| Summary: | – La Niña conditions (NINO3.4 <-0.5oC) weakened, and are expected to return to ENSO-neutral conditions in the Northern Hemisphere Spring. – Negative PDO phase that started in September 2007 has persisted for 18 months now, and 2008 has the lowest yearly mean PDO index since 1971. – Above-normal upwelling that has persisted since mid-November 2007 switched to below-normal in later February along the western coast of North America south of 35N. • Indian Ocean – Positive SST anomalies presented in the western Indian Ocean. – IOD index became weakly positive. • Atlantic Ocean – Above-normal SST in North Atlantic persisted. – Above-normal SST in the tropical North Atlantic returned to near-normal or below-normal, while above-normal SST in the tropical South Atlantic and equatorial Atlantic persisted. |
