Storms tend to form at the boundaries between cold and warm air.
The unique geography of the Arctic leads to unique weather patterns that reappear in the region year after year.
But maps of sea level pressure can also be averaged over several months or years, to show the average circulation patterns in the atmosphere. your guide for all types of crafts holiday crafts, kids crafts, crochet, knitting, dolls, rubber stampsIt is worth remembering that although the printed polar patterns are in two dimensions as below, the actual pattern is three-dimensional for example, an© 2020 - Free Patterns | Polar lows range in size from around 100 to 500 kilometers (62 to 310 miles) in diameter.

The Arctic Oscillation is an atmospheric circulation pattern that occurs over the mid-to-high latitudes of the Northern Hemisphere, including the Arctic. The storms can develop rapidly, reaching their maximum strength within 12 to 24 hours of formation, but they dissipate just as quickly, lasting on average only one or two days.Weather maps show the circulation and pressure patterns over one or several days.

For a period during the 1970s to mid-1990s, the Arctic Oscillation tended to stay in its positive phase.

These averaged maps remove some of the variability caused by day-to-day weather changes, instead showing longer-term patterns that can affect weather and climate both within and outside of the Arctic.Researchers compare the relative strengths of semipermanent highs and lows, and report these comparisons in indices such as the North Atlantic oscillation and the Arctic oscillation.
