This report deals with a construction of the support system for determinations of the sea state by using image information data transmitted from the Geostationary Meteorological Satellite (GMS). The support system consists of three basic software tools. The tool 1 presents digital techniques for the image analysis of meteorogical information data from GMS. The tool 2 is composed of a simple approach to forecasting wind velocity system based upon a weather chart referring to meteorological data and of a utility of forecasting wind waves by using Wilson's approach based upon the SMB method. The tool 3 presents a digital simulation technique of random waves by using Walsh Tranform algorithm. The technique can be applied to a rendering method in numerical random simulations for a variety of marine environments (wind, wind waves etc.). A series of numerical computations are executed for a sea state in the North Pacific Ocean withn a winter day by using the present support system. It is confirmed that the support software tools is effective in simulations of wind and wind waves in an area of sea within an optional day, and that those tools reduce hugely the computer execution time requirement.
