At the same time, the additional snow cover has triggered a kind of feedback loop by changing what's called the Arctic Oscillation, the air pressure pattern that determines winter weather in the Northern Hemisphere.

Diminishing Arctic sea ice can cause changes in atmospheric circulation that lead to a circulation pattern that is different than the "negative phase" of the Arctic Oscillation.
They believe the increased snow cover has an intricate effect on the Arctic Oscillation -- an atmospheric pressure pattern in the mid- to high-latitudes -- causing it to remain in the "negative phase.
Arctic Oscillation--Impact On Storm Tracks While the Arctic Oscillation (AO) does not play a role in the number of named storms forecast, it is a factor in evaluating the probability of a land-falling storm.
What with all this climate change that's going on, maybe the southern oscillations have had a swap with the northern oscillations and invited the Arctic oscillation along for a laugh.
ENSO is one of the numbers of climate indices, each reflecting temperature or pressure changes at different locations on the earth's surface, and it has been demonstrated (9) that for the continental United States, seasonal (3-month) temperature and precipitation anomalies are related to climate index combinations, ENSO and Arctic Oscillation (AO), part of the larger Northern Annular Mode (NAM), rather than to a single index.
These patterns are related to natural climate variations, including El Nino and the Arctic Oscillation.
