【摘要】 利用１１架次的机载“ＰＭＳ”资料，分析了山东秋季层状云中高值(大于０．１ｇ·ｍ^－３)过冷水区的微物理特征：最大过冷水含量为０．３６１ｇ·ｍ^－３，８４．０％的过冷水含量在０．１～０．２ｇ·ｍ^－３间，过冷水连续出现的宽度８６．１％小于３．０ｋｍ。雪晶形状以霰粒和小雪粒为主。２阶(函数可以很好地拟合云滴尺度谱，质量谱适合用对数正态函数拟合。更多还原

【Abstract】 he microphysical characteristics in high supercooled water area (higher than 0. 1g. m-3 ) in autumn’s strait form cloud over Shandong were analyzed by means of the datafrom measurements with the particle measuring system (PMS) during 11 flights. The maxi. mum water content is 0. 369. m-3, 84. 0% of supercooled water contents is between 0. 1 and0.2 g. m-3 , 86.1 % of continual distribution width of supercooled water is less than 3km.The shapes of snow crystals mainly is graupel and smaller snow crystals. The cloud dropletscale spectrum can be fitted best by two-order function, and content spectrum can be fittedby log-normal function.更多还原
