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 ...

Previous studies using an emergent constraint have suggested that climate models underestimate the winter jet stream response to sea ice loss, casting doubt on the quality of mid-latitude climate ...

WASHINGTON (AP) — Nearly every type of wild weather hit some part of the United States on Monday as the normal changing seasons clash of cold and warm air collided with a jet stream gone crazy and a ...

Something has shifted in the way climate scientists talk about their own work. The language has become noticeably more ...

Nobody enjoys turbulence. Flight crews would prefer to avoid it, and passengers find it unnerving. Even seasoned travelers can become uneasy when a disturbance is particularly intense or 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 ...
