Collaborative Research: A Study of the Role of Eddies in Agulhas Leakage and the Circulation in the Southeastern Atlantic using KAPEX Float Data

0236527/0236654理查森/伍德该项目包括对作为非洲南端KAPEX实验的一部分部署的RAFOS漂浮物的轨迹进行分析，并结合来自海面漂流者和卫星高度计的辅助数据。对这些轨迹的初步分析表明，它们中的许多都被困在了阿古利斯旋涡中。这项工作的一个动机是相信，阿古尔哈斯旋涡既提供了从印度洋流入大西洋的重要管道，也搅动了东南大西洋的海洋。拟议的分析试图总结生活史和统计数据(包括：数量、大小、漩涡速度、平移速度以及涡旋之间的相互作用和与水深测量的相互作用)。研究人员将把轨迹的细节与该地区各种数值模型的输出进行比较，并与一名德国研究人员合作绘制南大西洋的中深度速度场图。

0236527/ 0236654 Richardson/WoodingThis project consists of an analysis of the trajectories of RAFOS floats, deployed as part of the KAPEX experiment around the southern tip of Africa, in combination with ancillary data from surface drifters and satellite-borne altimeters. Preliminary analysis of these trajectories show that many of them were trapped in Agulhas eddies. A motivation for this work is the belief that Agulhas eddies both provide a significant conduit for flow from the Indian Ocean into the Atlantic and stir the ocean in the south-eastern Atlantic. The proposed analysis seeks to summarize the life history and statistics (including: number, size, swirl velocity, translational velocity, and the interactions of eddies with each other and with bathymetry). The investigator will compare the details of the trajectories with output from various numerical models of the region and collaborate with a German investigator in mapping the intermediate-depth velocity field in the S. Atlantic.
