Off Track: What Causes Turbulence?
Despite the discomfort—and fear—it induces, turbulence is essentially just a “rough patch” caused by wind, thunderstorms, the jet stream, proximity to mountains, and other factors. For travelers it’s an unpredictable foe, like a sudden pothole in the road or summer storm, but it’s so common we try (very) hard to tell ourselves “This, too, shall pass.” Still, stories like this always make us cringe: In late December, an Air Canada flight from Toronto to Shanghai faced a bout of turbulence, so sudden and severe that oxygen masks dropped, blankets flew into the air, and 21 people were injured, reported The New York Times. And then there’s this charming video of a descending plane being “banged to its limits.”
