New theory finds 'traffic jams' in jet stream cause abnormal weather patterns

A study offers an explanation for a mysterious and sometimes deadly weather pattern in which the jet stream, the global air currents that circle the Earth, stalls out over a region. Much like highways, the jet stream has a capacity, researchers said, and when it’s exceeded, blockages form that are remarkably similar to traffic jams — and climate forecasters can use the same math to model them both.
