What's wrong with this picture? https://earth.nullschool.net/#current/wind/isobaric/700hPa/orthographic=-90.46,73.25,446 edit........... it seems that way up in the stratosphere, we have a polar vortex.(centered on new siberian islands) with little effect on terrestrial weather. another edit.............. could this be effected by the early siberian snow cover this autumn?
Nice link! There is always a polar vortex, some years are stronger than others. https://en.m.wikipedia.org/wiki/Polar_vortex
We know that ssw events can disrupt the solar vortex, or split it into smaller vortices. What else can either disrupt, or stop a polar vortex from forming?
The sharp and dramatic greenhouse gas heating of the Arctic - an effect recently determined to have strongly influenced winter air and ocean temperatures, as well as summer - is the standard explanation for the modern weakening and occasional disruption of the polar vortex. The early Siberian snow would then likely be (as an initial presumption, since the mechanism is right there) another effect of those temperatures and that weakening.
This is what I was looking for: (ani't it beutiful?) https://earth.nullschool.net/#current/wind/isobaric/10hPa/orthographic=-88.71,83.74,446 Now if it just extends down into the troposphere a bit more-------singing and dancing..................
oops sorry 'bout the spelling down parka at the ready, firewood in the basement, ouzo and a nice whiskey warm the tummy.
