Sea Wind Fields Generation Using Typhoon Bogus Scheme and Satellite Images

Abstract

The available global meteorological data from atmospheric general circulation models (AGCMs) are used for short-term (hours or a few days), medium-range (up to 10 days), and seasonal forecasts and also for long-term climatic purposes. Depending on the range, AGCMs are coupled to different models for waves or ocean circulation. However, extreme weather events simulated by global AGCMs, such as tropical cyclones, typhoons, hurricanes and gales, are not appropriate for simulation of abnormal storm waves and extreme wave analysis. Therefore, we introduced a bogussing scheme (Low-Nam and Davis, 2001) to improve our estimation of meteorological conditions such as wind and pressure field by resolving the developed low pressure more accurately in a mesoscale model with typhoon parameters.
