Bad news for nerve brochures! Thanks to climate change, severe turbulence will worse, scientists
The worst nightmare of every nerve brochure.
And now scientists have warned that severe air turbulence will worse, thanks to climate change.
A heating atmosphere causes discomfort in the jet flow – the narrow current of fast -moving air to obtain the speed of speed of aircraft.
As a result, there will be more sudden changes in the height of the aircraft, throwing people into the plane cabin, causing serious injuries and even death.
In the new articles, experts warn Frpm Reading University about ‘Deep Results for Aviation Safety’ as injuries related to turbulence become more common.
Professor Paul Williams, a working writer, saw serious turbulence events in recent years and serious turbulence events that caused deaths in some tragic cases, ” he said.
‘Pilots may need to keep the seat belt signs longer and suspend the cabin service more frequently during flights.
‘However, the airlines will need new technology to detect turbulence before the stroke and protect the passengers as the sky becomes more chaotic.’

Experts already know how to warm up globally causes discomfort in jet flows, In the upper atmosphere, about 30 feet above the ground, move from west to east around the world.
Since the jet rivers are guided by temperature differences, the Earth’s atmosphere is strengthened and becomes more wavy as they get warmer.
However, the role in the turbulence in the context of long -term tendencies in jet flow behavior and ‘turbulence in the context of climate change is not consumed’.
To learn more, they used the last 26 global climate model to find out how to affect jet flows up to 35,000 Feet – up to 35,000 Feet – up to 2100.
Two common socioeconomic paths (SSP) (SSP) (SSP) showing different ways that the world could change by the Climate Change Panel (IPCC) between governments.
In the middle or ‘middle of the road’ scenario (known as SSP2–4.5), CO2 emissions circulate at the existing levels before they fall into the middle of the face, but do not reach net -refuge until 2100.
In the more serious scenario (known as SSP5-8.5), CO2 emission levels are roughly doubled by 2050 and the average global temperature is higher than 2100 to 4.4 ° C (7.9 ° F).
The worst effects, not surprisingly, occurs for the highest greenhouse gas emission scenario of the SSP5-8.5, which is routinely prevented at any cost of experts.

The Reading University team warns that changing jet flows create stronger ‘wind cutting’ – differences in wind rate at different heights.
Wind cutting may cause rapid changes in flight conditions until sudden losses at height without changing orbit.
SSP2-4.5 scenario, the wind cut will increase by 1600 percent, but the SSP5-8.5 scenario will increase by 27 percent.
And the problem will affect both the northern and southern hemispheres, so which commercial route flys will not be important.
Published Results Journal of Atmospheric SciencesHe warns about an increasing susceptibility for turbulence under climate change ‘.
In other studies, optimizing flights based on the position of a jet flow can help reduce travel time and fuel consumption.
However, the increasing risk of turbulence associated with instability during the jet rivers creates an important difficulty, ” he said.
‘This security vulnerability becomes worse when passengers and crew is not opened, and increases the likelihood of injuries associated with turbulence.’
Not surprisingly, the worst effects occur for the highest greenhouse gas emission scenario of the SSP5-8.5, which experts routinely stimulated.
Previously, the University of Reading Research has found that the severe turbulence has already increased as the world warms up in the last 40 years.
Tens of thousands of planes face serious turbulence each year and encounter an estimated cost of £ 826 million ($ 1 billion) from the costs of injury to the global aviation sector, structural damage and flight delays to aircraft.
And this is not just a terrible experience, potentially deadly; Last year, a British man died of a heart attack triggered by a ‘dramatic drop’ when he met ‘sudden, extreme turbulence’ from London to Singapore last year.
For commercial aircraft, the most problematic turbulence type – open – air turbulence (CAT) is known as ‘invisible’.
The floor is difficult to observe before the trail of a plane using remote detection methods and is challenging for aviation meteorologists to estimate.
Joana Medeiros, a doctoral researcher at the reading university, works together with increased wind cutting and reduced stability, open -air turbulence – to create appropriate conditions for sudden tremors that can shake the plane without warning. ‘He said.
‘In contrast to the turbulence caused by storms, open -air turbulence on the radar cannot be seen, which makes it difficult for the pilots to avoid.’
How does global warming worsen the net air turbulence?
Open -air turbulence, which is invisible and dangerous for aircraft, has increased in various parts of the world.
Researchers at the University of Reading say that this increase took place with global warming increases and two are connected.
Isabel Smith, a doctoral student at the meteorology department of the university, said to Daily Mail: ‘Bil Air Turbulence (CAT) is produced because of the cut of winds, and therefore has a strong connection to jet flows with fast flowing wind bands that spread worldwide.
‘Global warming refers to the rapid heating of the lowest layer of the atmosphere called troposphere.
There are several layers in the atmosphere and the stratosphere on the troposphere.
The troposphere is the place where people live and are the weather, the lowest layer extends up to about six miles.
‘The increase in greenhouse gases usually trapped the heat in the troposphere to be spread to the stratosphere.
Therefore, the stratosphere cools at a rate of tropospheric heating.
‘This creates a strong temperature difference vertically throughout the atmosphere.
‘A stronger vertical temperature gradient will lead to a stronger and more chaotic jet flow.
‘As jet flows strengthen, it becomes more chaotic and unstable, and the number of cats increases.’
