摘要
利用单多卜勒天气雷达风场资料对一维径向、一维方位、二维复合风切变值进行了计算 ,并对机场附近飞机所受气流速度变化进行分析。所得结果旨在定量描述机场附近低空风切变区 ,检验对下击暴流、中气旋、阵风锋探测的结果 ,确定飞机起降潜在危险区。
The velocity data for a single Doppler radar have been used in this paper to compute the feature values such as one dimensional radial shear,one dimensional elevation shear and two dimensional radial and elevation shear,and the effect of airflow on airplanes has also been analised.The study is to recognize the areas of wind shear,verify the observations of microburst,mesocyclone and gust front,and define the potentially dangerous areas for airplane during landing and taking off.The system can be regarded as an efficient tool to guarantee a safe flying.
