简单热带海气耦合模型中的缓慢扰动Ⅰ:对称和反对称于赤道的运动
SYMETRIC AND ANTISYMETRIC SLOW DISTURBANCES IN SIMPLE AIR-SEA COUPLED MODEL IN THE TROPICS

摘要: 文中讨论了在局地热平衡情况下简单模式中的热带海气耦合扰动,指出参数KH,KS和α决定着耦合扰动性质,并研究了使用抛物线柱函数展开时所截项数多寡对耦合扰动性质的影响以及对称和反对称于赤道的耦合扰动特征。Abstract: Slow tropical disturbances in a simple air-sea coupled model are investigated in the local thermal equilibrium case.The results show that the coupled parameter KHKS and the scale parameter restrict the feature of the tropical air-sea coupled system and the coupled disturbances and the characteristics of the coupled disturbances also sensitively depend on the value of n at which the Weber functions Dn(y) are truncated.
