What Does AO Stand For?
AO stands for Arctic Oscillation
The Arctic Oscillation (AO) is a climate phenomenon characterized by fluctuations in atmospheric pressure patterns over the Arctic region. It influences weather conditions in the Northern Hemisphere by affecting circulation patterns in the polar vortex, which can lead to variations in temperature and precipitation. The AO is often measured using an index that reflects the strength and phase of these pressure patterns, thus playing a significant role in seasonal weather forecasting and understanding climate dynamics.
