Coupled atmosphere-ocean model has developed in various agencies. Warner et al. developed COAWST model using the atmosphere model WRF, the ocean model ROMS and the wave model SWAN. Though there are several studies with coupled model, the coupling model using WRF has not been developed in Japan and there is no research analyzing the changes in ocean current and water temperature in detail. In this study targeting Typhoon Melor (2009), several calculations that changed the coupling condition were carried out, and it is estimated the meteorologic and oceanic field at Tanabe bay in Wakayama. The results show that the wave energy dissipation by the wave model is effective in the change of ocean current and the thermal feedback by the atmospheric model is effective in the change of water temperature due to the typhoon passage.
