Across the Northern Hemisphere, familiar seasons are starting to feel unfamiliar. Heat waves linger, cold snaps arrive out of sync, and storms stall over the same unlucky regions. At the heart of this ...

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 ...

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 ...

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 ...

The summer of 2025 brought unprecedented flash flooding across the U.S., with the central and eastern regions hit particularly hard. These storms claimed hundreds of lives across Texas, Kentucky and ...

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 ...

WASHINGTON — 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 ...

The summer of 2025 brought unprecedented flash flooding across the U.S., with the central and eastern regions hit particularly hard. These storms claimed hundreds of lives across Texas, Kentucky and ...

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 ...

(The Conversation) – The summer of 2025 brought unprecedented flash flooding across the U.S., with the central and eastern regions hit particularly hard. These storms claimed hundreds of lives across ...
