Abstract: This paper tries to analyze the relationship between China Sea wind field and El Nino by using CCMP (Cross-Calibrated,Multi-Platform) wind field,and to take advantage of the CCMP wind field to drive WAVEWATCH-Ⅲ wave model to simulate the China Sea wave field,and explore the intrinsic link between China Sea waves field and El Nino,which aiming to use El Nino indicators to serve long-term forecast and disaster prevention and reduction in the China Sea wave fields and wind field.Results show that the China Sea wind field and wave field are closely related to nino3 index:①A comparison of China Sea wind fields,wave field with nino3 index over the same period has been made,with a lag of 14 months for wind field and wave field,nino3 index shows significant negative correlation to them,especially with a lag of 2 months for wind field and wave field,nino3 index shows strongest negative correlation to them.With a lag of 710 months for the wave field and wind field,nino3 index shows positive correlation to them,especially with a lag of 8 months,while nino3 index shows the strongest positive correlation to them.② During 1988 to 1997,1999 to 2009,the trend of wind field and wave field with lagged 8 months show very good consistency with nino3 index.③ Nino3 index,China Sea wave field,wind field have the significant and regular periods of 5.876.29 months,11.0013.54 months.④The mutation period of nino3 index is the late 1980s,July in 1999 to November in 2000,20052009.The mutation period of wind field is completely consistent with that of wave field,which is from November 2000 to May 2001,and this mutation may be caused by that of SST in nino3 area.
