工增雨火箭性能和北京地区降水、0℃层高度等天气条件分析,认为火箭作业要选准作业时机,发射仰角根据0°C层高度和射界民居情况确定,一般应掌握在55°~75°之间为宜。作业用弹量根据冷云厚度确定,如厚度6 km左右时,用弹量为4枚。针对一次火箭增雨作业的实例进行了分析。The performance of AgI-loading rockets in rain enhancement operations and the related climate conditions,such as precipitation and the height of the 0 ℃ layer,in Beijing area are discussed.The results show that the rockets launching time should be selected appropriately in rain enhancement operations.The selection of rocket launching elevation should be based on the height of the 0 ℃ layer and the situation of residential building distribution around the operating areas,usually 55° to 75° being appropriate....
