| 摘 要： | 应用漂流浮标,结合卫星高度计资料和示踪粒子法,研究了中国南海中尺度涡的输运能力。从浮标漂流轨迹和对应的流场分布可知在真实海洋中存在涡对物质的输运,陷入反气旋涡的漂流浮标跟随涡旋顺时针打转4圈,以圆弧形轨迹运动至海南岛以东。进一步通过示踪粒子法进行长期模拟得出涡内物质会以和涡相同的旋转方向旋转前进,在忽略水平方向上的混合对示踪粒子轨迹影响的情况下,在第55天,93%的质点(153个)将跟随涡旋运动,7%的质点(11个)会在中途与涡旋分离,运动中涡会不断把内部物质甩向涡的外缘,质点会从涡最边缘速度由大转小处脱离涡旋,但是大多数质点会跟随涡旋在其边缘以圆弧形轨迹向前运动,并最终稳定在涡旋的最边缘。

| Abstract: | The transportation capacity of South China Sea mesoscale eddy was studied using Drifter buoys, combined with satellite altimeter data and tracer particles method. Both Drifter buoy data and the flow field showed the existence of the eddy transportation in the real ocean. The Drifter buoy moved into the anticyclonic eddy, and then followed the eddy to make 4 turns, in the end, the Drifter buoy moved towards the east of Hainan Island with arc-shaped trajectory. From the long-term simulation results using tracer particles method, we learned the particles in the eddy moved forwards in the same rotational direction, 93% particles(153) followed the eddy motion, and 7% particles(11) were separated from the eddy in midway. The eddy throwed the particles from inside to edge of eddy, some particles were out of the eddy from the place of the eddy edge, in which the speed turned from large to small. But most particles followed the edge of eddy with arc-shaped trajectory; finally, they were stabled at the very edge of the eddy. |
