The jet stream, a warming Arctic, and loads of atmospheric moisture have contributed to an epic storm impacting 230 million ...

A blast of winter cold doesn’t contradict climate change — it often reflects how a warming planet is making weather more ...

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 ...

Climate change does not just mean warmer weather everywhere. This video explains how rapid Arctic warming can weaken the polar vortex, distort the jet stream, and allow frigid air to plunge south into ...

A severe winter storm that brought freezing rain, sleet and snow to a large part of the U.S. was intensified by the polar ...

Tens of millions of people are in the path of a major winter storm. Federal cuts threaten efforts to understand the causes of ...

A warmer atmosphere has the potential to hold more moisture, which can contribute to heavier precipitation in any season, scientists say.

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 ...

Climate deniers are quick to say ‘I told you so’ when the mercury drops. But a warmer planet impacts weather in ways that can seem counterintuitive. Record cold temperatures are once again expected to ...
