Tropical
Highlights - June 2024
During June
2024, sea surface
temperatures (SSTs) remained near average across the east-central
and eastern equatorial Pacific (Fig. T18). The latest monthly Nino indices were -0.7C for
the Nino 1+2 region, +0.2C for the Nino 3.4 region and +0.7C for the Nino 4 region (Table T2). The depth of the oceanic thermocline
(measured by the depth of the 20C isotherm) was below-average across the equatorial
Pacific (Figs. T15, T16).
The corresponding sub-surface
temperatures were 1-6C below-average in the far eastern equatorial Pacific (Fig. T17).
Also during June, lower-level wind anomalies
were easterly over the western equatorial Pacific, while upper-level wind
anomalies were near average across the equatorial Pacific (Table T1, Figs. T20, T21).
Meanwhile, tropical convection was slightly suppressed around the Date Line and
was near average around Indonesia (Fig. T25). Collectively, these oceanic and atmospheric
anomalies were consistent with ENSO-neutral conditions.
