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 ...

In the United States, our weather patterns usually travel from the west to the east. Sometimes, we can see variations in that a system will move in from the northwest or southwest, but Missourians ...

The polar night jet, the high-altitude winter wind that circles the Arctic, acts like a flywheel for the cold season in the Northern Hemisphere. As climate change erodes the temperature contrast that ...

The daily weather we experience is largely shaped by atmospheric conditions nearly 30,000 feet above us, where a key factor is the weather phenomenon known as the jet stream. Think of a jet stream as ...

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 ...
