摘要:

北太平洋经向翻转环流是北太平洋所有经向翻转环流圈的总称, 目前它拥有五个环流圈, 即副热带环流圈(the subtropical cell, STC)、热带环流圈(the tropical cell, TC)、副极地环流圈(the subpolar cell,SPC)、深层热带环流圈(the deep tropical cell, DTC)和温跃层环流圈(the thermohaline cell, THC)。这些环流圈是北太平洋经向物质和能量交换的重要通道, 它们的变化对海洋上层热盐结构和气候变化皆有重要影响。迄今, 人们已对STC、TC和DTC的结构形态、变化特征与机理开展了广泛而深入的研究, 并对STC的极向热输送特征也做了一些初步分析。但应指出的是, 关于SPC和THC的研究仍较少, 迄今尚不清楚这两个环流圈的三维结构和变异机理; 而且, 对北太平洋经向翻转环流的热盐输送研究尚处于起步阶段,目前对各环流圈的热盐输送特征、变化规律和变异机理仍知之甚少, 这些科学问题亟待深入研究。

Abstract:

The North Pacific meridional overturning circulation (NPMOC) is the general name given to the five North Pacific overturning cells: the subtropical cell (STC), the tropical cell (TC), the subpolar cell (SPC), the deep tropical cell (DTC), and the thermocline cell (THC). These cells are important for the leakage of meridional material and energy exchange. The NPMOC and its variation play an important role in the upper ocean thermohaline structure and climate change. The structure of the STC, TC, and DTC, and the level and mechanism of variation in these are currently being extensively analyzed, and a preliminary analysis of poleward heat transport by the STC has been completed. Less research has been undertaken on the SPC and THC; however, the three-dimensional structure and mechanism of variation remains unknown. In addition, research into heat and salt transport by the NPMOC is still at an initial stage, with little knowledge at present about the characteristics and the level and mechanism of variation within each cell. Therefore, this requires further investigation in the future.
