| 摘 要： | 利用常规气象资料、卫星云图、ECWMF数值预报产品等,对2006年6月2到3日出现在西南地区的一次区域性大到暴雨天气过程的环流形势、物理量场等进行了分析,结果发现:来自于孟加拉湾的水汽不断向西南地区上空输送;高层辐散、中低层辐合、不稳定能量不断积累等有利于暴雨的产生。ECWMF数值预报对高空槽、低空切变的发展以及低层温度预报与实况基本一致,对暴雨预报有很好的指示意义。

| Abstract: | By using conventional meteorological data,satellite image and the products of ECWMF,a regional heavy-hard rainfall weather process in the southwest China on June 2nd to 3th 2006 was analyzed on circulation pattern and physical quantity field.The results show that the accumulation of the water vapor from Bay of Bengal continually transported over the southwest China, upper-lever divergence,middle and low lever convergence and instability energy have advantage in bringing about rainstorm.The results of upper trough,the development of lower-shear and lower-level temperature forecast from the products of ECWMF are basically in consistence with the true values,and have great indicative significance for rainstorm forecast. |
