According to scientists, changes in the atmosphere caused by global warming can increase the level of light turbulence by 59, and strong - by 149%.
Surely, almost everyone who has ever flown on a passenger plane is familiar with the unpleasant sensations associated with turbulence: usually the liner begins to shake or it falls into an air hole. Every year in the United States alone, 687 passengers receive minor injuries for this reason, 17 passengers and 38 flight attendants - more serious injuries. There are also 120 minors among the victims.
However, not only passengers are injured, but also planes, which is why flights have to be delayed, preventive examinations and repairs carried out, which costs a pretty penny for air carriers. What is the main reason for these frequent atmospheric anomalies?
The author of a recent study, Paul Williams of the University of Reading, believes that the main reason lies in the shift in air currents in the lower atmosphere.
This means, - he explains, - that the wind speed increases with height, and so it continues up to 10, 000 meters. The fact is that different layers of the atmosphere follow each other and, if the wind shear is too large, then the atmosphere simply does not have time to compensate for the difference in velocities between the layers and the balance in the atmosphere is disturbed. Small disruptions in flows can grow exponentially over time and eventually become chaotic and turbulent.
The scientist, not without reason, believes that climate change is exacerbating this problem, as the contrast between the layers of the atmosphere increases.
