Highlights – August 2013
During August 2013, the sea surface temperatures (SSTs) remained near-average across the central and east-central
equatorial Pacific, and below average in the eastern equatorial Pacific (Fig. T18, Table
T2). The latest monthly
Niño indices were -0.3°C for the Niño 3.4 region
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) remained near-average
across the central and east-central equatorial Pacific (Figs. T15, T16).
during August, the equatorial low-level easterly trade winds remained near-average
across the equatorial Pacific (Table T1, Fig. T20), and tropical
convection remained enhanced over Indonesia and suppressed over the central
equatorial Pacific (Figs. T25, E3).
Collectively, these oceanic and atmospheric anomalies reflect a continuation of
