A micro-computer 386 based Cloud-motion Wind Inferring System(CWIS)has been developed for the winds from geostationary meteorological satellite images.In this paper,the main structure of the system in connection with the processing method.Preliminary analyses of the experimental data collected randomly from Beijing Satellite Meteorological Center have shown that the system is quite encouraging and the results are in good agreement with the analyses from weather maps and further improvement is possible to the system.It is pointed out that the characteristics of cloud motion winds must be kept in mind when they are used together with conventional wind soundings.
