Q: Image caption Planes are already encountering stronger winds, scientists say 
  
 Flights across the North Atlantic could get a lot bumpier in the future if the climate changes as scientists expect. 
  
 Planes are already encountering stronger winds, and could now face more turbulence, according to research led from Reading University, UK. 
  
 The study, published in Nature Climate Change, suggests that by mid-century passengers will be bounced around more frequently and more strongly. 
  
 The zone in the North Atlantic affected by turbulence could also increase. 
  
 Reading's Dr Paul Williams said comfort was not the only consideration; there were financial consequences of bumpier airspace as well. 
  
 "It's certainly plausible that if flights get diverted more to fly around turbulence rather than through it then the amount of fuel that needs to be burnt will increase," he told BBC News. 
  
 "Fuel costs money, which airlines have to pay, and ultimately it could of course be passengers buying their tickets who see the prices go up."

 Dr Williams was presenting his research here in Vienna at the European Union Geosciences (EGU) General Assembly. 
  
 It was undertaken with Dr Manoj Joshi from the University of East Anglia. 
  
 The scientists concentrated their investigation on the North Atlantic corridor, which some 600 flights cross each day to go between the Americas and Europe. 
  
 They used a supercomputer to simulate likely changes to air currents above 10km in altitude, such as the fast-moving jet stream. 
  
 There is evidence to suggest this has been blowing more strongly, and under some scenarios could be prone to more of the instabilities associated with turbulence as the Earth's climate warms.

 Williams and Joshi compared what was essentially an unchanged ("pre-industrial") climate with one that contained double the carbon dioxide. This could happen in the 2050s on present trends. 
  
 The modelling suggested the average strength of transatlantic turbulence could increase by between 10% and 40%, and the amount of airspace likely to contain significant turbulence by between 40% and 170%, where the most likely outcome is around 100%. In other words, a doubling of the amount of airspace affected. 
  
 "The probability of moderate or greater turbulence increases by 10.8%," said Dr Williams. 
  
 "'Moderate or greater turbulence' has a specific definition in aviation. It is turbulence that is strong enough to bounce the aircraft around with an acceleration of five metres per second squared, which is half of a g-force. For that, the seatbelt sign would certainly be on; it would be difficult to walk; drinks would get knocked over; you'd feel strain against your seatbelt." 
  
 The Nature Climate Change study is said to be the first to examine the future of aviation turbulence. 
  
 Figures are hard to come by but the costs of air turbulence in terms of injuries, plane damage and post-incident inquiries are thought to be in the region of $150m (£100m) a year. 
  
 Detecting clear-air turbulence (unstable air in clear blue skies) by remote sensing is difficult. 
  
 Currently, pilots rely a lot on reports from planes that have already made the journey across the Atlantic earlier in the day for information about probable flight conditions.

Commercial aircraft encounter moderate-or-greater turbulence tens of thousands of times each year worldwide, injuring probably hundreds of passengers (occasionally fatally), costing airlines tens of millions of dollars and causing structural damage to planes1,2,3. Clear-air turbulence is especially difficult to avoid, because it cannot be seen by pilots or detected by satellites or on-board radar4,5. Clear-air turbulence is linked to atmospheric jet streams6,7, which are projected to be strengthened by anthropogenic climate change8. However, the response of clear-air turbulence to projected climate change has not previously been studied. Here we show using climate model simulations that clear-air turbulence changes significantly within the transatlantic flight corridor when the concentration of carbon dioxide in the atmosphere is doubled. At cruise altitudes within 50–75° N and 10–60° W in winter, most clear-air turbulence measures show a 10–40% increase in the median strength of turbulence and a 40–170% increase in the frequency of occurrence of moderate-or-greater turbulence. Our results suggest that climate change will lead to bumpier transatlantic flights by the middle of this century. Journey times may lengthen and fuel consumption and emissions may increase. Aviation is partly responsible for changing the climate9, but our findings show for the first time how climate change could affect aviation. |||||

Already annoyed by airplane turbulence and flashing seat-belt signs? Those bumpy rides will get significantly worse over the North Atlantic in years to come, according to a new study. A British research team has found that climate change will probably intensify North Atlantic winds that were already growing stronger. That means flights between the Americas and Europe will only get bumpier or be forced to take costly detours around turbulent areas, the BBC reports. "Fuel costs money, which airlines have to pay, and ultimately it could of course be passengers buying their tickets who see the prices go up," said a co-author of the study. Using a supercomputer, the researchers found that by the 2050s, North Atlantic turbulence could grow by 10% to 40%, and the area of turbulent winds could expand by up to 170%.
