                     • A Benguela Niño developed from November 2010 to April 2011 along Angola and Namibia

                     • It was generated by a relaxation of the trade winds in the western equatorial Atlantic

                     • The equatorial origin was detected by altimetry and PIRATA mooring array

                     • The equatorial dynamical signature is reproduced by an ocean Linear Model forced by wind.

​                   •  Interannual Equatorial Kelvin waves in the tropical Atlantic are linked to major warm and cold events in the Angola Benguela Current system

                   •  Interannual Equatorial Kelvin waves at the origin of warm and cold events are well monitored by PIRATA moorings and altimetry

                   •  An interannual Equatorial Kelvin wave index is a skillful proxy to forecast warm and cold events by about 1 month
