9529813 MacCready In this project, the PI will study the circulation ACROSS the Antarctic Circumpolar Current, estimated to be about 1/3 as large as the circulation OF the ACC. It is hypothesized to be due to wind forcing. This study will investigate the sensitivity of the meridional circulation, both in strength and depth distribution, to aspects of the forcing, specificially to differences in wind stress, buoyancy flux, bottom topography, and source-water availability, using an existing, eddy-resolving, shallow-water equation numerical model, formulated as a series of isopycnal layers.

在这个项目中，PI将研究横跨南极环极流的环流，估计大约是ACC环流的1/3。据推测，这是由于风的强迫。本研究将研究经向环流在强度和深度分布方面对强迫的敏感性，特别是对风应力、浮力通量、底部地形和水源可利用性的差异，使用现有的涡流解析浅水方程数值模型，将其制定为一系列等压线层。
