Highlights – March 2014
During March 2014, sea surface temperatures (SSTs) were below-average across the eastern equatorial Pacific and
above-average over the central equatorial Pacific (Fig.
T18, Table T2). The latest monthly Niño indices were -0.2°C for
the Niño 3.4 region and -0.8°C for the Niño 1+2 region (Table T2,
However, a downwelling
oceanic Kelvin wave has produced a significant sub-surface warming across the
central and eastern equatorial Pacific during March and consistent with these
depth of the oceanic thermocline (measured by the depth of the 20°C
isotherm) were above-average across the eastern equatorial Pacific (Figs. T15, T16).
during March, the low-level easterly trade winds remained below-average across
the equatorial Pacific (Table T1, Fig. T20). Meanwhile,
tropical convection remained enhanced over the central equatorial Pacific and suppressed
across Indonesia and western equatorial Pacific (Figs. T25, E3). Collectively, these oceanic and
atmospheric anomalies reflect a continuation of ENSO-neutral conditions.
