| 摘 要： | 对吉林省2005年春季（4月19--22日）罕见的降水天气过程在大尺度环流形势、物理条件分析的基础上，重点对其逐时自动站风场资料进行分析，结果表明利用逐时自动站风场分析的中尺度切变对强降水落区、降水强度和强降水发生的时间都具有很好的指示意义；中尺度切变的形成也与地形条件有关。

| Abstract: | A rainy process in spring in 2005 in Jilin Province is analyzed based on its largescale circulation and physical factors, especially the wind data of automatic weather stations. The result shows that the mid-scale shear line ensured by the wind data of automatic weather stations has some relationship with the region, the intensity and the happening time of rainfall, and the geographic effect plays an important role in the appearance of the mid-scale shear line. |

| Keywords: | large-scale circulation wind data of automatic weather stations mid-scale shear line geographic effect |
