0118363Matano/OSUThe purpose of the is project is to use numerical modeling to examine the routes by which the upper return flow in the South Atlantic carries heat and salt across the basin and the role that mesoscale eddies play in this transport. First, diagnostic studies of existing global and Atlantic simulations will be made. This will be followed by process studies designed to test hypotheses about the paths of Pacific and Indian Ocean upper thermocline waters through the South Atlantic to the tropics. The project's broad goals are: (1) to understand how changes in magnitude of southern sources of water, the Antarctic Circumpolar Current and the Agulhas Current, affect the magnitude and relative composition of South Atlantic upper ocean export to the tropics, (2) to understand the mechanisms that regulate the mean circulation and variability of the subtropical gyre and their linkage to interocean exchanges, and (3) to determine the sensitivity of the South Atlantic circulation to changes in wind forcing in the southern hemisphere.

IS项目的0118363MATANO/OSUTHE的目的是使用数值建模来检查南大西洋的上部回流流在整个盆地中携带热和盐的途径以及中尺度涡流在该运输中起的作用。 首先，将对现有的全球和大西洋模拟进行诊断研究。 随后将进行过程研究，旨在测试有关太平洋和印度洋上部热跃层水域穿过南大西洋到热带地区的道路的假设。 该项目的广泛目标是：（1）了解南大西洋上海的大小和相对组成如何影响到热带地区的南大西洋上海的大小和相对组成，以了解对热带地区的大小和相对组成，以了解距离的机制，以确定其链接的平均循环和可变性，并确定互换的平均循环和可变性的机制，并确定互换的平均循环和变化。大西洋的循环随南半球的风力变化而变化。
