The Role of Agulhas Rings in the Western South Atlantic

主要研究者：NofProposal：9911324提供资金用于分析和数值模拟Agulhas涡旋对巴西-马尔维纳斯汇流区的影响。 特别是，环吸收对巴西电流强度的时间变化的影响将建模。 这股海流的强度变化影响到巴西-马尔维纳斯汇流区的迁移。不同的假设有关的形成和剥离的入侵涡旋也将进行测试。建模研究将开始于一个简单的简化重力、一个半层分析模型和一个半数值等密度线，然后转向更现实的两层模型。

PI: NofProposal: 9911324Funds are provided for both analytical and numerical modeling of the influence of Agulhas eddies on the Brazil-Malvinas Confluence Zone. In particular, the influence of ring absorption on the temporal variability of the Brazil Current strength will be modeled. Variability of the strength of this current influences the migration of the Brazil-Malvinas Confluence Zone. Different hypotheses concerning the formation and detachment of intrusion eddies will also be tested. The modeling studies will begin with a simple reduced gravity, one and a half layer analytical model and a one and a half numerical isopycnic before moving on to more realistic two layer models.
