4.Sea Surface and Atmospheric State
PACIFIC SEA STATE ( Text Courtesy IRI - January 21, 2020)
SSTs in the east-central Pacific were near the borderline of weak El Niño levels during mid-January. Patterns in atmospheric variables have mainly maintained neutral conditions, with some trends toward El Niño. Most model forecasts favor borderline weak El Niño SST conditions during winter, returning to ENSO-neutral by early spring and beyond. The official CPC/IRI outlook is consistent with these model forecasts.
