1. Clear-air turbulence

   In meteorology, clear-air turbulence (CAT) is the turbulent movement of air masses in the absence of any visual clues, such as clouds, and is caused when bodies of air moving at widely different speeds meet.The atmospheric region most susceptible to CAT is the high troposphere at altitudes of around 7,000–12,000 metres (23,000–39,000 ft) as it meets the tropopause. Here CAT is most frequently encountered in the regions of jet streams. At lower altitudes it may also occur near mountain ranges. Thin cirrus clouds can also indicate high probability of CAT. CAT can be hazardous to the comfort, and occasionally the safety, of air travelers. CAT in the jet stream is expected to become stronger and more frequent because of climate change, with transatlantic wintertime CAT increasing by 59% (light), 94% (moderate), and 149% (severe) by the time of CO2 doubling.

1. clear-air turbulence

   Clear-air turbulence (CAT) is a form of turbulence in the atmosphere encountered by aircraft when there are no visible cloud formations or other weather indicators. It occurs in clear skies, typically at high altitudes, due to factors such as wind shear, thermal instability, and differences in air pressure or temperature. CAT cannot be detected by conventional weather radar, which often makes it difficult to predict and avoid, making it potentially hazardous for air travel.

CAT can be hazardous to the comfort, and even safety, of air travel. An increase in clear-air turbulence is an expected effect of global warming. In the journal Nature Climate Change Paul Williams of the University of Reading and Manoj Joshi of the University of East Anglia reported moderate to severe transatlantic turbulence would be 40 to 170 percent more frequent in a world that had twice as much atmospheric carbon dioxide as pre-industrial times did.
