Climate scientists have long watched the jet stream with fascination and growing concern. These rivers of air racing across our planet at altitudes of roughly 5-9 miles dictate much of our day-to-day ...

A new study challenges the idea that climate change is behind the erratic wintertime behavior of the polar jet stream, the massive current of Arctic air that regulates weather for much of the Northern ...

In South America, southern Africa, Australia and Oceania, summer weather is heavily influenced by the Southern Hemisphere’s Eddy-Driven Jet (EDJ), a wind belt that flows between 1.3–1.5 kilometres ...

First, instead of moving storms quickly eastward, the sluggish jet stream stalled storm systems in place, causing prolonged ...

Dartmouth researchers used machine learning and long-term climate records to construct a timeline of jet-stream variability since 1901. Nearly all prior studies of the jet stream focus on the period ...
