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.
