A Study On The Mesoscale And Microscale Structure In Different Types Of Clouds By TRMM Satellite And Cloudsat Satellite

Clouds exert an important and comlpex influence on our weather and climate. Cloud is the object of the weather modification. It provides very important information on understanding the different dynamic conditions, the internal structure and the evolution and on analyzing the temporal and spatial distribution and the micro-macro characteristics of the proper area in weather modification. This paper studies the mesoscale and microscale structural features of the different types of clouds, by using TRMM satellite and Cloudsat satellite data combined with the conventional meteorological data, flight information of the PMS (particle measurement system), and FY-2C satellite data.The inhomogeneous characteristics of the stratocumulus clouds were studied by TRMM satellite. The organization and microscale structure of rainbands and precipitation cores were investigated. Heterogeneous precipitation cloud systems, for example, short echo bands, precipitation cores and homogeneous stratus, have different rainfall rate profiles, which reflected the different micro-physical processes. In our comparative analysis, there is a little conformity between the cloud water content inversed by the TRMM satellite and the cloud droplet number concentration detected by the aircraft. The vertical structure and the microphysical characteristics of the cloud especially the distribution of the ice particles have been studied by Cloudsat satellite data. There is a very good relationship between the top of the cloud detected by Cloudsat satellite and the height of the top inversed by the FY-2C which is running in business. The consistency verifies the accuracy of the modification produce of the FY-2C. The hierarchical structure is founded in the vertical profiles of the ice water content detected by Cloudsat satellite in the freezing rain in the early of the 2008. This characteristic is very consistent with the physical mechanism of the formation of the freezing rain. By jointly applied the TRMM satellite and Cloudsat satellite, the vertical distribution of the precipitable ice and the ice water content is very consistent in the comparatively analyzing. In addition, we use the two satellites to analyze the eye, the outer rainband structure of the 0603 typhoon "Ewiniar" and get the characteristics of the precipitation cloud structure in the different stages. The way to observe the structure of typhoon by the two satellites plays a good potential for application.Above all, this paper studies the different types of typical clouds and precipitation structure by using the TRMM satellite and the Cloudsat satellite data combined with other data. We have recognized some clouds and precipitation in distribution structure and microphysical characteristics. It is of great importance to completely study the cloud and precipitation meso- and micro-physical structure characteristics, the temporal and spatial distribution and the evolution in order to choose the proper area in weather modification.
