This is a NOAA website which summarizes the behavior of the Arctic Oscillation.

The Arctic Oscillation is a characteristic of the atmosphere, most important in winter and spring, but present all year.  An index measures positive and negative states.   The Arctic Oscillation is defined by  the difference in pressure patterns, and describes the pattern of high and low pressure systems.  It is important to the Great Lakes because it greatly influences persistent warm and cool spans of tempertures.
