Clear air turbulence happens when a jet stream of air tosses an airplane around in the sky. It can be dangerous, because it cannot be predicted, and can catch a flight off guard when some passengers aren’t wearing their seatbelts.

During turbulence, most of the time if passengers are wearing their seatbelts, no one is injured.

But recently there have been more reported cases of air turbulence that has led to injuries and even hospitalization of passengers.

Clear air turbulence happens when a jet stream of air tosses an airplane around in the sky.

It can be dangerous, because it cannot be predicted, and can catch a flight off guard when some passengers aren’t wearing their seatbelts.

A recent study says that one of the effects of climate change is that there will be more unpredictable jet streams, and therefore, more turbulence during flights.

John Hansman, a professor of aeronautics and astronautics at MIT is quoted as saying: “The problem with clear air is it can’t reflect off anything so it’s difficult to make those measurements. Right now there are no operational systems that can remotely detect clear air turbulence.”

Results of the study show that the occurrence of turbulence over the Atlantic Ocean is expected to double by the year 2050 because of increased jet stream wind activity.
