摘要

A new parameterization of mixing processes in the upper ocean is tested in a 1/4 degrees resolution global ocean climate model. The parameterization represents the effect of turbulent mixing by unbroken waves as an additional turbulent shear production term in the k-epsilon mixing scheme. The results show that the inclusion of this parameterization has a noticeable effect on ocean climate, particularly in regions of high wave activity such as the Southern Ocean. Inclusion of this process also leads to some reduction in the biases of the simulated climate, including mixed layer depth, compared with available observations.
