大阿古拉斯海流系统的时间变率具有重要的气候学影响。最近的一些结果表明，这种变率包含很大的季节成分，这是由于仅马达加斯加向极地纬度的环流变化造成的。一个模式模拟表明，热带地表水通过莫桑比克海峡对阿古拉斯洋流的贡献也具有明显的季节性特征，这是由热带印度洋上的季节性风应力带来的。这种通过英吉利海峡的模拟水流对阿古拉斯海流的季节性有很大贡献。这一模式结果与现有的水文观测结果并不矛盾。
The temporal variability of the greater Agulhas Current system has important climatological consequences. Some recent results have suggested that this variability contains a large seasonal component, due to changes in the circulation at latitudes poleward of Madagascar only. A model simulation shows that the contribution of Tropical Surface Water to Agulhas Current waters, via the Mozambique Channel, also has a distinct seasonal characteristic that is brought about by the seasonal wind stress over the tropical Indian Ocean. This simulated flow through the Channel contributes substantially to the seasonality of the Agulhas Current. This model result is shown to be not inconsistent with available hydrographic observations.
