| 摘 要： | 对1次对流性降水试图根据人工催化所需条件及MM5模式的模拟结果选择适合进行催化作业的部位。研究发现,在该次过程中低层辐合中心同所选催化部位的水平位置有很好的对应关系,因此可将低层辐合中心作为替代的特征物理量,根据其位置确定催化部位水平位置。研究认为某些云体内部有较明显的对流活动,人工影响此类云体时,将探空或微波辐射计资料与多普勒雷达的速度场资料进行综合分析,对选择催化部位有帮助。

| Abstract: | A convective precipitation process was simulated with the MM5 model.The seeding location was found by analyzing both the simulating results and the seeding conditions.A good corresponding relationship was found between the location of the lower convergence center and the seeding location.Locations of the lower convergence center could be an alternate when seeding locations were sought.A conclusion was drawn that the comprehensive analysis of sounding data and doppler velocity is helpful when looking for seeding locations in convective clouds. |

| Keywords: | seeding location lower convergence center Doppler velocity filed microwave radiometer |
