Which term refers to increased aircraft turbulence caused by changes in atmospheric conditions linked to climate change?

• A. Extreme weather events
• B. Clear-air turbulence
• C. Ecosystem volatility
• D. Climate-related investment

Answer: (B)

Clear-air turbulence describes turbulence that happens in clear skies, usually high in the atmosphere, and is driven by wind shear and rapid changes in atmospheric flow. Climate change can alter upper-atmosphere conditions—changing jet-stream intensity and patterns, temperature gradients, and wind shear—which can make clear-air turbulence more frequent or stronger. That link to atmospheric state changes, rather than visible weather or clouds, is why this term best fits “increased aircraft turbulence caused by changes in atmospheric conditions linked to climate change.” Extreme weather events refer to storms and other phenomena, ecosystems and investments aren’t about flight turbulence, so they don’t capture this specific aviation-related effect.
