Tropical
Highlights - June 2016
Sea surface
temperatures (SSTs) were near-average
across the central and eastern equatorial Pacific during June 2016 (Fig. T18, Table T2). The latest monthly Niņo indices were -0.1°C for
the Niņo 3 region, -0.1°C for the Niņo 3.4 region, and +0.3°C for the Niņo 1+2 region (Table
T2, Fig. T5). The depth of the oceanic thermocline
(measured by the depth of the 20°C isotherm) remained below-average across the
central and eastern equatorial Pacific (Figs. T15,
T16), and
the corresponding sub-surface temperatures were 1-3°C below average (Fig. T17).
Also during June, the upper and
lower-level winds were both near-average across the central and eastern equatorial
Pacific (Table T1,
Figs. T20, T21).
Meanwhile, convection was near-average over most of the equatorial Pacific (Figs. T25, E3). Collectively, these oceanic and
atmospheric anomalies reflect a transition from El Niņo to ENSO-neutral
conditions.
