Air quality remains poor in parts of Canada as wildfire smoke travels along the jet stream — with Europe now in its path.

The smoke floating over the border shared between America and Canada is now impacting air quality in states as far south as Texas, AirNow's data shows. The EPA has declared the air quality in states ...

In recent months, the jet stream’s patterns trapped and stalled a ridge of high pressure over northern Canada, which caused a heat wave and primed the landscape for the wildfires that later sent ...

A faster jet stream could contribute to more extreme weather like hail, tornadoes and flash floods. And even downslope high wind events like the one that led to Marshall Fire in December 2021.

The Arctic chill draining across the U.S. over the past several weeks will change course as we turn the page into February. January featured unusual jet stream dynamics across North America, a ...

Strong jet streams across the Atlantic are seeing passenger airplanes knock more than an hour off their flight times, as they hit speeds of 761 mph – the speed of sound. However, they’re not ...

A multi-century climate record suggests that current Atlantic jet-stream variations are not the cause of an increase in extreme weather events. A multi-century climate record suggests that current ...

Instead, the jet stream appears to have undergone natural—though sporadic—periods of "waviness" since before the effects of climate change were considered significant, the researchers report.

What made these flights truly exceptional, was the powerful influence of a jet stream, a high-altitude, fast-moving air current that can significantly impact an aircraft's speed and efficiency.
