Highlights - June 2017
temperatures (SSTs) during June 2017 remained near-average in the eastern equatorial Pacific and
above-average across the central and east-central equatorial Pacific (Fig. T18, Table T2). The latest monthly Niņo indices were +0.6°C for
the Niņo 4 region, +0.6°C for the Niņo 3.4 region, and +0.1°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) was near-average over the central
and eastern equatorial Pacific (Figs. T15, T16), and
the corresponding sub-surface temperatures were 0-1°C above average (Fig. T17).
Also during June, the lower-level
and upper-level winds were near average across most of the equatorial Pacific (Table T1, Figs. T20, T21). Meanwhile, convection
was suppressed over the central equatorial Pacific and enhanced over western
equatorial Pacific (Figs. T25, E3).
Collectively, these oceanic and atmospheric anomalies are consistent with ENSO-neutral
