4.Sea Surface and Atmospheric State 


PACIFIC SEA STATE ( Text Courtesy IRI - February 18, 2020)

SSTs in the east-central Pacific were neutral, but above average during mid-February. Patterns in atmospheric variables are split between neutral and weak El Niño conditions. Most model forecasts favor warm-neutral SST conditions during spring, cooling to average by early summer. The official CPC/IRI outlook is consistent with these model forecasts, calling for continuation of ENSO-neutral.
