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.
