Reports of flight turbulence are not unusual, but have become more frequent and more serious in the last few years.
Death due to turbulence is also very rare. According to BBC News, there are no official death data caused by turbulence, but it is estimated that since 1981 have been about four deaths.
But the injury tells another story. Passengers captured in the incidents of severe turbulence often end with bruises, wounds and broken bones. If they are lucky, it’s all they last.
According to the annual security report of the International Civil Aviation Organization, it was caused by turbulence caused by turbulence caused by passengers flying during 2023, which is almost 40% caused by turbulence.

In the US alone, there were 207 serious injuries – where the individual was admitted to the hospital for more than 48 hours – since 2009, BBC News reported official data from the National Shipment exhibition. There were 166 crews and maybe not settled.
But why are turbulence incidents more common now?
According to BBC News, citing experts, air transport could become more crafty because the climate change will shift atmospheric conditions; Temperature changes and shifting wind formulas in the upper atmosphere are expected to increase the frequency and intensity of serious turbulence.
“In the next few decades, we can expect double or triple the amount of serious turbulence around the world,” said Professor Paul Williams, an atmospheric scientist from the University of Reading.
“Every 10 minutes of heavy turbulence can now increase to 20 or 30 minutes,” he added.

3 key causes of turbulence:
- Convective: clouds or thunderstorms
- Orographic: the flow of air around mountain areas
- Clear-Air: Changes in the direction or speed of wind
While each type could bring serious turbulence, convective and orographic is often more prevented; This is a clear air turbulence that cannot be seen and seemingly based on now.
Climate change controls turbulence
Climate change is the main factor in increasing both convective and clean turbulence.

Convective turbulence
Climate change and thunderstorms have a complex relationship; A warmer atmosphere can maintain more moisture and that extra heat and moisture combine to create more intense thunderstorms.
Convective turbulence is created by the physical process of air climb and falling in the atmosphere, specifically in the clouds. And there are never more violent concepts up and down than in cumulonimbus or storm clouds.
One American study, which was published in a scientific journal in 2014, has shown that to increase the global temperature by 1 ° C, the lightning strikes will increase by 12%.

Turbulence with clean air
The BBC news report has said that clean air turbulence is caused by disturbed air in the current and around the stream. The wind speed in the current, which moves from west to east through the Atlantic, may vary from 160 mph to 250 mph.
To the north there is colder air and warmer air to the south. This temperature difference and wind change are useful for the aircraft as a tail to save time and fuel. But it also creates turbulent air.
“Climate change warms air to the south of the current of the current more than air to the north to reinforce the temperature difference,” explains Prof Williams. “Which in turn controls a stronger current of the current.”
