Highlights - June 2015
June 2015, sea surface temperatures (SSTs) remained above-average across the equatorial Pacific (Fig. T18, Table
T2). The latest monthly
Niņo indices were +1.1°C for the Niņo 4
for the Niņo 3.4 region, and +2.5°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) also remained above-average across
the eastern equatorial Pacific (Figs. T15, T16), and the corresponding sub-surface
temperatures were 1-6°C above average (Fig.
during June, the low-level westerly wind anomalies and upper-level easterly
wind anomalies continued across the western and central equatorial Pacific (Table T1, Figs. T20, T21). Meanwhile,
enhanced convection persisted across the central and eastern equatorial Pacific
and suppressed convection was observed over Indonesia (Figs. T25, E3). Collectively, these oceanic and
atmospheric anomalies are consistent with El Niņo conditions.
