The Dartmouth study found that pronounced waviness in the jet stream from the 1960s-1980s led to the warming hole, a 30-year period of abnormally cool temperatures centered on the Southeast. The researchers report that waviness caused the warming hole to park over the South in winter, creating a glide path for Arctic air to routinely flow into the region.
