And it’s going to be bumpy for a long time.
Severe clear-air turbulence (CAT) has already become more common, according to a study published in the journal Geophysical Research Letters last week. On a typical flight route over the North Atlantic, there was a 55 percent increase in clear air turbulence between 1979 and 2020. While the increase in turbulence was the most pronounced over the US and North Atlantic, the study also found significantly more turbulence along popular routes over Europe, the Middle East, and South Atlantic, and Eastern Pacific.
