Study on surface wave-induced mixing of transport flux residue under typhoon conditions

The transport flux residue of surface waves plays an important role in a variety of ocean phenomena, for example, the change in sea surface temperature (SST) and upper mixed layer profile that were studied in a series of recent papers. In the previous studies, its effect was discussed rigorously and fragmented based on numerical modeling. Here we propose a relatively comprehensive and simplified exposition of the wave transport flux residue, and focus on its influence under typhoon conditions with strong background current. An analogue Reynolds Number is presented for tentative comparison with wave-generated turbulence mixing, especially in the coastal area. Numerical results indicate that both overwhelming dynamical mixing processes can remarkably change the coastal environment, and should not be ignored consciously for further marine hazards assessment.
