摘要	<正>This study uses a large eddy simulation(LES) model to investigate the turbulence processes in the ocean surface boundary layer at Zhangzi Island offshore.Field measurements at Zhangzi Island(39°N,122°E) during July 2009 are used to drive the LES model.The LES results capture a clear diurnal cycle in the oceanic turbulence boundary layer.The process of the heat penetration and heat distribution characteristics are analyzed through the heat ilux results from the LES and their differences between two diurnal cycles are discussed as well.Energy balance and other dynamics are investigated which show that the tide-induced shear production is the main source of the turbulence energy that balanced dissipation.Momentum ilux near the surface shows better agreement with atmospheric data computed by the eddy correlation method than those computed by bulk formula.
