Arctic Oscillation
Graph Summary

Monthly values for the Arctic Oscillation Index, which tracks shifts in surface pressure between the mid-latitudes and the Arctic. During the positive phase, the jet stream stays farther north, and mid-latitude winters are milder than usual. Data from NOAA PSL.

Image Summary

Winter surface pressure patterns across the Northern Hemisphere when the Arctic Oscillation (AO) was negative (2009-10) and when it was positive (1988-89). The negative AO favors a warm Arctic and cool conditions across the eastern U.S. Data from NOAA CPC.

Teaser Summary

This index tracks coordinated shifts in air pressure and the jet stream between the Arctic and the mid-latitudes.

Graph of Arctic Oscillation values

Monthly values for the Arctic Oscillation Index, which tracks shifts in surface pressure between the mid-latitudes and the Arctic. During the positive phase, the jet stream stays farther north, and mid-latitude winters are milder than usual. During the negative phase, the jet stream dips into the mid-latitudes, creating cold-air outbreaks. NOAA Climate.gov image, based on data from NOAA CPC.

Two globes showing the pressure anomalies during each phase of the Arctic Oscillation

Winter surface pressure across the Northern Hemisphere compared to the 1981-2010 average when the Arctic Oscillation (AO) was strongly negative (top, 2009-10) and when it was strongly positive (bottom, 1988-89). The negative AO favors a warm Arctic and cool conditions across the U.S. and Europe. The positive phase favors a cool Arctic and relatively warm conditions in the mid-latitudes.
