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).

位于东南亚的南中国海是世界上最大的边缘热带海域，是印度-太平洋暖池的一部分。该地区对东南亚地区具有重要的经济和环境意义，东南亚人口占世界人口的近10%，依赖南中国海提供食物和生计。2019年至2022年为期3年的研究项目的主题是2019年开始的南海中国冬季冷舌(CT)及其相关大气环流的过程和影响。利用日本海洋地球科学技术厅的S耦合气候模式和新加坡气候研究中心的S区域尺度大气模式研究了CT海面温度对大气的影响。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》)公布结果。
