Using the FVCOM-SWAVE coupled regional ocean model,a numerical simulation and comparative analysis were performed for the wind wave effect on the air-sea heat and momentum fluxes in the Yellow Sea during the typical cold wave processes.In order to learn the basic features of the air-sea heat and momentum fluxes in the Yellow Sea,a statistical analysis by air and sea reanalysis data of CFSR(Climate Forecast System Reanalysis,US) were performed for a 5-year duration from 2009 to 2013.The statistical results showed that the air-sea heat and momentum flux exchanges were impacted by the sea surface wind,difference between air-sea temperature,ocean currents,and so on.The fluxes were stronger during the cold season from November to March,while the wave impact was more significant in autumn-winter than in spring-summer,due to the weak ocean currents during the cold season.In the cold season the heat fluxes from between the sea and air were also remarkable,as the air-sea temperature difference and SST grads between latitudes were larger and resulted in an unstable surface environment.The variables of the coastal station comparison showed that the south station faced a wider open sea with a wave height of about 20% higher than the north coastal station,while the south fluxes were also stronger than in the north part.The two typical cold wave events in the cold season were numerically simulated,in which the cold mass paths of invading the Yellow Sea moved from the north and west.The results showed that the air-sea heat and momentum flux exchange became significantly stronger during the cold wave processes,with the momentum flux increasing by about 1-4 times and the heat flux increase 1-6 times over the maximum average values in the cold season.The simulation results also showed that the air-sea heat and momentum flux exchange exhibited obvious differences,due to the different paths and intensity between the two typical cold waves.The heat and momentum flux responses were more intense in the north path cold wave process,with the momentum flux being about 1/4 times stronger than that in the west path cold wave,and the heat flux being 1/2 times stronger.The cold wave path affected the large value distribution of the fluxes.When the wind waves were coupled into the model,the air-sea heat and momentum flux exchanges were enhanced:the height of wind waves increased by 1.5 times,the maximum value of the momentum flux increased by about 2 times,and the heat flux increased by 10-160 W/m².When the height of the wind waves was reduced by 0.5 times,the maximum value of the momentum flux was reduced by about 40%,and the heat flux decreased by about 10-55 W/m².The wind wave provided an important contribution to the air-sea heat and momentum flux features and distribution.
