主 题:Stokes production POM upper mixed layer upwelling
摘 要:A two-dimensional numerical model,which is configured on the basis of Princeton ocean model(POM),is used to study the effect of Stokes production(SP) of the turbulent kinetic energy on a density profile and Ekman transport in an idealized shelf region in *** energy input from SP is parameterized and included into the Mellor-Yamada turbulence closure *** reveal that the intensity of wind-driven upwelling fronts near the sea surface is weakened by the SP-associated turbulent kinetic energy *** vertical eddy viscosity coefficient in the surface boundary layer is enhanced greatly owing to the impact of SP,which decreases the alongshore velocity and changes the distribution of *** addition,the SP-induced mixing easily suppresses the strong stratification and significantly increases the depth of the upper mixed layer(ML) under strong winds.
