赤道地区海洋大气耦合系统中波动的长期演变

天气和气候分析的事实告诉我们,赤道地区不仅存在着天气尺度的扰动,同时也存在着长达数月乃至数年的准周期性振动.这类长周期的振动也出现在海洋运动(如海流和海水温度)中.关于赤道地区天气尺度的扰动,松野(Matsuno)1]等从理论上作过分析.他采用beta平面近似,得到了赤道地区混合罗斯贝(Rossby)重力波等几种波动.

LONG-TERM EVOLUTION OF WAVES IN A COUPLED TMOSPHERE-OCEAN MODEL IN EQUATORIAL REGION

The observational facts show that there exist the quasi-periodic fluctuations with time scales of days as well as months in the atmosphere and ocean in equatorial region.To study these phenomena,a coupled atmosphere-ocean model is developed,in which the mixed process in upper layer of the ocean is considered.The non-adiabatic heating comprises Newton radiative cooling and condesation in the atmosphere and the evaporation from sea surface,upwelling in the mixed layer of ocean and short waves radiation to be mbdulated by cloud.
