Highlights – March 2013
During March 2013, the sea surface temperatures (SSTs) remained near-average across the equatorial Pacific (Fig. T18, Table T2). The latest monthly Niño indices were -0.2°C for
the Niño 3.4 region and +0.1°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) remained near-average across the central and east-central equatorial
Pacific (Figs. T15, T16).
during March, the equatorial low-level easterly trade winds remained near-average
across the equatorial Pacific (Table T1, Fig. T20) and enhanced
convection was seen over the western equatorial Pacific (Figs. T25, E3). Collectively, these oceanic and
atmospheric anomalies reflect a continuation of ENSO-neutral conditions.
