用一个包括了湍流热交换、凝结、蒸发、辐射冷却、云量对辐射调节及海水上翻等各种物理过程在内的简单海-气耦合模式,进行了长期的数值积分。结果表明,热带海温异常通过热力过程影响大气的垂直环流,这种效应首先是局地的,以后这种影响会扩展到中纬度,而反过来,大气又对海洋产生动力影响,使海温发生变化。在只考虑上层海洋的情况下,试验表明在这一耦合系统中,存在着短期气候振荡,并且在赤道中太平洋和赤道东太平洋之间大尺度海表温度异常存在着落后相关。
A simple long-term numerical integration was made using a simple sea-air coupling model involving various physical processes such as turbulent heat exchange, condensation, evaporation, radiative cooling, cloud volume radiation regulation, and seawater inversion. The results show that the tropical SST anomaly affects the vertical circulation of the atmosphere through the thermal process, and this effect is firstly localized. Later this effect will extend to mid-latitudes. On the other hand, the atmosphere will have a dynamic impact on the ocean so that the SST Change. In the case of considering only the upper ocean, experiments show that there is a short-term climate oscillation in this coupled system and there is a backward correlation between the large-scale sea surface temperature anomalies in the equatorial Central Pacific and the equatorial Eastern Pacific Ocean.
