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 ...

Learn how climate change is causing warmer winters, intense storms, and unpredictable weather patterns. Scientists warn of ...

Last month’s prolonged Arctic outbreak caused the coldest December in 15 years. Winter-weary Berkshire residents are ...

Using historical winter temperature records from weather stations across Ireland between 1950 and 2022, we found a large reduction in extreme cold. The coldest winter days are becoming both less ...

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 ...

First, instead of moving storms quickly eastward, the sluggish jet stream stalled storm systems in place, causing prolonged ...

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 scientists have long watched the jet stream with fascination and growing concern. These rivers of air racing across our planet at altitudes of roughly 5-9 miles dictate much of our day-to-day ...

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 ...

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 ...
