摘要：

利用甘肃省1991 ~2002年飞机人工增雨作业资料，对春末夏初飞机人工增雨作业状况进行了统计分析;按照甘肃省的天气系统特征‘利用探空资料.根据自动化“判别模型”的判别.得出甘肃降水的高空环流可分为三种类型:“平直多波动型、西南气流型和西北气流型.其中降水类型以平直多波动型为多见。通过“判别模型”对飞机人工增雨天气系统的分型.结果表明.飞机人工增雨作业的主要天气类型首先为平直多波动型，其次为西南气流型。

Abstract:

Using the data of aircraft artificial precipitation enhancement operation from 1991 to 2002 in Cransuprovince，the situation of it was analyzed statistically in late spring and early summer. According to the characteristic of weather system of Cransu，making use of sounding data and basing `discriminant model'，we can educe three types of high一level circulation of precipitation. These types were straight but some fluctuant，southwest and northwest air current weather system，respectively. Among the types，the straight but somefluctuant air current weather system emerged morefrequently. The typesof weather system of aircraft artificialprecipitation enhancement operation were sorted by `discriminant model'，result showed that the main type of aircraft artificialprecipitation enhancement operation was straight but some fluctuant air current weather system also，and the next type was southwest air current weather system.

Key words: aircraft artificial precipitation enhancement, late firing and early summer, weather system type
