Key Takeaways
• Severe clear-air turbulence on North Atlantic flights increased 55% from 1979 to 2020, driven by climate change.
• Strong wind shear near jet streams, intensified by global warming, makes clear-air turbulence harder to predict and avoid.
• Airlines must invest in new forecasting technology as future turbulence events could double or quadruple without emission cuts.
Flights Could Get Bumpier: Scientists Warn of More Clear-Air Turbulence
Recent scientific reports paint a clear picture: flights around the world may soon feel bumpier as the skies change. The reason lies in a growing problem called clear-air turbulence, which is expected to become much more common in the years ahead. This change is closely tied to climate change and its effect on jet streams above the Earth. Scientists have shared strong evidence for these changes, pointing out why travelers, pilots, and the aviation industry need to pay close attention.
What Is Clear-Air Turbulence and Why Is It Different?
Clear-air turbulence, often called CAT, happens at high altitudes where planes cruise, usually in areas without clouds or storms. This makes it very hard to see coming because onboard radar systems can’t spot it. CAT occurs when there are sudden changes in wind speed or direction. These wind changes, known as wind shear, are often found near jet streams.
Jet streams are like fast-moving rivers of air high up in the sky. When wind shear is strong, the calm ride you expect on a plane can turn rough without warning. Unlike turbulence from thunderstorms, mountains, or nearby weather, clear-air turbulence can surprise both pilots and passengers when skies appear perfectly blue.
Recent scientific studies highlighted by VisaVerge.com show that this invisible danger is becoming a real headache for airlines and passengers alike. Let’s look more closely at what researchers have discovered.
Strong Evidence Points to More Turbulence Ahead
Historical records and careful analysis by scientists give us a clear story: clear-air turbulence has been growing steadily since at least the late 1970s. One place where this problem stands out is over the North Atlantic Ocean, which is the world’s busiest route for transatlantic flights.
- From 1979 to 2020, severe clear-air turbulence on North Atlantic routes increased by 55%.
- Similar increases have been recorded in other busy skies, including over the United States 🇺🇸, parts of North Africa, East Asia, and the Middle East.
But that’s not all. When scientists use computer models to guess what the future holds, the news gets even more serious. If temperatures keep rising as they have been, the number of very bad turbulence events could double—or even quadruple—on some major international routes by the end of this century.
One of the biggest reasons for this increase is the effect of global warming on wind patterns. Wind shear at cruising levels, measured by satellites, has already grown about 15% since satellites started watching closely. By 2100, if our current emissions stay high, this number could jump to as much as 29%. For pilots and airlines, this means more work avoiding rough patches, and for passengers, rougher rides ahead.
How Climate Change Makes Jet Streams More Unstable
You might wonder what climate change has to do with turbulence. The answer lies in how global warming disrupts the balance of temperature in our atmosphere.
- Climate change leads to larger differences in temperature between different parts of the atmosphere, especially near the poles.
- Melting ice at the North and South Poles speeds up these temperature changes.
- As these differences grow, jet streams—those fast, flowing air currents—become stronger and more unstable.
Jet streams are important because they set the pattern for much of the world’s weather and guide many international flights. When the boundaries between warm and cold air move around more wildly, the result is more vertical wind shear. Clear-air turbulence forms easily in these bouncing, twisting stretches of air.
Professor Paul Williams from the University of Reading summarized it well: “Essentially, global warming is creating larger temperature differences in the atmosphere… Those differences intensify wind shear in jet streams leading to more frequent and intense clear-air turbulence.”
So, every degree that the planet heats up makes these high-altitude winds a bit more dangerous for planes to cross.
What Does This Mean for Passengers?
If you’re a frequent flyer, or planning an overseas trip, these scientific findings matter for you. More clear-air turbulence means you’re more likely to experience bumpy flights, even on days when the sky looks clear and calm through the window.
Here’s what current trends suggest:
- More turbulence means more rough patches on even the most popular and normally smooth routes.
- Aircraft are built to handle strong bumps, and pilots are trained to fly safely through sudden choppy air. For the most part, flying remains safe.
- However, as turbulence events become more intense and frequent, injuries to passengers and crew may rise, especially when people are not buckled in.
There have already been several news stories about flights forced to land early or even emergencies caused by unexpected, severe clear-air turbulence. Most passengers walk away without harm, but the number of injuries has been creeping up.
For anyone worried, the best advice is simple: keep your seatbelt fastened whenever you’re seated, not just when the “fasten seatbelt” sign is on. It’s a small step that can make a big difference if unexpected turbulence hits.
How Airlines and Pilots Are Responding
Flying through the sky is never the same every day. Pilots rely on many tools to stay ahead of rough air, but clear-air turbulence presents special challenges.
Traditional weather radar is great for spotting storms and thick clouds, but it can’t pick out invisible CAT. Here’s what pilots and airlines do to try and avoid the worst bumps:
- Pilots get weather briefings before takeoff that highlight possible rough patches, especially in areas where CAT is known to happen.
- During flights, pilots report back on rough spots in real-time. These reports, called PIREPs, get shared with other pilots flying in the same region.
- Airlines use special forecasting tools and networks, like IATA’s Turbulence Aware system, which collects turbulence data from thousands of flights.
Even with these efforts, scientists agree that pilots can’t detect or avoid all clear-air turbulence because it is often invisible. Airlines may have to make changes, like adjusting flight altitudes more often or flying different routes to sidestep hotspots of rough air.
These changes could mean slightly longer flight times or different arrival patterns in some cases. For airlines, it may also lead to higher operating costs as they use more fuel or need more maintenance after repeated rough rides.
Why Better Technology Matters
Because clear-air turbulence is sneaky, there’s a growing demand for better technology to warn pilots and passengers more effectively. Researchers believe a few changes could help make flying smoother in the years ahead:
- Improved forecasting systems can spot likely CAT spots before a plane gets there.
- Better sharing of real-time turbulence data between different airlines and countries can help build a clearer picture of the skies.
- New seatbelt policies or passenger alert systems can keep travelers safer during unpredictable bumps.
Yet, no matter how much technology improves, experts caution that it won’t stop turbulence completely. As climate change keeps changing our atmosphere, some rough patches in the sky are here to stay. Investments in safer planes and better training will help, but nature still controls much of what happens miles above the ground.
Wider Effects on the Aviation Industry
This growing problem isn’t just about bumpy rides or nervous travelers. More clear-air turbulence affects many parts of the aviation industry, including how airlines plan flights and how airports run day to day.
- Airlines may need to spend more time and money mapping out safer, less bumpy routes, especially on popular transatlantic flights.
- More maintenance may be required for aircraft that go through strong turbulence frequently.
- Flight delays and scheduling issues could increase if pilots need to detour often or wait out bad turbulence patches.
- Air traffic controllers and airport planners may need to coordinate closely with more pilots requesting altitude or route changes during flights.
There are also potential effects for airlines’ fuel use and greenhouse gas emissions. Flying around turbulence, instead of in a straight line, may use extra fuel. This could make it harder for airlines to meet environmental goals, especially as they try to cut their own impact on climate change.
Global “Hotspots” for Turbulence
Some flight regions face greater challenges than others. So far, the biggest increases in clear-air turbulence have been seen over:
- The United States 🇺🇸
- The North Atlantic (most common transatlantic routes)
- North Africa 🇳🇬
- East Asia 🇨🇳
- The Middle East 🇸🇦
These places have busy skies, with hundreds of flights daily. For travelers crossing these regions, it’s likely that rough patches will become even more common in the years ahead.
Global warming is expected to worsen turbulence in the Northern Hemisphere especially, as big differences in temperatures drive jet streams to act more wildly.
What’s Next? The Long View
Scientists, pilots, and airline leaders largely agree: unless greenhouse gas emissions are cut quickly and sharply, clear-air turbulence will keep getting worse. Advanced models suggest that by the late 21st century, some routes might see twice as many or even four times as many severe turbulence events as today.
This doesn’t mean flying will become unsafe, but it does mean that comfort may take a hit. Ongoing research aims to keep passengers safe and airlines running smoothly.

Final Thoughts
Flights may not be as smooth in the coming decades as they once were. The rise in clear-air turbulence is a stark reminder that the effects of climate change reach up into the skies. Stronger jet streams and more wild temperature swings mean bumpier flights—sometimes with very little warning.
The aviation industry is gearing up for the challenge, investing in new technology and better training. For passengers, staying buckled in and following crew directions are the best defenses. While air travel remains one of the safest ways to get from place to place, a little extra caution and care go a long way.
Scientists will keep studying how climate change, jet streams, and wind patterns affect our skies. In the meantime, keeping greenhouse gas emissions as low as possible remains the best hope for smoother flights in the future.
As reported by VisaVerge.com, the world’s airlines and passengers alike should expect to adapt to a new era of flying—one where clear-air turbulence becomes a normal part of the journey, thanks to the ongoing changes in our climate and atmosphere.
