The statistical characteristics of typically westward and northward 35 tropical lows,tropical storms,strong tropical storms and typhoons over the northwest Pacific during the period of July ～ November,1986～ 1996 were investigated through the data of meteorological and wave fields in meteorological report of ships. It was demonstrated that the distribution patterns of the wind field and wave field caused by typhoon were obviously different for various intensity of typhoon and associated various synoptic pattern. The statistical model of the wind field and wave field caused by typhoon was established based on the present analysis. This model is of the practical value for ship to avoid the unfavorable weather and oceanic conditions and is also meaningful to do better oceanic and meteorological routing service.
