【摘要】 对2007年3月16日河南层状云的飞机探测资料进行了较详细的分析。结果表明,FSSP-100观测的小云粒子(包括小云滴和冰晶)总数浓度变化在0.2263×106～46.9436×106个/m3,平均值为1.9759×106个/m3;粒子平均直径最大值为23.4μm,最小值6.8μm,平均为14.8μm。2D-C观测的云中大云粒子总数浓度变化在13.297×103～65.060×103个/m3,平均值为38.638×103个/m3。机载King热线液态含水量仪观测云中存在过冷云水,过冷云水含量在云底部较小,为0.06g/m3,随高度上升过冷云水含量增加,在3968m最大,为0.218g/m3,平均值为0.143g/m3。云中粒子谱型主要有单峰型、双峰型、多峰型和负指数型。更多还原

【Abstract】 The cloud micro-physical data sampled with probes of Particles Measuring System (PMS) on 16 March 2007 in Henan Province were analyzed.The results showed that the concentration of small particles sampled with FSSP-100 probe changes from 0.226 3×106 ind/m3 to 46.943 6×106 ind/m3.The mean concentration is 1.975 9×106 ind/m3.The mean diameter is around 6.8-23.4μm,the mean is 14.8 μm.The data of 2D-C probe showed that the concentration of large particles changes from 13.297×103 ind/m3 to 65.060×103 ind/m3,the mean is 38.638×103.The maximum water content explored with King-LWC probe is 0.218 g/ m3 at 3 968 m,the mean is 0.143 g/m3.The cloud droplet spectra includes single-peak type,bimodal type,multi-peak type and negative exponential type.更多还原
