Rising Clear Air Turbulence: A Looming Threat to Aviation

Instances of clear air turbulence in the Northern Hemisphere have surged by 60-155% from 1980 to 2021, posing increased risks to aviation. Researchers attribute this rise to global warming, which intensifies jet streams and vertical wind shear. Predictions indicate that this invisible turbulence will become more frequent, especially over regions like North Africa, East Asia, and the Middle East.

Clear air turbulence, a gravity-defying force increasingly encountered by planes, has surged by 60-155% between 1980 and 2021 in the Northern Hemisphere, according to a new study.

Researchers warn that as the climate warms, the frequency of this unpredictable turbulence—triggered by intensified jet streams—is set to rise, impacting aviation safety disproportionately in northern mid-latitude regions.

Commercial aircraft cruising at altitudes of 32,000-39,000 feet cross paths with these turbulent jet streams, leading to dangerous 'vertical wind shear.' Recent severe incidents, including a deadly Singapore Airlines flight, underscore the growing peril.
