of global tropical sea surface temperature (SST) during November featured
near-average SSTs everywhere, except negative anomalies in the eastern
tropical Pacific (Fig. T18, Table T2).
The overall patterns of convection,
SSTs, low-level winds and upper-level winds remained near average over the
central and eastern tropical Pacific during November 2005 (Figs. T18,
T20, T21 and T25),
which is consistent with ENSO-neutral conditions.
thermocline, measured by the depth of the 20°C
isotherm along the equator, featured near-average depth in the central
Pacific and slightly shallower-than-average depth in the eastern Pacific
during November (Figs. T15, T16).
Consistent with these conditions, equatorial oceanic temperatures at
thermocline depth were near average throughout most of the Pacific and 1-3oC
below average in the eastern Pacific (Fig. T17).
November, near-average low-level winds were observed over the eastern
equatorial Pacific while low-level easterly anomalies (more than 3.0 m s-1)
were observed over the central and western equatorial Pacific (Fig. T20).
In the global tropics, enhanced convection (above-average rainfall amounts)
was observed over
, as well as over the
North Atlantic/Central America
T26 and E3),
the latter was consistent with the very active Atlantic hurricane season.
- Darwin SOI for November is -0.3 (Table T1,
Fig. T1), while the equatorial SOI for November
is +1.3 (Fig. T2). The equatorial SOI has
been greater than or equal to +0.5 for the last three months.
