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 ...

Jet streams are often referred to as the "motor" of global weather: High-altitude wind currents steer areas of high and low pressure, playing a crucial role in shaping our weather. However, how these ...

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 ...

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 ...

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 ...
