Abstract
This paper, basing itself on the pattern of SBDART radiation transmission to get the relation between the height, temperature of cloud top, the effective radius and the bright temperature of the two infrared channels, and on iterative method of repetitive employ of radiation pattern, improves the ways of retrieve, and issues a new way of the combination of multi-station immediate time observation and the data of the 1 and 2 infrared channels to retrieve the height, temperature of cloud top and the effective radius. This paper proves that the improved method, having introduced the immediate time soundings, will improve the accuracy of the retrieve. Through multi-case analysis of the result of the retrieve and the RHI echo of radar and the accumulated precipitation at the meteorological station, this paper concludes that the height of the retrieve cloud top near the radar station often is a little higher than the top of radar echo, and with the increased distance to the radar station the margin will increase accordingly; as for relative stable layer-shaped cloud precipitation, the effective radius of the cloud particle is usually 10 μm, as for fluid precipitation and accumulated cloud precipitation, this does not apply, besides which, effective radius being more than 10μm is not the condition of the precipitation, many stations in this condition do not rain. Through an analysis of the process of an artificial enhancement precipitation, the paper also discusses satellite retrieve product’s operation in artificial enhancement precipitation.
