Why the Arctic Dipole Anomaly Influences Mid-Latitude Weather Extremes
Quick fact
The Arctic Dipole Anomaly can push cold Arctic air down into the United States and Europe, causing severe winter storms, while at the same time bringing unusual warmth to other mid-latitude regions.
Why this is interesting
When the Arctic gets warmer, why do some places experience record-breaking cold and others suffer heatwaves? The answer lies in a specific pressure pattern called the Arctic Dipole Anomaly.
