| 摘 要： | 运用多普勒天气雷达和天气图资料,对2006年7月6日出现在浙江中西部的1次大面积强降水过程进行了分析,探讨了多普勒天气雷达资料在大面积降水过程中的图像特征。发现在不同的降水时段,垂直风廓线(VWP)产品和径向速度PPI图像都表现出非常明显的特征。利用EVAD技术和变分法计算的散度和垂直速度产品,能比较直观地反映这次过程中大气各层辐合、辐散和垂直运动情况,并以此对浙江大面积降水过程发生、发展、维持和消亡的动力学机制进行了探讨。 |

| Abstract: | Doppler weather radar data and weather graph of a large-ranged rainfall on 6 July 2006 in the west-central of Zhejiang Province are analyzed, and the characteristics of Doppler weather radar products during this large-ranged rainfall case. The results suggest that VWP and VPPI have obvious distinction during different period of rainfall, and it can be reflected directly the conditions of convergence, divergence and vertical velocity in all layers during this case using products of vertical velocity calculated by EVAD and variational method. And based on it, the mechanism of occurrence, development, persistence and collapse of large-ranged rainfall in Zhejiang province is discussed |
