南海上层海洋对台风的响应研究

The typhoon is one of the most importent coupled form of air-sea interaction. It has important scientific significance and practical application value to carry out the research process of the upper ocean response to typhoon, for the accurate prediction of typhoon track and intensity, as well as an in-depth understanding of the biochemical and physical process coupling in the upper ocean and lower atmosphere..The project will be based on the field observation and data analysis，focus on the study of 3D structure response of upper ocean caused by the typhoon, to determine the wind energy input to the ocean and its transport and dissipation in the upper ocean, the relationship between the intensity, the thickness of thermocline, to reveal the driving mechanisms of upper ocean cooling, as well as the role of the near-inertial turbulent mixing on the energy and mass exchange across the thermocline. To carry out these efforts aim to lay the foundation for further studying of the air-sea coupling interaction.

台风是最具毁灭性的自然灾害之一。开展台风过程上层海洋的响应研究，对于准确地预测台风路径和强度，深入了解上层海洋-低层大气生物地球化学与物理过程耦合研究具有重要的科学意义和实际应用价值。.本项目将基于现场观测和资料分析相结合的研究方法，研究台风过境引起的上层海洋的三维响应，确定风输入海洋能量在上层海洋的传播、耗散及与温跃层的强度、厚度之间的关系，揭示上层海洋降温驱动机制，阐明近惯性湍流混合在跨跃层能量和物质交换过程中的作用，为深入开展海气耦合相互作用研究奠定基础。
