一、引言机场的天气受各种不同尺度天气现象的综合影响。全球数值预报模式已经成功地应用于航空领域,特别是中小尺度的分析,对于机场飞行器的飞行安全尤为重要。同时,多普勒天气雷达可以探测到降水内和晴空大气中水平风场和铅直风场、降水滴谱和大气湍流,可以探测冰雹、下击暴流等。 I. INTRODUCTION The weather in the airport is affected by the weather phenomena of different scales. The global numerical prediction model has been successfully applied in the field of aviation, especially in small and medium-scale analysis, which is especially important for the flight safety of airport aircrafts. At the same time, Doppler weather radar can detect horizontal and vertical wind fields, precipitation droplet and atmospheric turbulence in precipitation and clear-air atmosphere, and can detect hail and downburst.
