What is it about?

The Southern Atlantic Subtropical Dipole is a phenomenon in which atmosphere and ocean varies in a coupled way, and it is important to South America and Western Africa climate. We demonstrated that when a dipole events takes place near October, the ocean holds this information and releases it in the winter of the next year.

Why is it important?

When something triggers a memory effect in a climate relevant parameter, like the sea surface temperature, there is a great potential to increase our ability to predict weather conditions within this memory effect.


The impacts of this memory effect on climate is still unknown. I'm studying this now, and hope that new interesting results will come.
