Black arrows represent low-level atmospheric circulations. Red shadings indicate sea surface warming, while blue shadings indicate atmospheric cooling or suppressed convection. Acronyms include: eastern Pacific (EP), North Indian Ocean (NIO), anomalous cyclonic circulation (ACC), and western North Pacific anomalous anticyclonic circulation (WNPAC).
