| 摘 要： | 应用2008年7月1日08时-20时逐3hT639数值预报产品和高低空实况场资料，对2008年7月1日阳泉市的冰雹天气过程进行综合分析，结果表明：T639的24h形势预报场误差不大，但蒙古冷涡中心位置预报略偏北；应用其物理量预报场并结合阳泉本地冰雹的预报指标，能够较为准确的预报出该次大冰雹过程，说明T639数值预报产品对本地冰雹过程有一定的预报能力。

| Abstract: | The analysis of snowstorm on November 10 to 12,2009 in Yuncheng city showed that： ① The westerly trough, ground inverse trough and reflux situation caused this snowstorm. The 700hPa shear line was the main reason for this storm.② The Southwest jet provided plenty of water vapor and water vapor concentration was in low-level convergence. ③Low -level convergence, upper-level divergence, 500hPa adveetion and the strong upward vertical movement provided the dynamical condition for this storm. |
