摘　　要：利用一架搭载云和降水粒子探头的国王350飞机对2020年1月5日邢台皇寺上空降雪云系的微物理特征进行探测和分析。结果表明:飞机探测时段处于系统发展初期阶段,同一位置垂直上升阶段和垂直下降阶段云微物理特征差距较大;云体结构不均匀,表现为云粒子在垂直高度上呈多层分布,中间有夹层。4300~3100 m高度层的过冷水含量最丰富,峰值达0.3 g/m^(3),对应温度约-9℃。过冷水丰富区出现在逆温层上方,该层最适合开展碘化银增雪作业。A Kingair-350 research aircraft was mounted with a cloud and precipitation particle measuring system and flew over Huangsi,Xingtai,Hebei Province on January 5,2020,for microphysical retrievals of snowfall clouds.The results were as follows:during the vertical sounding period,a gap was found in microphysical properties between the ascending and descending stage at the exact location,which proved the developing clouds.The cloud structure was non-uniform since cloud particles were detected and distributed in several layers with different peak values.The most abundant super-cooled water was at the height of 4.3~3.1 km with a maximum of 0.3 g/m^(3),and the corresponding temperature was-9℃.The area with sufficient super-cooled water was above the inversion layer,where was the most suitable for artificial snow augmentation.
