A Regional Perspective: the Agulhas Current System

The Agulhas current is a Western Boundary Current that retroflects and joins the Atlantic Circumpolar Current (ACC). It has a very significant role in transferring heat into the Atlantic Ocean, as a branch of the Conveyor Belt return flow. It meets the cold Benguela Current off the Cape of Good Hope.

Infrared satellite observations are strongly affected by clouds. But the atmosphere is largely transfarent to MW microwaves. Differences are clear on the graphics above. The map on the left shows a 5-day composite (Jul 5th-9th, 2003) of sea surface temperatures over the South Atlantic Basin. There are areas where the cloud cover blocks the infrared radiation emitted by the underlying sea surface. This issue is mostly solved in MW imagery, as shows the figure on the right.
