| Abstract: | Based on the hourly infrared cloud images from the geostationary meteorological satellite(FY-2) and the enhanced precipitation observation from the regional mesoscale surface automatic weather observation network,through the parameterization of cloud images,the relationship between cloud parameters and precipitation rate of different categories are analyzed by using the dynamical correlation method.The cloud parameters include the two-band combination of long-wave infrared and split-window,the two-band comb... |
