Matano9819223This work will examine the coupling between the general circulationof the Indian and South Atlantic Oceans that occurs via the Agulhas Current system. Combining diagnosis of existing model output, stability analysis of typical Agulhas Current profiles, process modeling and an analysis of regional variability in satellite-derived SSH and SST fields, the work will focus on: (a) an investigation of whether westward propagating disturbances in the tropical Indian Ocean influence the variability of the Agulhas Current retroflection, together with the mechanisms that connect the two, and (b) a study of the influence of variability in the South Atlantic subtropical gyre and in the Agulhas Current on the composition and variability of the Benguela Current system.

马塔诺9819223这项工作将研究通过阿古拉斯洋流系统发生的印度洋和南大西洋一般环流之间的耦合。这项工作将结合现有模式输出的诊断、典型阿古拉海流廓线的稳定性分析、过程模拟和卫星衍生的SSH和SST场的区域变率分析，重点放在：(A)研究热带印度洋向西传播的扰动是否影响阿古拉海流反射的变率，以及将两者联系在一起的机制；(B)研究南大西洋副热带涡旋和阿古拉海流的变率对本格拉海流系统的组成和变率的影响。
