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 ...

Scientists say a closely watched atmospheric pattern — the jet stream — is behind both the Canadian wildfires and the scorching heat in Texas, raising questions about how it shapes extreme weather ...
