摘　　要：飞机积冰的发生与云微物理特征密切相关,因此积冰区的云微物理特征分析对飞机的运行安全有重要的意义。利用Cloudsat资料对2016年1月12日和14日的通航飞机积冰过程进行云微物理过程识别分析。结果表明:Cloudsat卫星对积冰过程中的云有很好的识别和探测能力;由于此次飞行高度较低,飞机积冰主要发生在在层积云和积云中,水含量最大值700 mg/m^(3),粒子半径在75μm以上,最大值在150μm以上,发生积冰的温度在-10℃~0℃,飞机积冰情况主要是轻度和中度积冰;Cloudsat卫星能够很好地识别云的类型以及云中过冷水的含量,但未能判定对流云和卷云的情况。The occurrence of aircraft icing is closely related to the cloud microphysical characteristics,so the analysis of cloud microphysical characteristics in the icing area is of great significance to the operation safety of aircraft.Cloudsat data were used to identify and analyze the cloud microphysical process of aircraft icing on January 12 and 14,2016.The results show that the Cloudsat satellite has a good ability to identify and detect clouds in the process of icing;due to the low altitude of this flight,aircraft icing mainly occurs in stratocumulus and cumulus clouds,with a maximum water content of 700 mg mg/m3,the particle radius is above 75 μm,the maximum value is above 150 μm,and the temperature at which ice accretion occurs is-10℃~0℃ aircraft ice accretion is mainly mild and moderate ice accretion;Cloudsat can perform well recognized the type of cloud and the content of supercooled water in the cloud,but failed to determine the conditions of convective clouds and cirrus clouds.
