Characteristics of Sea-Atmosphere Coupling Resolution between Different Frequencies
|
Abstract:
A simple coupled ocean-atmosphere model,in which,long wave approximation is used,the heating of ocean to the atmosphere uses local thermal equilibrium,is used to study the characterstics of ocean-atmosphere coupling resolutions In the coupled model,steady-state and unsteady-state atmosphere model are used The results are following In the unsteady-state atmosphere model,the role of interaction between atmosphere Kelvin waves and ocean Rossby waves and between atmosphere Rossby waves and ocean Kelvin waves is positive feedback,and the role of interaction between atmosphere and ocean Kelvin waves and between atmosphere and ocean Rossby waves is negative feedback The numerical tests show that the numerical solusions are similar to observations in the unsteady-state atmosphere model case In the steady-state atmosphere model case,the ocean-atmosohere interaction of seprate waves between ocean and atmosphere makes the energy of perturbations unlimitedly increase; the numerical solonsions are not similar to observations
