For
the last 3 months, the global average lower tropospheric temperature anomaly
was hovering around the +0.30 deg C range. For September, 2011 it
retreated a little again, to +0.29 deg. C (click on the image for the full-size
version). The monthly statistics suggests the Tropics are where the positive anomaly
is found the least.
Global sea surface temperature AMSR-E data
for October 3 suggests it’s on its lowest from which satellite measurement
commenced in 2003. Meanwhile all atmospheric indicators are touching on La Niña
thresholds, with NINO3.4 at -7 and the 30-day Southern Oscillation Index (SOI)
at +11.4.
Cloudiness near the Date Line remains
suppressed since April 2010 when the La Niña first appeared indicating that
there is no respite indicating that the drought in Texas and East Africa shows
no hope of receding.
[Cloudiness along
the equator, near the Date Line, is an important indicator of ENSO conditions,
as it typically increases (negative OLR anomalies) near and to the east of the
Date Line during an El Niño event and decreases (positive OLR anomalies) during
a La Niña event.]
Historically, global temperature lag the La
Niñas/El Niños by 3 to 6 months and accordingly it is likely that we see a more
dramatic drop this month (October) as the effects of the La Niña start kicking
in.
There are indications that the winter jet
pattern too may settle in early. Switzerland for example has already received
snow early last month. Winter may prove "catastrophic"
(apologies for borrowing the favourite term of climate alarmists) in a
number of geographies.
But the caveat is that NOAA’s Space weather
prediction center released their solar cycle progression updates, and it shows
one of the largest jumps for all common solar metrics since cycle 24 began. The
sunspot number jumped significantly due to the recent large sunspot group
that released X-class flares.
Whether the sunspot number will decline or
increases in the months ahead can depend how cold or warm winter will be.
