| Summary: | – Surface and subsurface temperature has warmed up steadily since March 09, and the recent trends are favorable for a transition from ENSO-neutral to El Niño conditions during next 3 months. – Negative PDO phase since September 2007 has persisted for 21 months now, and 2008 has the lowest yearly mean PDO index since 1971. Indian Ocean – Since mid-March 09, zonal wind anomalies were persistently easterly and SST was persistently 0.5C above-normal. – The western tropical Indian Ocean SST went up to about 1C above-normal in May 09- the western pole of DMI was 1C above-normal. Atlantic Ocean – Tropical North Atlantic SST (TNA) continued a downward trend, and was slightly below-normal in May 09. Tropical South Atlantic SST (TSA) continued a upward trend, and was about 1C above-normal. – ITCZ was shifted southward in responding to the negative Meridional |
