| 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（STC）、热带环流圈（TC）、副极地环流圈（SPC）、深层热带环流圈（DTC）和温跃层环流圈（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 of all the North Pacific overturning cells, it has five cells: the subtropical cells (STC), the tropical cell (TC), the subpolar cell (SPC), the deep tropical cell (DTC) and the thermocline cell (THC). The cells are the important leakage of the meridional material and energy exchange. The NPMOC and its variation play an important role in the upper ocean thermohaline structure and the climate change. The structure, and the variability and the variation mechanism of the STC, TC and DTC of the NPMOC are extensively analyzed and the poleward heat transport of the STC has done preliminary analysis. It should be noted that the research on the SPC and THC are still less, and it is unknown the three-dimensional structure and variation mechanism of the two cells. The research of the heat and salt transport of the NPMOC is still at an initial stage. Now little is known about the heat and salt transport characteristics, the variation and the variation mechanism of the cells and these scientific problems need to be further studied. |
