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).

南中国海位于东南亚，是世界上最大的边际热带海洋，是印度太平洋暖游泳池的一部分。该地区对南亚具有重要的经济和环境意义，南亚几乎是世界人口的近10％的所在地，依赖南中国海的粮食和生计。从2019财年到2022财年，这个为期三年的研究项目的主题是南中国海冬季冷舌（CT）的过程和影响及其相关的大气循环。这项研究具有两个关键目标，要研究（1）CT背后的大气和海洋过程，以及（2）CT海面温度的大气影响。该研究是使用日本海洋 - 地球科学技术机构（JAMSTEC）进行的，对气候研究机构的攀岩模型和气候研究中心（CCRS）（CCRS）的区域尺度尺度模型进行了研究。使用这些模型进行了几项敏感性实验，并分析了结果。该项目已通过一次国内会议（即日本海洋学会会议），两个国际会议（即亚洲 - 科学学会）（即两次同伴审查的国际杂志（即气候杂志）（I.E。
