    Nice link! There is always a polar vortex, some years are stronger than others.

    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.
