中文摘要: 提 要:利用NCEP/NCAR再分析资料、卫星、雷达及飞机DMT等探测资料,综合分析了河南2018年11月5日一次降水过程人工增雨作业条件。结果表明:此次降水过程主要受低空切变线和地面冷锋共同影响,飞机作业区具有较好的水汽条件以及较厚的冰面过饱和层,动力条件有利于促进降水发生发展;飞机作业区主要为层积混合云,云系处于发展阶段。重点对比分析了卫星反演的过冷水区与DMT探测粒子数浓度对应关系,发现当FY-4A卫星可见光通道、3.7 μm通道和红外通道资料进行三色合成分析云中存在过冷水时,CAS探头探测的粒子数浓度也大于20个?cm-3,两者具有较好对应关系,表明三色合成分析云中过冷水方法可应用于人工增雨作业区选择条件之一。
Abstract:Abstract: By using the NCEP/ NCAR reanalysis data, satellite, radar and aircraft observation data, the artificial precipitation enhancement conditions of a precipitation process on 5 November 2018 in Hennan Province were analyzed. The results show that the precipitation process is mainly affected by the low-altitude shear line and the ground cold front. The operational area has good water vapor and a thick ice surface supersaturated layer, and the dynamic conditions are conducive to promoting the development of precipitation. The aircraft operating area is mainly a stratified hybrid cloud, and the cloud system is in the development stage.The relationship between the supercooled water area of satellite inversion and the concentration of DMT detection particles is analyzed importantly. By using the FY-4A satellite visible light channel, 3.7 μm channel and infrared channel data for three-color fusion analysis, it is found that when there is supercooled water in the cloud, and the concentration of particles detected by the CAS probe is also greater than 20个?cm-3.They have a good correspondence, indicating that the method analysised supercooled water in the cloud by the three-color synthesis can be applied to be one of the conditions for selecting the artificial precipitation enhancement area.
