contrails (chemtrails)

[IT Minion]

Where did you get this information? I looked online, the difference will stay constant. Can you give me a link where it says the difference between atmospheric pressure and temperatures at similar heights will differ ?

Define similar heights. I was saying that they can be different at the same height on different days even if the weather at ground level is similar. The troposphere loses 6.5 degrees per km (~3,300 ft) so a 500 foot difference in height means a degree difference in temperature.

Have a read about the various atmospheric levels and boundary layers. The Tropopause changes height based on high altitude weather systems and that determines the cruising altitude of planes as they want to avoid the turbulence around the boundary between the troposphere and stratosphere. In fluid dynamics any boundary layer is almost by definition turbulent, chaotic and inconsistent.

Today everyone look up. You are seeing normal clouds right now the whole of England there are no chemtrails, this is a normal day. Look and remember and I will tell you when it's a chemtrails day.

I’m not sure whether you are just trolling or you really are that gullible.

Pretty sure it’s trolling.

If it is 20 deg centigrade at ground level, at 40000ft it will be about -6 deg c for every 1000ft higher. If atmospheric pressure is 1 atmosphere at ground level, it will be considerably less (0.19 atm) at 40000ft. This is physics, the same conditions on 2 days will have the same figures. Wind speed may change slightly, but all that would do is disperse the trails quicker if they were water vapour, but you would still see them.

No, that's overly simplistic physics from someone who hasn't ever done cursory reading about atmospheric levels. It is much much more complicated than that.

Air pressure isn't the primary factor, temperature and humidity are the biggest factors. Air pressure is effectively cancelled out as planes change their flying altitude based on the actual pressure variations.

Wind speed may change slightly,

This is also really wrong, have a look at a Jetstream map, that can be 100mph or more difference in speeds, today the Jetstream is moving over the country north to south so a huge range in wind speed.

There were contrails yesterday, but none today.


It kept drizzling and raining, on and off, yesterday.
It has been dry all day today, and is forecast to remain so.

Its amazing, the same people who deny climate change because the weather is always changing insist the atmosphere is so static that the temperature at 33,000 feet can't vary at all day to day or a kilometre higher.

So explain today the conditions are exactly the same all over England, all day, conditions that you try and tell us are the reason for hoz to hoz, stay into the air for hours on end spread and join.
You can not say one plane does it and another not at that same height and so on, because of varying conditions and then also try and say that today with no chemtrails all day anywhere in England is because there are no varying conditions -- seriously all over the whole of England.
And if it were down to varying conditions why do we not see the on/off nature of chemtrails from a plane as it passes through them.
And none at night.
I put it to you there are none at night because there is no sun to cover up.

There never are any geoengineers (chemtrails) working on Sundays, nor bank holidays. They only work a 5 day week.

anyone with due diligence can look up at the sky and tell if it is a clowd day or a chemtail day. it is not that hard to spot; unless you are an Orwellian 2+2=5 moron that is

They aren't.

Actually you can, although it's not common. Different models and eras of Jet engines are more or less prone to create contrails because of the temperature of their exhaust. For example all engines are more likely to produce contrails when they are working harder so planes gaining altitude might generate a contrail when a neighbour that is cruising or coming in to land won't.

Its almost as if this stuff isn't as simple as you think it is.

The spelling mistakes are a bit too much. Tone it down a bit and your troll account will last longer.
