Severe turbulence on flights may triple by 2050: Study

Prime News, International (London), October 4:- Severe mid-flight turbulence on routes around the globe may triple by 2050 due to climate change, increasing the risk of injury to passengers and crew, scientists have warned today. According to the first global projections of in-flight bumpiness, flights all around the world will be encountering lots more turbulence in future.
The study led by the University of Reading in the UK analysed supercomputer simulations of the future atmosphere with a focus on clear-air turbulence, which is particularly hazardous because it is invisible.
The expected turbulence increases are a consequence of global temperature changes, which are strengthening wind instabilities at high altitudes in the jet streams and making pockets of rough air stronger and more frequent, said the researchers who include an Indian-origin scientist.
The study, published in the journal Geophysical Research Letters, calculated that climate change will significantly increase the amount of severe turbulence worldwide by 2050-2080.
Severe turbulence involves forces stronger than gravity, and is strong enough to throw people and luggage around an aircraft cabin.

“The study is another example of how the impacts of climate change can be felt through the circulation of the atmosphere, not just through increases in surface temperature itself,” said Manoj Joshi, a senior lecturer at the University of East Anglia in the UK.

Flights to most popular international destinations are projected to experience the largest increases, with severe turbulence at a typical cruising altitude of 39,000 feet becoming up to two or three times as common throughout the year over the North Atlantic (180 per cent), Europe (160 per cent), North America (110 per cent), North Pacific (90 per cent) and Asia (60 per cent).
