Our current jet stream configuration is so straight you could trace it with a ruler. I'm sure you've heard of the jet stream, the narrow bands of stronger winds that circulate high above the ground.

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 ...

The jet stream also played a role in the 2025 hurricane season. Given its west-to-east wind direction, the southward dip of the jet stream—along with a weak high pressure system over the ...
