主　　题：Langmuir circulations vertical mixing thermocline subsurface temperature non-breaking wave processes 

摘      要：Insufficient vertical mixing in the upper ocean during summer is a common problem of oceanic circulation and climate *** turbulence associated with non-breaking waves is widely believed to effectively solve this *** many studies,non-breaking surface wave processes are attributed to the effects of Langmuir circulations(LCs).In the present work,the influences of LCs on the upper-ocean thermal structure are examined by using one-and three-dimensional ocean circulation,as well as climate,*** results indicated that the effect of vertical mixing enhanced by LCs is limited to the upper *** models evaluated,including those considering LC effects alone and the combined effects of LCs and wave breaking,failed to produce a reasonable summertime thermocline,resulting in a large cold bias in the subsurface ***,while they can slightly reduce the biases of mixed layer depths and sea surface temperatures in models,LCs are insufficient to solve the problem of insufficient vertical ***,restriction of non-breaking surface wave-induced processes in LCs may be questionable.
