摘要
热带非稳定波(TIWs)关于赤道的径向不对称是其突出特征之一。本文利用二层半线性海洋模式研究各种不对称背景条件对非稳定波不对称性的影响。结果表明,在大西洋和太平洋上热带非稳定波(TIWs)的不对称性似是由于南赤道流的两个分支和海面温度锋面对于赤道的不对称性,而不是由于北赤道逆流的出现。
Abstract:One of the prominent features of tropical instability waves (TIWs) is their meridional asymmetry about the equator. A linear, 2 -layer ocean model is used to investigate the effect of Yarious asymmetric background states on the symmetry of unstable waves. The results suggest that the asymmetry of TIWs in the Atlantic and Pacific Oceans is likely due to the asymmetry about the equator of the two branches of the South Equatorial Current and of the sea-surface-temperature front, but not to the presence of the North Equatorial Countercurrent.
