Synergistic Effect of Warming in the Tropical Indian Ocean and North Tropical Atlantic on the Central-Pacific Type of La Nina Based on Observations and CMIP5
Previous studies have indicated that boreal winter-to-spring sea surface temperature anomalies (SSTA) over the tropical Atlantic or Indian Ocean can trigger the central-Pacific (CP) type of ENSO in the following winter due to winds over the western Pacific. Here, with the aid of observational data a...
