摘  要:
采用数理统计、归类分析沈阳地区人工增雨案例。结果表明,增雨天气系统主要有东北冷涡、高空槽、华北低压、高压后部和冷锋云系。增雨的适宜高度在云层的中上部约3 000~6 000 m,增雨时机要在雷达监测下,系统移动缓慢或稳定维持且处于发展或成熟阶段。稳定深厚云层宜飞机增雨,不稳定移动快宜火箭高炮增雨。

摘  要:
Using mathematical statistics and classification,the precipitation weather system and radar detection data were analyzed.The precipitation enhancement weather system included the northeast cold vortex,high-altitude trough,northern low-pressure,high-pressure back and cold front cloud system.The appropriate height of precipitation enhancement was about 3 000-6 000 m in the upper part of the cloud.The timing of precipitation enhancement was in the radar surveillance.The system moved slowly or remained stable in the development or maturity stages.The aircraft rainfall enhancement should be taken in stable and deep cloud layers.The rocket artillery rainfall enhancement should be used in unstable and fast-moving clouds.
