本文从理论上探讨了夏季南黄海和东海层化陆架区,在台风作用下强制界面波的基本特性。研究表明,上层强制波受内界面波的影响甚微,具有与正压海强制波同样特性,它导致了一个随台风移行的孤立波,同时派生一个逆向传播的陆架波系。在台风域内跃层下陷导致内界面波时空不连续,形成一个“零波域”随台风移行,但仍有一个内陆架波逆向传播。其振幅随跃层下层水深的增加而增大,下层水深随风速的增大而减小。上层波振幅小于下层内波振幅。
In this paper, the basic characteristics of forced interface wave under the action of typhoon are discussed theoretically on the stratigraphic shelves of the South Yellow Sea and East China Sea in summer. The results show that the upper forced wave has little influence on the inner boundary wave and has the same characteristics as the positive pressure sea-forced wave. It leads to a solitary wave that travels with the typhoon and at the same time derives a reverse-propagating wave system. The dip in the typhoon led to the discontinuity of the internal boundary wave in time and space, forming a “zero-wave-field” that shifted with the typhoon. However, there was still a reverse intrusion of the inland wave. The amplitude increases with the increase of the depth of the lower thermocline, and the depth of the lower layer decreases with the increase of the velocity of the wind. The upper wave amplitude is smaller than the lower wave amplitude.
