摘要
利用绵阳机场ADWR-X雷达资料,探讨了绵阳机场地物回波分布特征以及雷达反射率因、径向速度场对航空危险天气的识别与预报。选取3个典型天气个例,对临近本场突发性强对流云团、高空风动量快速下传以及雷暴群前沿阵风锋等天气进行了分析并利用雷达速度-廓线连续性对径向速度模糊进行修正,得出雷达资料分析应用以及灾害性天气下的气象保障的方法,有利于正确分析处理ADWR-X雷达图像资料,准确判断环境场风场,正确地组织飞行活动,确保飞行安全、高效。
By using ADWR-X data in Mianyang airport,this paper discusses the distribution of ground clutter next to Mianyang airport, identifies and forecasts the aviation hazardous weather according to radar reflectivity factor and radial velocity data. Taking three typical weather cases as the examples, the aviation hazardous weather is analyzed such as sudden severe convective clouds nearing the field, momentum transportation downward of upper wind and the gust fronts produced by frontier of thunderstorms. Based on the continuity of velocity-orientation profiles, the velocity ambiguity of Doppler radar is revised. The methods of meteorological support under atrocious weather are concluded,which can help forecasters deal with ADWR-X radar image data,judge environmental wind field,organize flight activities accurately and ensure the flight activities safety and efficiency.
