摘      要：The tide-induced mixing plays an important role in the regulation of ocean *** simulation of continental shelf circulation is found to exhibit an unreasonable vertical thermohaline structure without consideration of tide *** this study,we establish a harmonic analyzed parameterization of tide-induced（HAT） mixing,by which means to derive time-depended function of mixing coefficient based on harmonic analysis of the vertical mixing *** employing HAT mixing parameterization scheme,a series of numerical experiments are conducted for the Yellow *** results show that an ocean circulation model with the HAT mixing involved is capable of reproducing the reasonable thermohaline structure of the Yellow Sea Cold Water Mass,similar to structures produced by explicit tidal forcing on the open *** advantage of the HAT method is its faster computation time,compared with models that directly resolve explicit tidal *** HAT parameterization for the tide-induced mixing has potential to improve both the accuracy and efficiency of ocean circulation and climate models.
