| 摘 要： | 利用多普勒雷达资料的强度场、速度场、垂直累积液态水含量等资料,对2009年7月29日呼和浩特市及以西地区的1次中到大雨天气过程进行了分析。结果表明：由不同仰角的PPI图和多普勒雷达径向速度场的变化来判断未来雷达回波的强度及移动方向,对临近预报有重要作用;观测垂直累积液态含水量VIL值的变化可以预报对流天气形成的可能性。 |
| 关 键 词： | 多普勒天气雷达 强对流 天气背景 |

| Abstract: | The sever convective precipitation process occurred over Huhhot and west of it through night in July,2009 was analyzed using the doppler weather radar of intensity,vector,VIL.The features of sever convection were analyzed in order to improve the ability of weather forecasting at the occurring and grown time of convective precipitation.It was very important that change of radar echo intensity and shifting were determined due to change of PPI chart and Doppler vector in every elevation.Precipitation time and area can be forecasted well by VIL. |
| Keywords: | Doppler weather radar sever convection synoptic background |
