Highlights – May 2014
During May 2014, sea surface temperatures (SSTs) were above-average across much of the eastern and central
equatorial Pacific (Fig. T18, Table T2). The latest monthly Niño indices were +0.5°C for
the Niño 3.4 region and +1.3°C for the Niño 1+2 region (Table
T2, Fig. T5). Consistent with these conditions, the depth
of the oceanic thermocline (measured by the depth of the 20°C isotherm) was
above-average across the central and eastern equatorial Pacific (Figs. T15, T16), with corresponding
sub-surface temperatures being 2-5°C above average (Fig. T17).
during May, 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 near average over much of the equatorial
Pacific (Figs. T25,
E3). Collectively, these oceanic
and atmospheric anomalies reflect a continuation of ENSO-neutral conditions.
