London - If you’re already a nervous flyer, then this news won’t help much.
Turbulence on transatlantic flights is likely to increase in both length and intensity by 2050 because of climate change, scientists say.
Increased levels of carbon dioxide are strengthening and altering the position of fast-flowing air in the upper atmosphere – the jet stream – moving it towards flight routes.
Passengers on flights from London to New York currently experience ten minutes of turbulence on average, according to the research team from the University of Reading. By 2050, according to their computer modelling, that figure is expected to double 20 minutes. And the turbulence itself is likely to be up to 40 percent stronger.
Lead researcher Paul Williams said: “Sadly, this will mean that the fasten seat belt sign will be on for longer on each flight – and there will be more spilt drinks too.
“Hundreds of people are injured each year as a result of turbulence, mostly airline crew who spend much of the flight not strapped in their seat. The total annual cost is around £100-million globally.
“It is certainly plausible that there will be more injuries to passengers and crew by the middle of the century, compared to now.”
He added: “One thing that many people don’t realise is that climate change affects the upper atmosphere, changing the winds known as the jet stream. It is making it stronger and changing its position, moving it closer to commercial flight routes.”
The team looked at “clear air” turbulence, which occurs without warning and cannot be detected by on-board equipment.
The study was published in the journal Nature Climate Change. - Daily Mail
