The pattern of tropical sea surface temperature (SST) anomalies

Tropical Highlights - October 2014



During October 2014, sea surface temperatures (SSTs) were above-average across the equatorial Pacific (Fig. T18, Table T2). The latest monthly Niņo indices were +0.5C for the Niņo 3.4 region and +0.8C for the Niņo 1+2 region (Table T2, Fig. T5). The depth of the oceanic thermocline (measured by the depth of the 20C isotherm) was near-average over much of the equatorial Pacific (Figs. T15, T16).

Also during October, the low-level easterly trade winds remained near-average across the equatorial Pacific (Table T1, Fig. T20). Meanwhile, suppressed tropical convection was observed over Indonesia (Figs. T25, E3). Collectively, these oceanic and atmospheric anomalies reflect a continuation of ENSO-neutral conditions.
