Intending to meet the requirements in future Global Atomospheric Research Program, a method for obtaining wind vectors from the cloud motion in satellite Pictures was investigated.The acquisition of the precise wind vectors from the pictures taken by the meteorological geosynchronous satellite is based on the premise that clouds are automatically extracted from the picture data to determine the correlation areas in a foating mode so as to take the extracted clouds as their centers.The double thresholding method was developed to extract small clouds as well as the boundaries of even large clouds. A second premise is that correlation areas from the next picture are also selected in a foating mode by applying prediction. It was found that the above method gave two to three times better accuracy than the prior fixed area matching method.Thus the usefulness of the picture processing system by this method, using three sequential pictures,was implied.
