The pattern of tropical sea surface temperature (SST) anomalies

Tropical Highlights – June 2014



 During June 2014, sea surface temperatures (SSTs) were above-average across the equatorial Pacific (Fig. T18, Table T2). The latest monthly Niño indices were +0.5°C for the Niño 3.4 region and +1.8°C for the Niño 1+2 region (Table T2, Fig. T5). The depth of the oceanic thermocline (measured by the depth of the 20°C isotherm) was above-average mainly over the eastern equatorial Pacific (Figs. T15, T16), with corresponding sub-surface temperatures being 1-4°C above average (Fig. T17).

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