And here you go, it's plotting a week of minimum/average/max windspeeds at altitudes up to 30Mm (10Mm is ~30M ft), over the FWD station.

Delta Air Lines flight from Seattle to Shanghai mysteriously turned back and returned to the United States nearly six hours into what should have been an 11 hours flight to China. The mid-air flight cancellation has resulted in a rebuke from the Chinese consulate in San Francisco which said on its WeChat account that it had “lodged a protest” with the airline.
Delta has since cancelled its planned service from Seattle to Shanghai until December 30 at the earliest but it remains unclear why the airline was forced to turn around in the first place.
According to witnesses on the flight, the pilot suggested that a change in entry requirements had been announced by the Chinese authorities at some point after takeoff. There was a fear that the passengers were no longer eligible to enter China so the only alternative was to fly back to Seattle.
Local Chinese media have been told by Shanghai airport officials that entry rules have not changed in some time and no sudden change had been made after DL287 departed. Passengers onboard the flight were so perplexed that they didn’t believe Delta staff and police were allegedly called once the aircraft arrived back in Seattle.

it was the export version, not for domestic consumption.
LOL!
Whoa - my first guess too...
Excellent example...
No, the high altitude compressor stalls take care of that...
“ Rough ride with that tail wind?”
A tail wind does not equate to a rough ride. Pilots are always looking at winds aloft to find a tail wind which saves a lot on fuel in addition to an earlier arrival time.
Absolutely smooth ride, my wife even asked me if the airplane was shuttering because we are going so fast. It’s all relative, with 180 knot tail wind the airplane is still flying in the same relative forward air speed. Big difference in ground speed however! I’ve only had one other flight in the last 15 years during a crossing where we kept the tail wind from takeoff to landing. Normally we get up around the Aleutian chain and there is what could be considered the doldrums were you have basically no wind.
The jetstream varies based on Coriolis effect, surface friction and tropopause. From day-to-day it changes and our flight plan is fully automated to make sure that we receive the maximum benefit of the wind. While avoiding bad weather of course!
Space is above us so best to keep the nose down! Geez, tough crowd!
I caught rides with tail winds over the Rockies and mountain wave action.
Was unpleasant to say the least.
But your point is well taken
Thanks for the info. You have the coolest job. Thanks for answering my simplistic and rookie questions.
Yes, that is turbulence which is different than winds aloft but there can be some correlation.
Retired ATC here.
ATC
My respects. That’s a stress job.
It sounds neat. And I guess going into the jet stream you try to stay below the fastest wind and then it is a tossup between the headwind and the denser atmosphere. I imagine there are all kinds of calculations for things. If you have a picture of your project, please post the image. It sounds interesting.
Mystery of Why Delta Air Flight to China Turned Back to Seattle More Than Half Way Through Flight>>>>>>>>>>>
Its quite simple.( Heavy Sarc.)
They discovered their cargo load was a collection of Hunter Biden’s paintings for which the Chinese Communists had paid over 2 Billion dollars to the Biden family mafia.
The quid pro quo was an exchange for Cheater Joe’s guarantee that the USA would stand down when Red China invades Taiwan.
When the pilots, both Trump supporters, discovered what cargo was on their air craft, they turned for home immediately.
While inspecting the cargo they also discovered the load of Hunter’s paintings included 200 Virginia Hams bound for Beijing, the dessicated corpse of Eric Swalwell’s Chinese House Maid that smelled of San Fran Nan’s medicinal street hashish, and a trash can with several pistols in it along with a couple of lap tops.
The plot against Taiwan thickens.Its time for Jamzu Bondo-OO7.
Meanwhile, new alternate shipping arrangements have been made for the cargo routed through Queensland , Australia.
That’s neat. I didn’t realize that there is so much wind under 20000 ft.
Your job is also stressful.
As you know, everyone handles stress differently.
For me…. The busier it got, the quicker the day past and I liked it!
