假定运动为正压,在西南季风盛行期间,讨论了南海北部陆坡海域的地形Rossby波的非线性相互作用。地形Rossby波非线性相互作用引起上层海水产生垂直运动,致使上层海水热含量重新分市。在那些上层海水热含量迅速增加的地方,对台风发生、发展甚为有利,这与实测资料一致。 Assuming that the movement is a positive pressure, the nonlinear Rossby wave nonlinearities in the northern South China Sea are discussed during the prevalent southwest monsoon. The non-linear interaction of the terrain Rossby waves causes vertical movement of the upper seawater, resulting in the re-entry of the heat content of the upper seawater. Where the heat content of the upper ocean is rapidly increasing, the occurrence and development of typhoons are very favorable, which is consistent with the measured data.
