南黄海非线性内波的数值模拟研究(2)——内潮的非线性演变
A Numerical Study of Nonlinear Internal Waves in the South Yellow Sea (2): Nonlinear Evolution of Internal Tidal Wave
摘要
Abstract
Following the previous work, in this paper the reflection and nonlinear evolution of semidiurnal internal tidal wave for the first mode from Station A (34°4’N, 125°6’E) and Station B (36°34’N, 123°51'E) in a westward, southwestward and northwestward direction respectively is modeling, by using the generalized KdV model (GKdV model for short) for continuous stratified ocean, in which the different impact between background barotropic ebb and flood current is considered.The results of modeling show that, the main reason that internal solitary waves are collecting in the south of the South Yellow Sea and seldom existing in the north of the South Yellow Sea is the impact of powerful background baroclinic circulation and very strong background barotropic current in the south of the South Yellow Sea, and on the flood (relative to the west coast of Korea peninsula) the directions of the two currents are the same basically, otherwise the two currents are weak in the north of the South Yellow Sea.In addition, owing to the impact of very strong background barotropic current of 0.75 m/s, the semidiurnal internal tidal wave is not stable from Station A in a northwestward direction.关键词
