transition from La Niņa to ENSO-neutral conditions occurred during June 2008,
as sea surface temperatures (SSTs) returned to near-average across the
Also, positive SST anomalies continued in the eastern equatorial Pacific.
Consistent with this pattern, the latest monthly SST index was -0.3°C in the Niņo-3.4
region, and +0.6°C in the Niņo 1+2 region (Table
T2). Across the equatorial Pacific, a deeper than
average thermocline (Fig. T16) and above
average temperatures (+1°C to
thermocline depth also
reflected the transition to ENSO neutral conditions (Fig. T17).
low-level easterly winds and upper-level westerly winds continued across the
central equatorial Pacific during June (Figs.
T20, T21, Table T1).
Convection remained suppressed throughout the central equatorial Pacific and
enhanced over the far western Pacific (Figs.
Collectively, these atmospheric conditions continued to indicate a lingering La
