Tropical
Highlights - June 2022
During June
2022, sea surface
temperatures (SSTs) remained below-average across the central
and eastern equatorial Pacific (Fig. T18). The latest monthly Niņo indices based on
OISSTV2.1 were -1.4C for the Niņo 1+2 region, -0.7C for
the Niņo 3.4 region and -0.6C for the Niņo 4 region (Table T2). The depth of the oceanic thermocline
(measured by the depth of the 20C isotherm) was above-average across much of equatorial
Pacific and below-average in the far eastern equatorial Pacific (Figs. T15, T16).
Also during June, the lower-level easterly
winds and the upper-level westerly winds were above-average across the western
and central equatorial Pacific (Table T1, Fig. T20, Fig. T21). Meanwhile,
tropical convection was suppressed over much of the central and western equatorial
Pacific and enhanced over Indonesia (Fig.
T25). Collectively, these oceanic and
atmospheric anomalies were consistent with La Niņa conditions.
