Atmospheric researchers have developed a climate model that can accurately depict the frequently observed winding course of the jet stream, a major air current over the Northern Hemisphere. It demonstrates that the jet stream's wavelike course and subsequent extreme weather conditions like cold air outbreaks in Central Europe and North America are the direct results of climate change.
