本文分析了祁连山中段脚下肃南站的气候和天气特征，以寻找适宜的人工影响天气的天气形势和天数，结果表明：祁连山中段年降水量远大于河西盆地，且降水量随海拔高度的增加而增加;人工影响天气年平均可利用日数为146.4d，年内3 ~ 10月月雨（雪）日数均大于10 d，5 ~ 8月主要为对流性降水。
In this paper,the climate and weather characteristics in Su'nan station which is located at the foot of the mid-section of Qilian mountain are analyzed in order to find the available weather patterns and days for weather modification.Results show that the annual precipitation in mid-section of Qilian mountain is much larger than that in Hexi basin,and the precipitation increases with the height above sea level,the annual average days available for weather modification are 146.4 d,the monthly rainy(snowy) days are more than 10 d from March to October in a year,it is convective rainfall mainly in May to August.
