摘要
热带太平洋—印度洋洋际交换(简称洋际交换)主要通过太平洋—印度洋贯穿流实现,包括印尼贯穿流,不仅是印太洋盆间重要的质量、动量和能量通道,也是太平洋和印度洋之间气候异常信号传播的"海洋信号通道",还是大西洋深层水体进行表层补偿从而使大洋传送带闭合的关键环节,因此在全球海洋和气候系统中占有重要地位.国内外对洋际交换海域环流和气候的研究极其重视,自20世纪90年代以来,来自不同国家的学者开始开展观测研究.我国学者2007年起在洋际交换的主要海峡通道、源区及出流海域开展现场观测,成为国际上洋际交换观测的主要力量.以国内外学者基于这些观测资料取得的科学认识为主线,围绕洋际交换的多尺度变化、跨尺度和跨海盆相互作用,以及对太平洋和印度洋主要气候模态的调制作用4个方面,对其研究现状、主要进展以及亟待解决的关键科学问题进行梳理,同时,对未来5～10年的攻关重点与目标进行了展望.
Abstract
Inter-ocean exchange between the tropical Pacific and the Indian Ocean,which relies on throughflow from the Pacific to the Indian Ocean,serves not only as a crucial conduit for the exchange of mass,momentum,and energy between the Indo-Pacific basins,but also as an oceanic channel for the propagation of climate anomalies between the Pacific and Indian Oceans.In addition,it plays a key role in the closure of the Great Ocean conveyor belt by facilitating the compensation of surface waters in the deep Atlantic.Therefore,interocean exchange is a pivotal component of global ocean and climate systems.It has been recognized as one of the most important academic hotspots for ocean circulation in interocean change regions and their related climates.Since the 1990s,international cooperative actions have been conducted,focusing on the observation of inter-ocean exchange.Starting in 2007,Chinese researchers have conducted observations in the main strait and channels of interocean exchange regions by collaborating with Indonesian researchers.Currently,they have established the largest on-site array for the synchronous observation of interocean exchange.The array covers the key inflow,throughflow,and outflow regions.This paper reviews the major progress and open issues of inter-ocean exchange from four aspects:① multiscale variations of inter-ocean exchange,② cross-scale and ③ cross-basin interactions,and ④ modulation of the primary climate modes of the Pacific and Indian Oceans.The prospects of the key research goals for the next five to ten years are also outlined.
