A Numerical Simulation on Natural Precipitation Process and Cloud Seeding in Cumulonimbus Clouds with Warm Cloud Base

Combined the fractal dimension with the 2 order statistical features of Gray Gradient Co occurence Matrix ( GGCM) of 4 kinds of basic clouds pictures ( Cirrus, Cumulus, Cumulonimbus and Layer Cloud), the clouds are classified and recognized.
