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，也是印太暖池的一部分。该地区对东南亚具有重要的经济和环境意义，世界上近10%的人口依靠南中国海获得粮食和生计。本项目为期3年（2019 - 2022财年），研究主题为：从2019财年开始，南海冬季冷舌（CT）及其相关大气环流的过程和影响。该研究有两个主要目的，即调查(1)CT背后的大气和海洋过程以及(2)大气对CT海面温度的影响。该研究使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进行。利用这些模型进行了多次灵敏度实验，并对实验结果进行了分析。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）和两份同行评议的国际期刊出版物（即《气候杂志》和《皇家气象学会季刊》）交流了结果。
