In the Northern Hemisphere
Sudden Stratospheric Warmings
( SSW’s )
happen more often,
and in the month
after, wild polar blasts
can happen.
The warming up high in the
stratosphere can change the
normal jet streams,
and then weeks later,
down at the surface,
cold air from the poles
can end up may wandering
far south.
In the Southern Hemisphere,
there have only been two
officially recorded SSW’s
in the last 50 years, one in
2002 and a minor one in 2010.
A very rare southern SSW
is taking place, over Antarctica.
Some researchers are using
the word “historic”.
SSWs are rare over the Southern
Hemisphere due to Antarctica's
shape, and being surrounded
by water.
Climate modelers are still trying
to define SSW’s, perhaps as
a wind reversal, or a temperature
gradient change? (Junsu Kim 2017).
The best meteorologists can
predict a SSW up to week in advance.
Could Africa, Australia, Argentina,
or New Zealand get unusual snow,
or severe frosts?
Scientists did not predict this.
And they have no idea
what will happen.
But many claim
to be "sure" about
the global climate
100 years from now !
Here's my prediction
( and this is what
I always predict ! ):
-- If there is unusually cold weather,
it will be ignored, or described
by the media as "local weather".
-- If there is unusually warm weather,
it will be in media headlines,
described as "climate change",
and claimed to be proof of a
coming climate catastrophe !
