中文摘要: 利用NCEP/NCAR再分析资料、卫星、雷达及飞机等探测资料,综合分析了河南省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飞机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,云气溶胶粒子探头探测的粒子数浓度也高于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:Based on the NCEP/NCAR reanalysis data, satellite, radar and aircraft observation data, the artificial precipitation enhancement conditions of the 5 November 2018 precipitation process in Hennan Pro-vince were analyzed. The results show that the precipitation process was mainly affected by the low-level shear line and the surface cold front. The operational area of the aircraft had a better water vapor condition and a thick ice surface supersaturated layer, and the dynamic conditions were conducive to promoting the development of precipitation. The aircraft operating area was almost full of stratified hybrid clouds, and the cloud system was in a developing stage. In addition, the relationship between the supercooled water area of satellite inversion and the number concentration of the aircraft detection particles was emphatically analyzed. It was found that when using the FY-4A satellite visible light channel, 3.7 μm channel and infrared channel data to conduct the three-color synthesis analysis on the supercooled water in the cloud, the number concentration of particles detected by the aerosol particle probe is also greater than 20 cm-3. They have a good correspondence, indicating that the method analyzing supercooled water in the cloud by the three-color synthesis could be applied to one of the selection conditions of the artificial precipitation enhancement area.
