Summary of atmospheric transport from the Tropical Pacific Ocean.
Solid arrows show an increase in mass transport during El Niño; dashed arrows a decrease. Blue arrows show the transport of relatively moist air to anomalously moist local conditions (marked with blue shading), while brown arrows show transport of dry air to anomalously dry local conditions (brown shading). Red circles show transport of warm air aloft that favors stable conditions. Orange shading shows transport of anomalously greater amount of heat from the Pacific Ocean to the Tropical Atlantic.
