项目摘要
Ocean general circulation models have been improved dramatically in recent years ; we are now able to compare directly results from models with in situ observations. In the present study we have accelerated this movement in close cooperation with international colleagues who show strong interests in the western boundary currents in the western Pacific. Our final goal is to provide high-resolution ocean models for practical purposes such as daily ocean current prediction. On the basis of last two-years' international cooperative research, we have been successful in achieving several important scientific findings as well as improvement of ocean models. First, we have demonstrated the role of the joint effect of baroclinicity and bottom relief on the Kuroshio transport variations. Secondly, we have discovered and named <the Luzon Undercurrent> both in models and in situ observations obtained during US-PRC WOCE cruises. Thirdly, we have studied in full depth the seasonal variations of the Indonesian Throughflow and published a special issue of J.Geophys.Res. We have distributed 50 reprint volumes all over the world. Fourthly, we have analyzed Russian data for the formation of lenses composed of the intermediate water. Fifthly, based on the model results, we have found the Sri Lanka Dome and Bay of Bengal Dome in the Indian Ocean and confirmed the existence by the new Levitus data as well as the TOPEX/POSEIDON satellite altimetry data. In addition, we have checked the model performance by comparing surface drifter data and model variability particulary for synoptic scale phenomena of the Kuroshio. It has turned out that the model variability is still weaker than reality. Therefore, it is necessary to introduce further high-resolution models with improved sub-grid scale parameterization. We are planning to do this on the basis of the present accomplishment.
近年来,海洋环流模式得到了极大的改进;我们现在能够直接将模式结果与现场观测结果进行比较。在本研究中,我们与对西太平洋西部边界流表现出浓厚兴趣的国际同事密切合作,加速了这一运动。我们的最终目标是提供高分辨率的海洋模型,用于日常洋流预测等实用目的。在过去两年国际合作研究的基础上,我们成功地取得了几项重要的科学发现,并改进了海洋模型。首先,我们论证了斜压性和海底地形起伏的联合作用对黑潮输送变化的影响。第二,我们在<the Luzon Undercurrent>中美WOCE巡航期间获得的模型和原位观测中发现并命名了它们。第三,我们深入研究了印度尼西亚海流的季节变化,并出版了《地球物理学研究杂志》专刊,在全世界发行了50册重印本。第四,我们分析了俄罗斯关于中间水形成透镜体的资料。第五,根据模式结果,我们在印度洋发现了斯里兰卡穹和孟加拉湾穹,并利用新的Levitus资料和TOPEX/POSEIDON卫星测高资料证实了它们的存在。此外,我们还通过比较海面漂流资料和模式变率,特别是黑潮天气尺度现象,检验了模式的性能。事实证明,模型的可变性仍然弱于现实。因此,有必要进一步引入具有改进的次网格尺度参数化的高分辨率模式。我们计划在现有成就的基础上这样做。
