Abstract

A proxy of the Indonesian Throughflow (ITF) transport, developed using in situ hydrographic measurements along with assimilations, shows a significant strengthening trend during the past decade. This trend is due to a freshening and subsequent increase in the halosteric component of the ITF transport associated with enhanced rainfall over the Maritime Continent over the same period. The strengthening of the ITF transport leads to a significant change in heat and freshwater exchange between the Pacific and Indian Oceans and contributes to the warming and freshening of the eastern Indian Ocean. The combined effect of the ITF transport of mass and freshwater along with tropical rainfall plays a very important role in the climate system.

摘要

利用现场水文测量数据并结合同化技术得出的印度尼西亚贯穿流（ITF）输运量的一个代理数据显示，在过去十年中，该输运量呈现出显著的增强趋势。这一趋势归因于同期内，与海洋大陆降水增加相关联的ITF输运量的比容盐度分量变淡并随后增加。ITF输运量的增强导致太平洋和印度洋之间的热量和淡水交换发生显著变化，并促使印度洋东部变暖且变淡。ITF的质量和淡水输运量与热带降雨的综合作用在气候系统中起着非常重要的作用。
