The Hanjiang River Atmospheric Precipitation TuPu Research Base On WRF Model

With the high speed development of Atmospheric sciences and atmospheric remote sensing technology and high-performance computers,the numerical prediction quality and accuracy is greatly improved. It has streng ability to portray the atmosphere complete dynamic processes. Numerical models of atmospheric simulation is more realistic. In the the forecast meteorological processes,we can study the internal mechanism of the atmospheric processes at the same time.In the field of meteorology, available numerical interpretation focuses on computing, lack of visuals means and systematic process flows,this article has executed the mesoscale meteorological numerical simulation experiments in hanjiang river, focus on precipitation and its related factors.Mainly Completed the following work:First has performed an analysis of meteorological environmental conditions of the Hanjiang River, designed precipitation numerical perimental program,and selected the appropriate parameters and physical processes.Using the Computer visualization technology GIS to display numerical model WRF forecast products.And base Geo-Information TuPu theory superimposed layers and other spatial information related indicators Homologous to produce the basis signs precipitation TuPu,the precipitation diagnosis TuPu and so on. Verify a the low tropospheric water vapor conditions and the Hanjiang River rainstorm corresponding relationship; when the Rainfall increase,the numercial model forecast accuracy reduced.Produced the underlying surface TuPu and Data assimilation TuPu.Descript it is better to forecast precipitation simulation using data assimilation in the rainstorm level.The use of TuPu interpretation of numerical products provide a convenient way to reveal the precipitation process, precipitation and Spatial Variation of the relevant factors, but also for forecasters and weather researchers a new perspective analysis of the understanding of the occurrence of the weather system, the mechanism of precipitationplayed a catalytic role.
