Winter 2023-24 is approaching, and a new Polar Vortex is strengthening in the Stratosphere over the North Pole.

In recent years, the phrase ‘Polar Vortex’ has been adopted by the climate cabal to mean descending Arctic air masses. In this article it will reflect the strength of the stratospheric polar circulation which, whether it be weak or strong, plays a crucial part in our Winter weather.

Human-caused global heating is directly responsible for the recent extreme heat events
As we head into autumn, the Sun gets lower and the polar regions begin to cool as there is less energy to fuel them.

However, as polar temperatures drop, the atmosphere further south remains relatively warm. This causes a strong temperature difference between the polar and sub-tropical regions, and a large low-pressure (cyclonic) circulation starts to develop across the Northern Hemisphere, extending from the surface layers to high up into the atmosphere — the ‘Polar Vortex’.

Climate alarmists claim that a warming Arctic is leading to an increase in violent storms. However, if the Arctic is indeed warming “twice as fast as the rest of the planet”, as is also claimed, then the temperature difference between it and the lower latitudes will actually decrease which, The Science informs, will lead to less favorable conditions for low pressure systems to develop.

Key to note, the Polar Vortex is not just one winter storm or a single cold outbreak. Rather, it is a large cyclonic area spinning above the entire Northern Hemisphere, from the ground to the top of the Stratosphere–and beyond to over 50 km (31 miles).
 


Polar Vortex at around 30 km (18.5 miles) during Winter. Temperatures drop quickly as you approach its cold inner core.

The strength of this stratospheric polar circulation (Polar Vortex) can mean the difference between a very cold and snowy winter and a warm and dry winter.

Though not an exact science, a strong Polar Vortex will see cold air locked in the Polar regions, meaning milder conditions for the mid-latitudes. Conversely, weak Polar Vortex will lead to a looser polar jet stream flow, and the Arctic will have a harder time containing its cold air which is now free to escape south and crash into the likes of North America and/or Europe:

By a logical extension, solar activity can also contribute to the stability of the jet streams.

Since around 2008, solar output has been holding at historically low levels. Combined, the past two solar cycles (24 and the ongoing 25) are on course to be the weakest pair of cycles since those of the Dalton Minimum (1795 – 1815).

This low output is appears to be changing our weather by weakening the jet streams, which has the effect (in the NH) of either pulling up Tropical warmth to unusually-high latitudes, or dragging down Polar cold unusually-far south.
