摘要:

选用2000~2003年3~10月,甘肃省实施飞机人工增雨的116架次资料为样本,以增雨当日08时500hPa资料为主,根据冷空气入侵甘肃的不同路径,将有利飞机人工增雨的天气系统分为5种类型:高原低槽型、西南气流型、平直气流型、西北气流型和北方低槽型,并分析了不同系统的特征。

Abstract:

Using the data of 116 times’samples of aircraft artificial precipitation enhancement operation from 2000to2003(March to October),and based on the real time data at 500 hPa at 08:00,five weather types which benefit aircraft artificial precipitation enhancement were obtained according to different path of the cold current in vaing Gansu province:plateau low trough,southwest aircurrent,straight fluctuant,northwest air current and northern low trough.

Key words: aircraft artificial precipitation enhancement, weather systemt ypes, weather characteristic
