Is Climate Change Making Air Turbulence Worse?

A tragic incident on a Singapore Airlines flight from London to Singapore has reignited concerns about the increasing severity of turbulence, potentially exacerbated by climate change. Geoff Kitchen, a British passenger, lost his life when the flight encountered severe turbulence, illustrating the dangers of increasingly volatile weather patterns at high altitudes.

Understanding Turbulence

Turbulence occurs when irregular air movements cause a plane to roll, pitch, or drop suddenly. There are various causes, from air flowing over mountains to weather-related disturbances like thunderstorms. Clear air turbulence (CAT), which occurs without visual cues and cannot be detected by radar, is particularly hazardous.

Climate Change and Turbulence

Recent studies indicate that climate change is contributing to more frequent and severe turbulence. One study from Reading University found a 55% increase in severe CAT over the North Atlantic between 1979 and 2020. This increase is linked to stronger and more variable jet streams, driven by rising global temperatures.

Impact on Flight Safety

While turbulence is a common occurrence in aviation, the intensification of turbulence due to climate change poses new challenges for flight safety. Severe turbulence can cause significant injuries and fatalities, as seen in the Singapore Airlines incident. It also highlights the need for improved turbulence prediction and detection systems.

Technological Advances

Currently, pilots use radar to detect storm clouds and avoid turbulence, but this technology is ineffective against CAT. LiDAR, a technology similar to radar but using light waves, shows promise in detecting CAT. Although expensive and bulky, advancements could make it a viable option for improving flight safety in the future.

Practical Advice for Passengers

Given the unpredictability of turbulence, passengers are advised to keep their seat belts fastened while seated. This simple precaution can significantly reduce the risk of injury during unexpected turbulence.

Conclusion

The increasing severity of turbulence due to climate change underscores the urgent need for both improved safety measures in aviation and broader climate action. As we continue to experience the effects of a warming planet, addressing these challenges becomes crucial for ensuring the safety and resilience of our global transportation systems.

FAQs

What caused the turbulence on the Singapore Airlines flight? The exact cause is still under investigation, but it is likely due to either clear air turbulence (CAT) or thunderstorms.
What is clear air turbulence (CAT)? CAT occurs when there is a change in wind direction around the jet stream, often difficult to detect as it occurs in clear skies without visual cues.
How is climate change affecting turbulence? Climate change is increasing the frequency and severity of turbulence by altering wind patterns and jet streams.
Can turbulence be predicted? While meteorological organizations provide warnings, current radar systems cannot detect CAT. Technologies like LiDAR could potentially improve detection in the future.
What safety measures can passengers take? Passengers are advised to always fasten their seat belts while seated to prevent injuries during unexpected turbulence.
