A technique of satellite image recognition with computer, mathematical morphology combined with syntax pattern recognition,and cloud system structure connected with synoptic system,is introduced. With the technique,a test of recognition of cloud system of a typhoon process is made. The result shows that the structures,shopes and composition are various at different evo lution stages of a typhoon. It is also shown that the new method has an advantage to reveal the overall structure features of a cloud system that is superior to the traditional statistical recognition method.
