摘要
用数值方法对热带海气耦合波进行了研究。结果表明,当大气和海洋中都滤去赤道Kelvin波,而只存在向西传的赤道Rossby波时,由于海气相互作用,同样可以使扰动向东传播。扰动向东传的临界波长与海气相互作用的强度有关。当海气相互作用越强时,向东传的扰动分量越大。数值试验的结果与理论分析所得的结果一致。
By the numerical method,the tropical air-sea interaction waves are studied.The results show that when the Kelvin waves are filtered out and only the equatorialRossby waves are reserved both in the atmosphere and in the ocean,the disturbances canalso propagate eastward because of the air-sea interaction. The critical wavelength ofthe eastward propagating waves is related to the intensity of the air-sea interaction,thestronger the air-sea interaction, the larger the eastward propagating components of theair-sea interaction waves. The results of the numerical experiments are in good agree-ment with those by theoretical analysis.
