All these results confirm the important of wind in meridional circulation and heat transport . based on mom2 model , a rectangular basin model with ideal w ind stress and other ideal conditions is designed to study the main processes and dynamical mechanism in setting the depth of cross - equator flow . the effects of horizontal diffusivity , seasonal variations of 我們還通過全球海洋環(huán)流模式,進一步證實了風(fēng)應(yīng)力的季節(jié)變化在北印度洋熱收支、 sst以及海洋環(huán)流變化中的作用:即包含風(fēng)應(yīng)力的季節(jié)變化將使長期平均的sst降低,海面凈熱通量增加。
