Description
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 19 months now. – Coastal upwelling is strongly above-normal between 36N-42N, and below-normal in the other regions. • Indian Ocean – Positive SST anomalies persisted in the western Indian Ocean. – Positive IOD index enhanced and became above 0.5 oC in March 09. • Atlantic Ocean – Positive SSTA in the North Atlantic SST weakened in Feb-Mar 09. – Tropical North Atlantic SST became slightly below-normal in Feb-Mar 09. – Tropical South Atlantic and equatorial Atlantic continued to be above-normal.
