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.
