摘　　要：提出了采用数学形态学与句法模式识别结合，将云系结构与天气系统联系起来的卫星云图计算机分析识别方法。克服了传统的统计识别方法不能很好地反映云系整体性结构的缺陷。对一次台风过程不同阶段云系发展演变特征，实现了计算机分析识别试验。结果显示，在台风发展的不同阶段，云系的结构、形状和组成是不同的。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.
