Climatic change to cause frequent flight turbulence

Flight turbulence is going to be quite common in future b in the skies above the North Atlantic due to changes in wind shear as a result of human-caused climate change.

The turbulence research focuses on the main driver of mid-latitude jet streams: The temperature difference between the equator and the North Pole, which powers what is known as the thermal wind.

In general, the greater the temperature contrast between the equator and the pole, the stronger the jet stream will blow from west to east across the North Atlantic, steering and energizing storm systems along with it.

The new study, by meteorologists at the University of Reading, finds that at higher altitudes, including the lower stratosphere over the pole, temperatures have been declining in response to rapid Arctic climate change.

Meanwhile, the upper troposphere above the equator features increasing average temperatures. This means the temperature contrast is increasing at these altitudes.
