If you can predict the path of the jet stream, the upper atmosphere’s undulating river of wind, then you can predict weather — not just for a week or two, but for an entire season. A new study moves toward that level of foresight by revealing a physical link between the speed and location of the jet stream and the strength of the polar vortex, a swirl of air that usually hovers over the Arctic.
