印度尼西亚海潮致混合研究现状与展望

印度尼西亚海(简称印尼海)位于热带太平洋和印度洋交汇的海域,是全球最大的内潮生成海域.内潮耗散导致强烈的潮致混合,一方面将温跃层以下的海水卷入上层,降低印尼海海表温度,之后通过海气相互作用产生显著的天气和气候效应;另一方面对穿越印尼海的印度尼西亚贯穿流的物质与能量输运也有着重要影响.自Ar-lindo计划以来,人们对印...

Progress and Prospect on the Study of Tidal Mixing in the Indonesian Seas

The Indonesian Seas, which is located between the tropical Pacific and Indian Ocean, is one of the largest internal tide generation sites in global oceans. The dissipation of internal tides leads to strong tidal mixing, thereby reducing sea surface temperature in the Indonesian Seas and induce significant climate response through active air sea interaction. Moreover, the tidal mixing also plays important roles in regulating the Indonesian Throughflow and related mass and energy transport from the Pacific to the Indian Ocean. Since the Arlindo Project, it is realized that the exceptionally strong tidal mixing in the Indonesian Seas is important for improving the simulation of the ocean circulation in numerical models. However, owing to insufficient in situ measurements of mixing and incomplete tidal mixing parametrization scheme, quantitative analysis on the distribution and variability of tidal mixing in the Indonesian Seas and sufficient consideration of tidal mixing in ocean and climate models are yet to be resoved. In this paper, the latest progress on the tidal mixing in the Indonesian Seas and its application in ocean and climate models are reviewed and the prospect of this topic is also proposed.
