中文摘要: 对红外卫星云图进行图象处理之后，对MCS的边界廓线进行傅里叶展开，求得其形态特征。利用形态特征的保守性，得到MCS的移动矢。以此对MCS的移动作外推预报，结果表明，准确率比目测判别要高。
中文关键词: MCS，形态特征，外推预报
Abstract:After satellite image was processed,Fourier expansion was made for MCS's boundary line.Using the conservatism of morphology feature,the translation vector was obtained and the extrapolation forecast was given The result shows that the accuracy is higher than visual observation.
