Each hemisphere hosts two primary jet streams: The polar jet stream is typically found near 50 to 60 degrees latitude, across Canada in the Northern Hemisphere, where cold polar air meets warmer ...

A multi-century climate record suggests that current Atlantic jet-stream variations are not the cause of an increase in extreme weather events. Read the paper: Past hydroclimate extremes in Europe ...

The jet stream, or any wind, is the result of differences in surface temperature. In simple terms, warm air rises, creating low pressure, and cold air sinks, creating high pressure. Wind is the ...

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 ...

At the same time, every hurricane that formed, including the three powerful Category 5 storms, steered clear of the U.S. mainland. Both scenarios were unusual – and they were largely directed by the ...
