Does ocean surface wave play a role in climate system? (Weidong Yu) ȯɽ�� :
A question how the ocean surface wave affects the atmospheric general circulation is addressed using an AGCM (LMD model) coupled to an ocean surface wave model (WAM model). A comparison of 10-yr integration between the coupled LMD-WAM run and the control LMD run shows that the mean atmospheric general circulation has been significantly altered both in dynamic and thermal aspects. The atmosphere temperature becomes warmer up to three degree between middle and upper layer and the wind speed is reduced, especially between lower and middle layer. Also the geopotential height field exhibits systematic changes patterns at all layers. Furthermore, the transient eddy of kinetics decreases in coupled run. With reference to ERA data, the coupled model manifests much advantage over control run. This maybe implies that the air-sea flux will be better represented by this kind of dynamic description of sea surface state in coupled GCM, which serves to restrain the troublesome climate drift.
