| 摘 要： | 利用河北新乐多普勒雷达的探测资料和气象常规资料，通过对河北省中南部的两次灾害性天气（2005年7月12日和7月31日）对比分析，得出了对流天气（冰雹、大风）发生时有利的多普勒雷达产品的演变特征，“快速减少的垂直积分液态水可以引起风灾”、“逆风区”是造成灾害性天气的最明显和直接的表现。

| Abstract: | Using conventional observation data and radar data of Xinle Doppler radar in Shijiazhuang, this paper comparatively analyzed two severe weather events occurred in middle - south of He Bei Province separately on 12th and 31st, in July, 2005. It obtains the favorable evolutional features of Doppler radar products on convective weather in Hengshui. such as ＂The rapid reduction of VIL can cause the disaster of wind,＂ and ＂Upwind areas＂. The later is the most obvious and direct the performance of severe weather events. |
