| 摘 要： | 考虑海气界面附近大气边界层内海浪充分发展情况下的海气动量交换．根据Ｄｏｎｅｌａｎ（１９８２）的观点建立海气界面模型，采用ｋ ε模式以计算湍流流场．所得流场结构包括风速、湍流动能、湍能耗散及湍流粘性系数等都较合理；计算的海面阻力系数ＣＤ在中等风速时与实测结果符合良好．

| Abstract: | Turbulent air flow over well-developed wind waves in air-sea boundary layer is numerically simulated without considering wave breaking. Wind wave model is constructed according to the Donelan's idea. We have adopted the k - ε model to calculate the turbulent flow. The results of drag coefficient and turbulence characteristics agree well with observations. |

| Keywords: | drag coefficient wind waves k - ε turbulent model air-sea interaction |
