中文摘要:
      文中利用简化的海-气耦合模式及低谱方法和多平衡态理论,讨论了南亚地区冬夏季风与邻近海域海温季节变化之间的相互影响。结果表明:(1)冬季风较强时,冬季海温较低,翌年夏季海温也较低;反之亦然。夏季风较强时,夏季海温较高;反之亦然。夏季风强弱对冬季海温的影响不明显。(2)海-气相互作用使南亚冬季风和夏季风都加强。海温经向梯度使冬季风加强,而夏季风减弱。
英文摘要:
      From view point of airsea interaction, in South Asia, winter and summer monsoon affect ocean current and sea temperature of neighborhood sea area, and ocean (especially ocean inclined temperature layer) also affects monsoon by redist ributing heat flux and sea temperature. So it is significant to research South Asianai-rsea interaction by dynamics method for underst anding deeply the strongness or weakness of winter and summer monsoon as well as the mechanism of their transition. Nonlinear sea temperature equations and equator balance model were used in this paper. Airsea interaction was introduced to the sea temperature equations, thus an ocean-atmospheric coupled model was made. The model contained two physical process:different imposed heat of land and ocean to at mosphere is the basic drive of monsoon; the distributing of sea temperature was changed by the wind blow flow of South Asian monsoon. This model is simplified to be the truncated spectrum model by low-order spectral method, which was easy to be discussed. Multi equilibrium states and stability theory were used to discuss that winter and summer monsoon in South Asia affect sea temperature seasonal change of neighboring sea area respectively, and to discuss airsea interaction and sea temperature long it udinal grads had an effect on monsoon.
