Thirty years ago, atmospheric scientists began to notice a worrisome trend. They knew that turbulence from storms increases in summer, when hotter and more humid air rises to form thunderheads.

That temperature difference drives the jet stream, which creates turbulent eddies and wind shear as it rushes through slower bodies of air. But, on top of these seasonal swings, there seemed to be an over-all trend as well: Earth’s atmosphere was getting rougher.
