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

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 ...

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 ...

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

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

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 ...

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 ...

The biggest swings in the jet stream are associated with the most energy. Under the right conditions, that energy can bounce ...
