The post Winter Weather Is Moving West: How The Polar Vortex Is Rewriting America’s Cold Map appeared first on Study Finds.
Polar vortex patterns explain shifting US winter cold despite warming climate
Despite a warming climate, bone-chilling winter cold can grip parts of the U.S. In a study appearing in Science Advances, researchers found that two specific patterns in the polar vortex, a swirling mass of cold air high in the stratosphere, steer extreme cold to different regions of the country. One pattern drives Arctic air into the Northwest U.S., the other into the Central and Eastern areas.
Predictions of a weaker polar vortex this winter could mean more extreme weather
The United States could be headed for some extreme weather this winter. That’s the early prediction from Severe Weather Europe, a website that tracks weather patterns around the globe.
Although the Earth is warming up as a whole due to climate change, in parts of the USA increasingly icy winters occur with extreme snowfall and life-threatening low temperatures. Climate researchers have now found out which factors contribute to this local extreme weather. According to this, two specific patterns of the polar vortex are responsible high above the Arctic. They determine when and where a [...] The post Why did the US last experien…
