What's magical about the Earth's wind system is that there is an altitude where the wind speed is basically zero, so certain types of balloons can "hover" over one spot for months at a time.

Thanks, I didn't know that... makes sense that if the a high velocity wind at one elevation and there's another one in the opposite direction at a higher elevation that there's a layer between where this would approach zero. Until looking at the app, I didn't know that there was a layer of high velocity wind in the opposite direction. I only knew of the jet stream.

They started learning about Jetstream's and the like when they Nuked Japan.

Concorde used to go completely different routes to everyone else because it was so much higher.

What I want to know is why when I need to get home early from work I always get a head wind going and then a head wind coming back?

BTW I wouldn't say its zero although it maybe horizontally compared to the main body of air moving. Its a shear zone and is quiet often like a washing machine. You will get a change in temp and then your in it and all hell lets loose.
 

Funny, I've always noticed that when I've gone to the store on my bike.

From the site... with wind speeds of 150 km/hr...

That's only 80knts.

That's relatively mild. When it gets up over 120 knts that's when the cameras come out.
 
Given the location that's more the subtropical jet stream than the polar stream. Polar ones tend to be faster (and a bit lower altitude).
 

That's only at the locatio of the velocity shown, not in the 'red' area... the red area is 150km/hr or faster...

or like the attached. 268 km/hr... This is at 12,000m... at 9000m, the speeds are quite a bit lower.

Every airline has a department dealing with this stuff and optimisation of flight routes.

It's a bit of a dark art. The weather guessers quite often get it wrong. And some of the flight planners seem to have a third sense which direction to send you.
 
Looking back up this thread I am seeing some things that don't fit the news reports for the Ever Given grounding incident. News indicates a sudden gust hitting the ship from the side, and visibility issues due to a dust storm. But the ship was headed directly into the wind. Allstair_Heaton reported the captain of the Maersk Denver had enough visibility to see the situation developing ahead and stop his ship. And additional seconds to get in an argument with the Egyptian pilot before taking control. These ships don't stop on a dime. So the captain must have had good visibility, and hence the additional time, to avoid a collision.

Any comments?
 
The wind pictures here seems to all be from the forecast, so they are not actually showing the the correct winds when it happened.

it might not be visible to the eye.

These boats have multiple radars and transponders.

All the channel markers have radar reflectors on the top of them
 
You mean these ones?

That having an argument with the pilot thing still brings up the responsibility question. If the captain is always in charge then he shouldn't have had to "wrestle" control from the pilot. If the pilot was in charge on that ship and needed control taken away, then the pilot would have been in charge on the Ever Given which makes the crash their fault.
 
Its happens in all multi crew control situations with command.

We have the same thing multiple times a day while flying. Air traffic control, marshalling of aircraft on the ground, technicians and technical issues, operations etc.

The Captain has ultimate authority and responsibility but 99.9% of the time you follow what you have been requested to do. But occasionally you have to put your foot down and say NO. And then when someone try's to bully you then you assert your command.

Its a very personal skill set and to be honest you can't teach airline Captains to have this leader quality. There are also cultural differences come into play. It takes about 6-12 months for people to grow into the role. Some fail and unfortunately have to go back to being a follower.

I will admit 16 years ago now when I was doing my command course I had a pushy air traffic controller trying to push us into a situation which would have solved his problem with another aircraft but would have taken away my escape options. I refused he got stroppy and it was instinctive to shut him down and assert my command. That 5 seconds after you say something did make me pause but then you have the rest of the flight to complete. Debrief was short and sweet. Good call, nicely dealt with, he wasn't happy but tough you are the Captain I think we can sign the command responsibilities and asserting's them section off.

I am pretty certain its the same in maritime after doing crew swaps with supply boats for the Northsea. Some Captains were the micro managers and others were more relaxed but you knew if problems occurred there was one boss.

I suspect the bloke that told the pilot to sex and travel is similar to myself. Comes from northern latitude stock, started life in heavy industry with rough men to manage and has a instinctive reaction when his third sense alarm bell is triggered.

I also suspect similar to myself we are best kept away from the office admin staff and office politics because it really upsets things when our bull in a china shop method of conflict resolution comes into play. But such is life bosses are happy that the job gets done safely and economically, our crews are happy because they have a boss that doesn't take any shit and protects them.

I like nothing better after working a week down route when the most junior usually young lady onboard feels comfortable enough to tease me in the crew bus because say my uniform is showing a weeks worth of wear and I could do with a clean tie. "hey Alistair are you going to make soup with that tie when you get home?" I think it means that I have managed to promote communications in my team with even the most junior feeling they are empowered to speak to me. Which I believe is crucial for flight safety. I know some crew its only the number 1 cabin crew who speaks to the Captain. I would hate to work in that environment. In fact if it was normal in a company I would be looking for another job pretty quickly.

In case the above sounds a bit to aggressive, the skill I told new commanders was the most important was the ability to listen even if what you were listening to was bollocks. But there are times which are relatively rare when you have to shut the person speaking down and assert command.
 
It continues...

"An appeals chamber at Ismailia Economic Court held hearings on Saturday over the ship's detention, which the SCA is seeking to uphold following an appeal by the owner, as well as the SCA's financial claim.

Lawyers representing Shoei Kisen argued that the SCA had been at fault for allowing the ship to enter the waterway amid bad weather, Ahmed Abu Ali, a member of the legal team, told Reuters, adding that the authority failed to prove any fault by the ship.

Recordings from the ship that were presented to the court showed disagreements between SCA pilots and its control centre over whether it should enter the canal, Abu Ali said."
