| 摘 要： | 用观测海温距平对一个中等分辨率的细网格大气模式和观测 FSU假风应力对全球热带三大洋距平海洋模式分别进行强迫试验。结果表明 :无论是大气模式还是海洋模式均在一定程度上较好地模拟了观测事实 ,热带大西洋的模拟效果好于热带印度洋。对大气模式而言 ,经向风距平的模拟要好于纬向风距平 ,热带大西洋西部好于东部 ,热带印度洋东部好于西部 ,赤道南侧好于北侧。对海洋模式而言 ,热带大西洋模拟最好的区域是赤道中东部 ,对赤道东印度洋的暖事件及偶极子事件年际变率模拟也较好。在此基础上 ,用和海气耦合模式同样的耦合方式将两者耦合起来 ,构成了一个中等复杂程度的全球热带海气耦合模式 ,这是进一步研究全球热带海气相互作用的基础

| Abstract: | An intermediate-level resolution atmosphere model and a global tropical two-layer ocean model are forced by observed SSTA and FSU pseudo-stress anomaly respectively. It is found that the model simulations agree well with the observations to a certain extent. The model simulations in the Atlantic region corresponding to the observations are better than that in the Indian region. The results demonstrate that the simulations of meridional wind anomaly in the atmosphere model are more similar to the observations than the simulations of zonal wind anomaly. The effects of the simulations in the West Atlantic region and in the central-east Indian region are better. It is also indicated that the SSTA's inter-annual variability within the east equatorial Atlantic Ocean and the west equatorial Indian Ocean is simulated very well. The dipole mode events of the equatorial Indian Ocean can be captured very well, too. So a global tropical intermediate coupled model (GICM) can be developed based on the two models described above. |
