Summer 2024 was officially the Northern Hemisphere’s hottest on record. In the United States, fierce heat waves seemed to hit somewhere almost every day. Overall, the global average temperature was ...

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

A multi-century climate record suggests that current Atlantic jet-stream variations are not the cause of an increase in extreme weather events. Read the paper: Past hydroclimate extremes in Europe ...

At the end of October 2024, a grey gloom descended over the British Isles. Nothing unusual there. But this murky shroud was particularly persistent, even for the UK. Some regions barely saw the sun ...

Picture this: you're checking tomorrow's weather for the tenth time this week, and each time the forecast has shifted. What ...

Tree-ring data reveal that periodic shifts in strong winds high above the Earth's surface have driven opposite climates in different parts of Europe for the past 700 years and likely much longer, ...

The jet stream, or any wind, is the result of differences in surface temperature. In simple terms, warm air rises, creating low pressure, and cold air sinks, creating high pressure. Wind is the ...

This article explores the meteorological phenomena behind these cold snaps, particularly focusing on the jet stream and its impact on Alberta's weather. The Jet Stream: A Key Player in Weather ...

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 ...
