shows the radial direction change of the time and direction averaged wind speed, friction velocity, sensible and latent heat flux. Oo estimated small wind speed due to large friction velocity. Heat flux is calculated mainly the temperature difference between atmosphere and ocean. Three bulk formulas depending on wave had the peak sensible and latent heat flux of the same degree. Oo estimated the peak value at closer to a center of the typhoon. Figure 6 shows the relation between wind speeds and drag coefficient within a radius of 200 kilometers. The drag coefficient of Oo is large in more than 25 m/s. The bulk formulas depending on wave has larger drag coefficient than the formula depending on wind speed in more than 35 m/s. These relations are equal to the relation of the friction velocity in figure 5. Figure7 shows the radial directiondepth distribution of the direction averaged current velocity and TKE, and differences from the result of bulk formula depending wind speed. The distributions of the surface current velocity are same as the

There are many researches and development for the coupled atmosphere, ocean and wave model due to the improvement of the models. On the other hand, the vigorous observations for the momentum transport between the atmosphere and ocean were carried out due to reconsider the bulk formulas for coupling model. A lot of formulas depending on the wind spe...

The Western North Pacific (WNP) is the most favorable area in the world for the generation of tropical cyclones (TCs). As the most intense weather system, TCs play an important role in the change of ocean environment in the WNP. Based on many investigations published in the literature, we obtained a collective and systematic understanding of the in...
