Nowcasting of rainstorm based on doppler radar and encrypted automatic observation stations

Analysis of Doppler weather radar echo data of heavy rainfall in Sichuan Basin from 2004 to 2007. Statistical and analytical on Dozens of cases of Heavy Rain, putting forward four Automatic storm warning factors: Composite Reflectivity, Echo Tops, Vertically Integrated Liquid, One Hour Precipitation, Summarized Automatic storm warning threshold factors of The above-mentioned factors. Introduction fusion algorithms, According to Automatic storm warning threshold factors of The above-mentioned factors Read the encrypted automatic station precipitation product information of every hour punctually, Calculated automatic early warning products of Rainstorm, With images and tables in the form of the output. Tests and analysis 3 times Weather during heavy rainfall in July 20, 2008;September 23–28, 2008;and July 14, 2009. This method have Clear warning capacity early on Now casting of Rainstorm.
