Numerical Experiments on Strong Vertical Mixing under Strong Winds in the Coastal Zone

There are several bulk flux models for an ocean surface boundary layer, such as surface roughness and TKE fluxes at the ocean surface. However, these bulk flux models have not been calibrated in detail.The validation for the parameterization of bulk flux models is carried out analyzing correlation of temperature and velocity vertical distributions between numerical results and observed data. The numerical experiments were conducted during the Typhoon Melor in 2009 at Tanabe Bay, Wakayama Prefecture, Japan. It was found that the parameterization for the TKE flux has significant influences on temperature and velocity in the nearshore region.
