AO


AO: Arctic Oscillation. A swinging pendulum of sorts in the Arctic that determines how deep our supply of cold air is. A negative AO opens the spicket in terms of the cold air and a positive AO will shut the supply right off. This is one of the main teleconnections and forecasts for it can be found on the CPC site.
