摘要
根据数字化气象卫星资料的特点，设计了对卫星云图进行自动分类识别的动态聚类算法。利用ＧＭＳ５的１０５～１１５μｍ和０５５～０９μｍ两个通道的资料，采用迭代自组织的数据分析算法（ＩＳＯＤＡＴＡ算法）对云图进行了分类试验。
On the basis of the characteristics of satellite cloud picture, this paper gives one automatic classification method of satellite cloud image:Iterative Self Organizing Data Analysis Techniques Algorithm (ISODATA). The satellite data used are from two channels of GMS 5. One channel is of 10.5-11.5 μm, the other is of 0.55-0.9 μm. The calculation shows:while the cloud image is classified as surface, high cloud, middle and low cloud, deep cloud, good results have been achieved.
