Topic: Jet stream study confirms aircraft turbulence risk from climate change

+Cook My Own Breakfast !!IpftyHSqdT6.8 years ago #53,614

Climate change is having a greater impact on the jet stream than previously thought, according to a new study published in Nature.

Scientists at the University of Reading have discovered that the jet stream has become 15 percent more sheared in the upper atmosphere over the North Atlantic since satellites began observing it in 1979.

Because wind shear generates turbulence, the new study provides the first observation-based evidence to support previous Reading research that human-induced climate change will make severe turbulence up to three times more common by 2050-80.

I don't think so :)

I started posting these only recently. And I trying to post genuinely interesting items ;)

News spam was outdated info, not current year stuff

@OP
> "Indications of a stronger jet stream in the future suggest the upper-level tug will eventually win out. This would also affect airlines by increasing flight times from Europe towards the US and speeding up flights the other way."

Does it work that way?

Well, yes. I mean, even now flying in one direction is faster than in the other. Also due to the rotation of the planet.

I am not an expert in this, but I believe that this is what he explains earlier in the article:

Over the last four decades, temperatures have risen most rapidly over the Arctic, whilst in the stratosphere—around 12 km above the surface—they have cooled. This has created a tug-of-war effect, where surface temperature changes act to slow the jet down, while temperature changes higher up act to speed it up.
