Highlights - September 2014
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
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 above-average over much of the equatorial
Pacific (Figs. T15, T16), with corresponding
sub-surface temperatures being 1-3C above average in the eastern equatorial
Pacific (Fig. T17).
during September, the low-level easterly trade winds remained near-average across
the equatorial Pacific (Table T1, Fig. T20). Meanwhile,
enhanced tropical convection was observed over the western equatorial Pacific (Figs. T25, E3). Collectively, these oceanic and
atmospheric anomalies reflect a continuation of ENSO-neutral conditions.
