Tropical
Highlights - October 2014
During October
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
and +0.8C
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 near-average over much of the equatorial
Pacific (Figs. T15, T16).
Also
during October, the low-level easterly trade winds remained near-average across
the equatorial Pacific (Table T1, Fig. T20). Meanwhile,
suppressed tropical convection was observed over Indonesia (Figs. T25, E3). Collectively, these oceanic and
atmospheric anomalies reflect a continuation of ENSO-neutral conditions.
