• The 2013 SST anomaly (SSTA) was characterized by positive SSTA in the central North Pacific, Indo-Pacific warm pool (IPWP), North Atlantic and negative SSTA in the eastern equatorial Pacific (EPAC). • The positive SSTA over IPWP exceeding +1 STD persisted throughout 2013. Negative SSTA exceeding-1 STD emerged in EPAC during summer and persisted into fall 2013. Based upon the NINO3.4 index, the tropical Pacific was in ENSO-neutral conditions in 2013. • The North Pacific SSTA was characterized by a negative phase of PDO which has persisted from May 2010 to present (3.7 years). • The positive SSTA over IPWP has persisted since 2000 favoring persistent La Nina-like atmospheric circulations.
