Large-scale Forcing of the Agulhas Variability

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环流之间的耦合。结合对现有模式输出的诊断、典型阿古拉斯洋流剖面的稳定性分析、过程建模以及卫星衍生的海平面和海温场的区域变率分析，工作将侧重于：(a)调查热带印度洋向西传播的扰动是否影响阿古拉斯海流反射的变率，以及将两者联系起来的机制；(b)研究南大西洋亚热带环流和阿古拉斯海流的变率对本格拉海流系统的组成和变率的影响。

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.
