Let's discuss differences in barometric pressure at polar latitudes, during different stages of the solar cycle.

"The magnitude of the change in the troposphere is large enough to
alter sea level pressure fields such that a more positive
winter Southern Annual Mode (lower pressure at higher
latitudes) is produced in about 70% of the cases (especially
with climatological and historical SST). The sea level
pressure differences are on the order of 4 mb at high
southern latitudes"

"This effect, as well as the winter zonal
wind change descending into the troposphere, is more
consistent in the Southern Hemisphere during June –August
then in the Northern Hemisphere for December–February,
most likely owing to the greater planetary wave forcing and
inherent variability during Northern Hemisphere winter"
