Extended Data Fig. 3: Precipitation and surface wind anomalies of each observed extreme/moderate northward swing event.
From: Increased extreme swings of Atlantic intertropical convergence zone in a warming climate
MAM-averaged precipitation (mm day-1, color shading) and surface wind (m s-1, vectors) anomalies for observed extreme and moderate events in a 1983, b 1990, c 1992, d 1993, e 1998, f 2010, and g 2012. Specially, the 1983 extreme event caused extreme droughts across the equatorial Atlantic basin, extending from central-eastern Amazon to the west coast of Africa, together with strong cross-equatorial winds. Other moderate events caused relatively small droughts in scale and intensity, but severe droughts in the north-east Brazil.
