摘要
利用1993-2004年高空和地面资料,统计分析了祁连山降水环流特征,得出祁连山降水的主要形势为高空冷槽型、西南气流型、西北气流型。预报系统04年业务化以来,增雨条件判断准确率70%,对人工增雨业务具有客观的指导意义,并有助于对增雨效果的检验。
Based on the ,data of aerological and surface meteorological observation from 1993 to 2004, the characteristics of precipitation in Qilian Mountain was analyzed statistically. Results showed that main types of precipitation in Qilian Mountain were cool trough, southwest and northwest air current. Forcast system was applied to operation since 2006. The accuracy reached about 70%, and supplied an objective guiding meaning for artificial precipitation. Which also could be used to analyze the effect of artificial precipitation.
