We devised a method for the estimation of sea surface winds over coastal area and inland sea. The method is constructed by the combination of open ocean wind model and local wind model. Cardone's boundary layer model and Sherman's MATHEW model are adopted as the respective wind models. The method is applied to Tokyo Bay. Estimated winds are compared with the observations at Tokyo light house, Keiyo sea berth and Chiba marine observation tower. The estimations agree reasonably well with the observations. Based on the result, behavior of heavy winds associated with Typhoon 9119 over the Inland Sea is analysed by use of the method. The results will be used in the analysis of distractive wind waves of Typhoon 9119 in the Inland Sea.
