The purpose of this study is to evaluate the main aspects of the mesoscale ocean circulation of the Brazilian Equatorial Margin using a ten-year hydrodynamic hindcast that successfully represented in situ and satellite observational data. The seasonality and distribution of the Amazon River Plume (ARP), as well as the volume transport of the North Brazil Current (NBC) in two cross-current sections were described. The results indicate the NBC influences on the shape and spread of the ARP, and the relationship between the seasonal behavior of the Inter-tropical Convergence Zone migration, of the wind stress curl, and of the northern branch of the South Equatorial Current with the NBC pattern.

这项研究的目的是使用十年的水动力后预报来评估巴西赤道边缘中尺度海洋环流的主要方面，该预报成功地代表了原位和卫星观测数据。描述了亚马逊河羽流（ARP）的季节性和分布，以及两个交叉流段中的北巴西洋流（NBC）的体积运输。结果表明，NBC对ARP的形状和传播有影响，并且与NBC一起影响热带辐合带迁移，风应力卷曲和南赤道流北部分支的季节性行为之间的关系。模式。
