Is Clear Air Turbulence becoming more common?

Re: Is Clear Air Turbulence becoming more common?
#142Most of the recent widely publicized CAT injuries have been on long distance flights between Europe and South Asia. One thing that’s happened in the past couple of years along that air corridor is the squeezing of flight paths out of Ukrainian, Russian, Israeli, and Afghan airspace. Planes taking more circuitous routes, giving them less options to avoid weather conditions, much of the flight over hot mountainous terr…
Weird that this is the top-rated comment, as it's directly contradicted by the heat maps in the article, which show increases in CAT all over the globe, in many places that are not routes between Europe and South Asia. (Also consider that the principal question the article tries to answer is not "are there more CAT incidents?" but simply "is there more CAT?") I glanced at a few current (as of today) routes, e.g. CDG-…

The reason it is top-rated is because it sounds extremely reasonable. This is enough for most people.
I am not judging on whether the comment is correct or not, just answering why it is top-rated. I find nothing weird about it.

Jet stream is also driven by temperature differences, like basically all weather. Heat engines.
It’s a heat engine but more than just temperature changes are occurring. “The new study, by University of Chicago Professor Tiffany Shaw and NSF NCAR scientist Osamu Miyawaki, uses climate models to show that climate change intensifies this density contrast because moisture levels for air above the tropics will increase more than above the poles.” https://news.ucar.edu/132935/jet-stream-winds-will-accelerat... .
I guess it's like someone putting water on the coals in a sauna and the people feel a huge wave of heat due to the increased heat transfer, even though they've literally cooled down the coals.

> The article exists because of several recent high profile CAT incidents. Yes, but the article doesn't claim your narrowing of the scope, that it's mostly just between Europe and Asia.
Where did he claim this? > Most of the recent widely publicized CAT injuries have been on long distance flights between Europe and South Asia. > Planes taking more circuitous routes ... could be a contributing factor to increasing incidents of dangerous turbulence affecting flights
The whole point of the argument was that changes to routing in the part of the world was contributing to the increases we're seeing. Back the fact that we're seeing increases all over the world suggests that we'd also see increases in Europe/South Asia even without the current conflicts. Therefore it seems like a distraction from the real mystery to focus on it.

#146Shameless plug here. I work at SkyPath ( https://skypath.io ) we monitor and collect CAT data from 1000's of flights in real time and predict CAT events with the help of an AI model. Pilots are extremely happy with our solution, we signed several of the major airlines in US and have active evaluation programs with several others.
I see the site claims to save fuel, is this in the form of providing routing? I assume that patching data needs to get in to the autopilot system at some point, how does that work?
Re: Is Clear Air Turbulence becoming more common?
#147I can't tell if it's just me or something with flights but recently when I take flights I get an intense headache that isn't similar to other headaches.
For a few months, I used to have headaches too in the last 10 minutes before landing of every flight. Since I had a surgery for my sinusitis a few months before, I thought it was because of some air pressure buildup in my maxillary sinuses that wasn't returning to normal air pressure fast enough. Now every time I am close to landing I make sure the air circulates through both nasal cavities very well and I haven't ha…
Interesting! I have been having issues with my sinuses. I wonder if that is the cause.

Doesn't a comment automatically rise to the top if there's lots of discussion below it?

I've read something more of the opposite before: posts with lots of comments risk being down weighted unless they've received a lot of upvotes. Supposedly something to do with wanting to avoid lower value content which is attracting a large amount of discussion anyways.
I've never heard of anything of this nature regarding comments though.

#150"Are Clear Air Turbulence events happening more often?
In a word, yes. Recent studies have shown a significant increase in the frequency and intensity of CAT conditions over the past few decades. This increase is linked to several factors, most notably climate change."
We've had this invisible hand of the market to regulate ourselves. Now we have the invisible hand of the planet. It won't be a fun ride either.
