中文摘要: 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Г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。
中文关键词: 过冷水,云滴尺度谱,微物理特征
Abstract:The 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 and0.2g.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 Гfunction, and content spectrum can be fittedby log-normal function.
