摘　　要：低空风切变是航空器起飞、着陆阶段威胁飞行安全的危险因素。文章根据首都机场风廓线探测资料,按照雷雨型、锋面型、逆温型、低空急流型和其他型,对产生的低空风切变过程进行了分类和统计;并利用风廓线探测资料,个例分析了几种产生低空风切变的风场特点。The low-level wind shear is the risk factor that threatened the flight safety during airplane taking off and landing. Based on sounding data from the capital airport wind profiler, the level wind shear is classified by the following the thunderstorms type, frontal type, inversion type, level jet type and other types. By using sounding data of wind profiler, wind field characteristics of level wind shears are analyzed.
