台風下における海面抵抗係数の海洋物理環境場への影響

There are a lot of researches about momentum exchanges at sea surface which focus on the relationship between wind speed and roughness. Although such researches continue, none of them has explained the roughness under all sea condition. This study evaluates the impact of bulk formulas including wave information on the typhoon simulation using observed results in ITOP. Air side roughness including wave information makes the heat flux from sea to strengthen and influences the wind profile even in the upper air. Typhoon is not affected the air side roughness. The bulk formulas of sea side roughness and TKE flux which is based on wave information estimate smaller current speed and TKE than the formulas based on wind.
