The Twenty second PIRATA conference (PIRATA 22 meeting) will occupy a prominent position, because the project celebrates its 20 years in 2017.
The Atlantic Ocean is subject to pronounced climate variations that occur on a wide range of time scales. Atlantic multi-decadal variability (AMV) associated with the Atlantic meridional overturning circulation has long been known to have global impacts. In particular, AMV has been linked to changes in the Indian, Asian and South American summer monsoons, and also to changes in the Pacific associated with the "global hiatus".
Tropical Atlantic climate recently experienced pronounced shifts of great socio-economic importance. The oceanic changes were largest in the eastern boundary upwelling systems. African countries bordering the Atlantic strongly depend upon their ocean - societal development, fisheries, and tourism. They were strongly affected by these climatic changes and will face important adaptation challenges associated with global warming. Furthermore, these upwelling regions are also of great climatic importance, playing a key role in regulating global climate.
