一次雷雨大风天气的多普勒雷达资料分析
Analysis on Doppler radar data of a thunderstorm and gale weather
摘要
Abstract
By using conventional observation data and radar data,a thunderstorm and gale weather happened in Anyang on 4th Agu,2010is analyzed.The results show that the shape of '人' formed by multiple echoes is displayed on the reflectivity map of Doppler radar,which can enhance the convection.Short-term strong rainfall and ground gale appear on the top of '人' and its moving path.Thunderstorms are observed from radial velocity diagram that appears the zone of against the wind and large radial convergence.Meanwhile,the heavy rain and gale display within this zone and its moving path.The time and drop zone of short-term strong rainfall,thunderstorms and local winds are corresponding to appearance time and location of the cyclone in radar echo path.During this process,it appears higher radar echo top,strong echo and vertical accumulation liquid water content with higher height in the layer of 0℃.Live weather is mainly of the strong thunderstorm,short-term strong precipitation and local gale without the hail.关键词
