Tropical
Highlights - November 2014
During November
2014, sea surface temperatures (SSTs) were above-average across the equatorial Pacific (Fig. T18, Table
T2). The latest monthly
Nino indices were +0.9C for the Nino 3.4 region
and +0.7C
for the Nino 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 the east-central and
eastern equatorial Pacific (Figs. T15, T16), and the corresponding sub-surface
temperatures were 1-3C above average in those regions (Fig. T17).
Also
during November, the low-level easterly trade winds remained near-average across
much of the equatorial Pacific (Table T1, Fig. T20). Meanwhile,
suppressed tropical convection was observed over Indonesia and near the Date
Line (Figs. T25,
E3). Collectively, these oceanic
and atmospheric anomalies reflect a continuation of ENSO-neutral conditions.
