As the Arctic rapidly warms, the temperature difference between the polar region and lower latitudes decreases, which weakens the jet stream.

The science behind the storm is an active area of study. Most of the US is bracing for a prolonged stretch of frigid weather and a massive winter storm that could wreak havoc on roads and power grids over the next several days.

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 since 1979, when data on weather and climate systems ...

First, instead of moving storms quickly eastward, the sluggish jet stream stalled storm systems in place, causing prolonged downpours and flash flooding. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

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.

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 above the ground. Current climate models have ...

The seatbelt sign pings on, trays rattle, drinks slosh in their glasses. For many flyers, air turbulence can be an unnerving experience -- and in a world warming under the effects of climate change, it is only set to worsen, according to a growing body ...
