摘 要: | 分析了2006年6月辽宁2次冷涡天气过程。6月3日的冷涡过程为辽宁大部分地区带来了一次雷雨、冰雹等强对流性天气,云图上表现为白亮云团,雷达上有弓形回波以及辐合型气旋性环流。6月14日的冷涡过程为辽宁大部分地区带来了一次强降水天气。根据雷达速度场可以判断锋面与测站的相对位置。天气形势及预报是短期预报的主要依据,而卫星云图、雷达资料、自动站资料在灾害性天气的监测以及短时预报预警工作中发挥重要作用。

Abstract: | Two cold vortex weather processes in Liaoning Province in June of 2006 were analyzed.In the process of low vortex of Jun 3rd,strong convection weather,such as lightning storm and hailstone,came forth in most areas of Liaoning Province.White and bright cloud was shown in satellite nephogram.Bow echo and cyclonic circumfluence were shown in weather radar production.In the process of low vortex of Jun 14th,strong precipitation weather came forth in most areasof Liaoning Province.Based on the velocity field production of weather radar,the relative place of front and radar station can be judged.The weather situation and forecast were the main basis of short-term prediction.And satellite nephogram,weather radar,automatic weather station play important roles in the monitoring and short-term prediction of disaster weathers. |
