The Jet Stream map shows today's high wind speed levels and jetstream directions. Jet streams are fast flowing, relatively narrow air currents found in the atmosphere around 10 kilometers above the ...

Will the Pacific jet stream or the polar vortex dominate November's weather? A 'blowtorch pattern' sets up, but for how long?

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 ...

If you’ve ever heard a meteorologist mention the jet stream and thought, “Okay… but what does that actually mean?” You’re not alone. It’s one of the most important drivers of weather across the United ...

A new study challenges the idea that climate change is behind the erratic wintertime behavior of the polar jet stream, the massive current of Arctic air that regulates weather for much of the Northern ...

Heavy precipitation, wind storms, heat waves—when severe weather events such as these occur they are frequently attributed to a wavy jet stream. The jet stream is a powerful air current in the upper ...
