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 ...

A major snow and ice storm is expected to affect tens of millions of people from Texas to New England over the weekend. The storm is very large, and it could be particularly dangerous because a frigid ...

The long-chain effects of eruptive solar activities on Earth’s magnetosphere, ionosphere, and the mid-to-lower atmospheric circulation are an important theoretical research topic in the fields of ...

Accurately locating jet streams is key to understanding climate variability and regional weather patterns. However, the conventional Eulerian view of jets as fast winds overlooks their continuous ...

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 ...

In South America, southern Africa, Australia and Oceania, summer weather is heavily influenced by the Southern Hemisphere’s Eddy-Driven Jet (EDJ), a wind belt that flows between 1.3–1.5 kilometres ...
