Climate change will add turbulence

April 11, 2013. Change climate by mid-century will make significantly more frequent in cases of aircraft hitting zone of turbulence in the atmosphere, which will increase the number of injuries, aircraft damage and increased economic losses of about $ 150 million, told reporters Sex Williams (Paul Williams) from the National Center for Atmospheric Science at the University of Reading, UK.

"We can expect that by mid-century, the average force of cases will increase the turbulence of 10-40% compared to pre-industrial values, with the proportion of the atmosphere, where at any time there is turbulence will increase from 40% to 170%," — said Williams, presenting the results of his research at the European Geosciences Union in Vienna.

Zone of turbulence in the clear sky, where the air flows "throw" airliner up and down — still have not solved the problem for airlines, because there is no reliable way to detect them in advance. Existing forecasting methods are based mainly on the reports of the pilots. According to experts, the passing zones of turbulence takes about 3-4% of the time of flight.

Uilms and his colleague Manoj Joshi (Manoj Joshi) from the University of East Anglia with the help of calculations on a supercomputer for the first time tried to figure out how to change Climate impact on the aviation industry. They simulated the atmospheric conditions during the winter months at a time when the concentration of carbon dioxide will double compared to pre-industrial levels — this value may reach the level of CO2 in the 2050s.

As a result, scientists have a picture of the distribution zones of instability in the atmosphere, where it turned out that one of these "spots" are almost constantly on one of the busiest air routes of the world — over the North Atlantic, where the transit routes from Europe to the United States and Canada. Williams notes that because of this, airlines will have to change routes, and therefore spend more fuel and incur losses.

Buckle: turbulence growing year by year

April 13, 2013. Planes will soon be harder to shake than ever before. Ecologists from the University of Reading have found a new reason to turbulence. Carbon dioxide leads to increased temperature and increased eddy currents.
