项目摘要

Located in the Southeast Asia, the South China Sea is the world’s largest marginal tropical sea and is part of the Indo-Pacific warm pool. This region has important economic and environmental significances for the Southeast Asia, which is home to nearly 10% of the world’s population that depends on the South China Sea for food and livelihoods. The theme of this 3-year research project from FY2019 to FY2022 is on the processes and impacts of the South China Sea winter cold tongue (CT) and its associated atmospheric circulation starting from FY2019. The research has two key aims, which are to investigate (1) atmospheric and oceanic processes behind the CT and (2) atmospheric impact of the CT sea surface temperatures.The research was performed using Japan Agency for Marine-Earth Science and Technology (JAMSTEC)’s coupled climate model and Center for Climate Research Singapore (CCRS)’s regional scale atmospheric model. Several sensitivity experiments were performed using those models and their results were analyzed.The project has culminated with the communications of results via one domestic conference (i.e. The Oceanographic Society of Japan meeting), two international conferences (i.e. Asia-Oceania Geoscience Society meetings) and two peer reviewed international journal publications (i.e. Journal of Climate and Quarterly Journal of Royal Meteorological Society).

南海位于东南亚，是世界上最大的热带边缘海，也是印度洋-太平洋暖池的一部分。该地区对东南亚具有重要的经济和环境意义，东南亚拥有世界上近10%的人口，他们依靠南中国海获得食物和生计。该研究项目为期三年，由2019财政年度至2022财政年度，主题为2019财政年度开始的南海冬季冷舌（CT）及其相关大气环流的过程和影响。本研究利用日本海洋地球科学技术机构（JAMSTEC）的耦合气候模式和新加坡气候研究中心（CCRS）的区域尺度大气模式，研究了CT背后的大气和海洋过程以及CT海表温度对大气的影响。利用这些模型进行了几次敏感性试验并分析了试验结果，该项目最终通过一次国内会议（即日本海洋学会会议）、两次国际会议（即亚洲-大洋洲地球科学学会会议）和两份同行评审的国际期刊出版物（即气候杂志和皇家气象学会季刊）交流了结果。
