I know that the weather is nice today, I am saying that if the planes were running as normal the sky down here by now would be foggy and trailed.
Sorry, but that's crap.If the nice weather was caused by no planes, then how come it was forecast to be clear? Do you think weather models include plane movements?
There are still no planes, but now it's hazy with high level cloud where I am - how would your hypothesis deal with that?
I have seen perfectly clear days with planes flying overhead. Explain that.
The reason why the sky was clear yesterday was because we have a dominant high pressure system overhead, with no mixing of air.
The reason it is cloudy today is this:

(the occluded fronts spanning the country being the key).

1: The weather is nice. it was always going to be nice regardless of planes or no planes.
2: Down here in cornwall we get a lot of overhead air traffic.
3: the planes running (in the nice weather we are having anyway) normally leave trails in the sky that spread out and make the (already nice day) sort of cloudy.
4: I wanted to know why some leave trails and some dont, and If you read the thread and the questions and answers in it you would know that at no point did I say the lack of planes is why we have nice weather.
5: it is a bit hazy here today as well but it is clearing into a nice blue sky day again, a day the planes will not fog up and add to the haze already present.

When I lived in Perth, Oz the weather was obviously pretty good 10 months of the year - clear blue sky every day.
I did notice however that the sky was never as clear and crisp as when we have clear days in the UK (twice a year!) it was always a bit dirtier.
Perth is the most isolated city in the world and the amount of air traffic was minute compared to the UK so how do you explain the clear blue skys (in comparison) to the UK?
It's just a coincidence, and anyway it clouded over this afternoon in East Anglia.
Is it not possible that there is more dust/sand in the air in Australia than in the UK??I did notice however that the sky was never as clear and crisp as when we have clear days in the UK (twice a year!) it was always a bit dirtier.

Nothing to do with plane emissions or contrails.

2. Ok.
3. We'll assume this to be true for the purposes of argument.
4. If 3 is true, then yes, you did. You're saying that planes make it cloudy.
5. Oh look, you said it again! You're saying that the day wouldn't be getting "nice" as much if there were planes in the sky, that they would add to the haze.
Oh dear indeed.

No, I said the aircraft make trails that spread out in a clear sky, they do not make clouds or alter the weather.BMWBen said:

I have noticed that whan aircraft are operating normally the sky soon gets misted up with merging, drifting trails, Its not weather its aircraft induced foggy haze, its not even a thick covering its a sort of misty smeech.Yet not all aircraft operating in the sky at the same time leave lingering trails.
I prefer the sky minus the trails to be honest, I am not a f
king hippy, I dont believe in mmgw I just prefer blue skies, I understand its not going to last forever and I am sure I will be flying in the same sky contributing to the problem soon.Getragdogleg said:

Global dimming is a factor, and was measured in central USA after 911. I don't know the amount of dimming the 'planes cause but it was measureable, very very small but measureable.
Free air miles to you sir for your attention to grammar.
