| 摘 要： | 利用日本气象厅"best track data"热带气旋数据、QuikSCAT(Quick Scatterometer)卫星风场数据和SCUD(Surface Currents from a Diagnostic model)表层流场数据,估算了热带气旋对南海表层流和波浪的能量输入。结果显示,由于热带气旋基本都位于南海中北部,热带气旋对表层流和波浪的能量输入也集中在南海中北部;能量输入最大的月份均在8月和11月,而在9月对总能量输入贡献最大。5～12月,热带气旋对南海表层流的能量输入为1.26GW,占风对表层流总能量输入的9.87%;热带气旋对表层波浪的能量输入为11.60GW,占风对表层波浪总能量输入的5.42%。如果只考虑10°N以北区域,则热带气旋对表层流和波浪能量输入的贡献分别达到11.29%和6.87%。

| Abstract: | Using the tropical cyclone dataset named "best track data",QuikSCAT wind dataset and SCUD(Surface Currents from a Diagnostic Model) dataset,we studied the wind energy input to the surface currents and waves induced by the tropical cyclones in the South China Sea(SCS).The results show that wind energy input induced by the tropical cyclones concentrate in the northern SCS,due to nearly all tropical cyclones are located at the northern SCS.Both the wind energy input to the surface currents and waves induced by the tropical cyclones are more larger in August and November,but the contribution of the tropical cyclones to the total wind energy input to the surface currents and waves reached the largest in September.From May to December,the wind energy input to the surface currents induced by the tropical cyclones is about 1.26 GW,account for 9.87% of the total wind energy input to the surface currents;and the wind energy input to the surface waves induced by the tropical cyclones is about 11.60 GW,account for 5.42% of the total wind energy input to the surface currents.If only considering the area north of 10°N,the contribution of the tropical cyclones to the total wind energy input to surface currents and waves increase to 11.29% and 6.87% respectively. |
