ESTABLISHED
I can’t reply on drewswebsite because he has BLOCKED me. He’s the seventieth site to do this so far.
There could be THREE OR MORE transparent layers of air of DIFFERENT HUMIDITIES, only ONE of which condenses a “VAPOR TRAIL”, within the short-haul civil aircraft band between 30 and 35 thousand feet. Layer thicknesses of differing humidities are frequently only hundreds of feet thick and ARE CONSTANTLY VARIABLE in speed, direction, temperature and humidity. Aircraft are spaced ten miles apart on the same level for a particular route, and conflicting routes are nowadays 1000ft above or below each other.
So you’ll see SOME planes laying vapor trails while others don’t – it depends WHICH transparent stratospheric layer a particular plane is flying through.
Jet exhausts are NITROGEN, STEAM, and CARBON DIOXIDE at 2000 deg C (with traces of NOX and SOX). This cools RAPIDLY in an ambient stratospheric air temp of between -40 and -80 deg C to a FINE “WHITE SMOKE” OF ICE CRYSTALS in N2 and CO2.
If the stratospheric layer it is in is SUPERSATURATED (more than 100% humid), the ice crystals accrete more ice, get heavier, and fall faster.
If the stratospheric layer it is in is SATURATED (exactly 100% humid), the ice crystals REMAIN, but SLOWLY DIFFUSE TO FILL the stratolayer. The powerful WAVE VORTEX generated by the aircraft wing continues for tens of minutes after the aircraft has passed by, slowing to a stop very slowly.
If the stratospheric layer it is in is BELOW SATURATED (less than 100% humid), the ice crystals will slowly SUBLIME back into vapor AND THE TRAIL WILL DISAPPEAR.
The layers themselves aren’t perfectly flat – they roughly conform to the ground profile AND any rising CUMULUS clouds. So even if the plane flies straight and level, it may be the layer it is in slopes gently down or up, and THE CONTRAIL EITHER APPEARS OR DISAPPEARS as it enters a NEW stratospheric layer with a DIFFERENT HUMIDITY. You have to remember these layers, though different, are ALWAYS themselves transparent.
So you can’t SEE them. You can only see which layer is really humid by a plane throwing a vapour trail in it. Typically stratospheric layers begin ABOVE the TROPOPAUSE, which is where our ground level weather STOPS. It is NOT POSSIBLE TO PREDICT FROM TABLES STRATOSPHERIC LAYER TEMPERATURES FROM GROUND LEVEL TEMPERATURES.
The stratospheric layers vary in thickness, more densely packed close to the TROPOPAUSE, thinning out to nothing much above twelve miles up. It’s very smooth and calm up there – the layers slide over each other WITHOUT MIXING. Layers with HIGH GROUND SPEEDS are called JET STREAMS.
If there are MORE vapor trails in the sky than there used to be, then the answer is that there is MORE AVIATION TRAFFIC and MORE WATER IN THE ATMOSPHERE.
At this point someone will interject “Your Theory…” and I want to plainly cut this short.
THIS IS ESTABLISHED ATMOSPHERIC PHYSICS and NOT MY THEORY.
If you wanted to PASS ANY EXAMINATION IN THIS FIELD then you HAVE TO UNDERSTAND THIS TO BE THE TRUTH.
EURODELE
Eurodele, at least you are TRYING to ask questions, but:
“why many jets, laying persistent contrails, would converge in time and space 100 miles from any large airport” – Easy. The speed of stratospheric layers over your head can reach 100mph. If contrails are persistent, then they could have been laid just an hour previously “over” an airport. Next time you see this phenomenon, time the movement of trails from horizon to horizon, and estimate the speed of the stratosphere
“strangely concentrated and patterned jet trails through or over which other jets can pass with normal contrail dissipation” – From FIVE miles beneath, you CANNOT TELL between “through” and “over”. This makes ALL THE DIFFERENCE if one (invisible!) layer is HUMID, and the layer above or below it (also invisible!) is DRY. Contrailscience cannot be held responsible for your failure to INTERPOLATE information…
EVER
Look, Ever, I am a normal guy looking at PURE BUNK: this last statement of yours. The proof that this last statement of yours is HORSE FEATHERS can be found by any sensible person merely by going to their LIBRARY, and READING any book they like which covers ATMOSPHERIC PHYSICS. Now you wouldn’t object to that, would you?
“I’m one of the many victims” – of an industrial economy.
“They are spraying” – IT IS MAKING AUTO FUMES, PHOTOCHEMICAL SMOG, AND INDUSTRIAL POLLUTANTS.
“I will not go out to see them because my asthma is terrible” – ASTHMA IS CAUSED BY THE ABOVE AND ALSO BY POLLEN.
“Whatever these things are” – I thought you KNEW
“they are indeed making people sick” – People have been made ill by industry for 150 years in your country.
“The quality of the air is so poor in the Bronx and lately it is worst than ever” – Your country is producing effluents at an ever-increasing rate
“I wonder why” – NO YOU DON’T. You have already come to a WRONG CONCLUSION.
“Debunkers/ experts/ authorities on/ chemtrails/80-90%/ real info/hidden propaganda” – Why did you write this and why the quotes? What hidden propaganda? There’s NOTHING hidden here – check my channel – I’m a MUSICIAN here.
“If you are a Musician, why do you get so defensive about this topic? I see that you spent a lot of time proving your point, great.” – I am defending (quite literally) – nothing. I am ATTACKING false and dangerous beliefs.
The Bard of Ely (with whom I have worked) enjoined me to support his “chemtrail” blog. When I read it I was astonished – I’d never met such rubbish in my life. I knew FROM EXPERIENCE (I’m an ex-aeronautical engineer) that the whole idea was wrong for a HOST of reasons. I thought that a small campaign of scientific advice would clear it up – more fool me! There have been 60 Google pages listing my attempts.
My main concern is with HEALING. If one suffers from the delusion that aircraft are deliberately spraying you with substances to make you ill, and you ARE living in polluted air, then any illness you get merely serves to CONFIRM your delusion. If, however, I manage to convince a person such as YOU, suffering from such a delusion, that after all, aircraft are NOT spraying you, you may PERMIT yourself recovery from what was a temporary state of illness. You also have a choice: to MOVE to cleaner air, or to AGITATE to remove the sources of pollution.
There is a third and most important point, that almost NO-ONE has any confidence in our system. This is because PAST APATHY has allowed the wrong people in. The ONLY WAY to get the government you want is to BE the government you want. Frank Zappa was right: you MUST stand for office.
The very best outcome of this “chemtrail” movement would be a NEW PARTY – neither Republican nor Democrat – which would seek to redress ALL the terrible imbalances to Nature that we have created, whilst preventing both a cultural CRASH, and a Global Warming CRISIS.
But you’ll never do it without a full understanding of SCIENCE…
EVERYTHING
New Developments of the Theory of Everything
(Nothing whatsoever to do with “chemtrails”, but I don’t care!)
Startling progress has been made towards a final physical theory of Everything (sometimes called TOE) which unifies and brings into comparison the disparate Theories of Relativity and Quantum Fields.
If true, the gaps in our knowledge will be displayed. That which we don’t know that we don’t know – we will know!

EVIL
“serve to cause confusion to the issue” – That seems to be YOUR role here as it is QUITE OBVIOUS that what comes out of a gas turbine IS what makes SODA-POP.
“attempt to make rational people who are making observations and discussing their experiences appear to be conspiracy nuts and/or uneducated” – ANY “rational” person would know to read up on technical aspects BEFORE “making observations and discussing their experiences” especially if they felt they were uninformed.
“You are using faulty logic and classic emotion based redirection (example “This rising panic ensues from an under-educated public”) as the basis of your argument” – the public IS under-educated. YOU are under-educated. YOU are KNOWINGLY using faulty logic and classic emotion based redirection when confronted with my challenge that you ARE under-educated (see the subject of EVIL below).
“These are exactly the tactics that are used to manipulate rather than uncover the truth” – for you this statement ISN’T a discovery!
“You should know that your posts are smacking of someone with an agenda” – and yours positively REEKS of one.
“government plant” – AHA! We’re sophisticated these days at http://www.myspace.com/jazzroc – hope you like the blog, piccies and music.
“No one mentioned anything about what the trails were” – DISINGENUOUS hypocrite! I quote – “Obvious trails, definitely converging” – “latest plane curving at same angle” – “they just keep coming” – “it’s pretty obvious” – “that’s the one” – “somebodies doing something” – “really strange spiralling effect” – “they’re just non-stop”. My, my, how “INNOCENT” you really are….
“YOU were the one to put forward a theory for what they are” – It is THE EXPLANATION made from an understanding of atmospheric physics. It isn’t a “theory”. It is established atmospheric science. Your “chemtrails” are a theory.
“YOU said the video post is “wrong” which makes no sense – my video was only making an observation that something is going on” – OF COURSE it is wrong. If I hadn’t typed in “CHEMTRAILS” I wouldn’t have pulled you up. That very WORD is a LIE with no basis.
“In additional YOU brought up the subject of evil, no one else here did” – IT IS EVIL TO KNOWINGLY MISDIRECT AND TERRORIZE OTHERS.
EXHAUST
The stratosphere temperature at the tropopause NEVER RISES ABOVE -40 deg C.
In A FRACTION OF A SECOND the exhaust, a mixture of NITROGEN, STEAM, AND CARBON DIOXIDE cools down from 2000 deg C to -40 deg to form a WHITE SMOKE OF FINE ICE CRYSTALS in a column of N2 and CO2 gases.
In HIGH HUMIDITIES that trail will PERSIST and even GROW. In LOW HUMIDITIES the ICE will SUBLIME to invisible WATER VAPOR.
EXPONENTIAL TIMES
There is no-one alive that can possibly be sufficiently clued-up on this. Whether you’re a specialist or a generalist makes no difference – from now on some aspect of our developing world is going to take you completely by surprise.
There is no doubt that one day soon an off-the-shelf computer will possess a greater processing power than the Human Brain.
But in the interim we will all have created (and endured) a startingly-exponential rate of change which could easily be totally out of our control. In the generation after the next we might well have produced a computer powerful enough to help us regain control of our civilization, but in the meantime – we’ll just have to rough it.
EXTREME?
Extreme? I find myself arguing with people who know the extremes of NOTHING. They’re hardly capable of anything. They know the extents of their boundaries, and kinda suppose that the rest of the world goes on just a bit longer…
Chemtrailers are like people who are hammering their hands with hammers and complaining about the pain. They know no extremes other than their own extremities.
Extreme?
THIS IS EXTREME!

FORTRESSES
“other planes left Con trails that vanished” – then the trails were left in a DRY layer.
“other planes did not have trail” – they ALWAYS leave a trail in the stratosphere, but it may be VERY SHORT.
“at various heights” – ABOVE FIVE MILES?
“other trails lingered, spread” – then the trails were left in a SATURATED layer.
“are these trails Chem or Con trails” – CONTRAILS.
“I don’t know, I’m not a bird or a scientist” – I DO know. I AM a scientist.
“length/linger/sheet/layer/haze/slide/spray pattern/within 5-10 minutes/suspicious” – just coincident with a WET layer of the stratosphere.
“not natural/condensation trails” – you’re not a bird or a scientist, remember?
“know that planes dump fuel/not sure they dump it this low” – a plane that dumps fuel is doing it in order to survive an immediate landing. Being mobile it normally goes out to sea to do it, and will be LOW DOWN. Your chances of seeing THAT are RARE indeed.
“don’t know if it is fuel or something else/fuel = chemical” – EVERYTHING is a chemical, unless it is an ELEMENT. You’re not a bird or a scientist, remember?
“This is not the first time” – that aircraft have left persistent contrails in saturated air? Flying Fortresses in 1943 certainly did!
FRACTALS IN NATURE
Fractal calculations have an ever-expanding relevance to the task of understanding Nature with the tools of Science.
FROZEMAN
first of all, the theme by thomas tallis is very good and the pictures too, i am from germany, so my english is a little bit poor.
it seems to me that you have a good knowledge about atmospheric procedures, so i want to ask you a question.
i have watched “chemtrails” for over 2 years now, and i am still not clear, if it’s chemical spraying or normal contrails.
i understand the “layers of differing humidities” principle, that can explain some “chemtrails”. so that i see here a “chemtrail” and there a normal contrail. ok but i have filmed airplanes that have no contrail at all, and beginning to spray, and make an longstanding contrail and then stop it, to make no contrail again.
the confusing thing here is for me is that this airplane made a wingwidth stripe almost direct behind the plane. so you dont’ see two or four stripes, or how much engines it had, you see only a thick stripe all over the wingspan and it stays for hours and diffuses to thick cloud, and before it had no contrail and after that, and it sprayed at the end some little short trails, as if it stop the spraying, and there nor come a little bit of it. you can literaly see how it sprays. and in the spray direct behind the plane there were colours in the trail, because of the angle to the sun.
what do you think of that, how is it possible, if an airplane had two or four engines that it can make such a trail, and then the trail stays for “ever”? thanks for your time, and sorry for my english. i am waiting for your answer.
Hi FROZEMAN – I appreciate your English, and how hard it is to write in a different language… I’m glad you liked my music video. It makes the hard work (and a lot of musical pleasure) even more worthwhile.
The plane was NOT “spraying”. “Chemtrails” don’t exist. It is ONLY contrails that exist. The phenomenon you describe is the trail of ice crystals left by an ordinary passenger jet flying through a supersaturated stratosphere. *The separate engine trails become “bound up” in the wave vortex of each wing – these may be more than fifty metres across.
Read my blog at http://jazzroc.wordpress.com, especially SCIENCE ON TRAILS. It is towards the end of the alphabetically-sorted compendium.
There, a scientist describes carefully how and why the whole body of an airplane generates a trail in a supersaturated stratosphere.
“Saturation” is a term used to describe how the air is “full” to its limit with water vapor. Ice cannot sublime into the air, and so cannot “disappear”. Trails laid in such conditions persist indefinitely.
“Supersaturation” occurs in calm clean “laminar” conditions, where the air becomes “over its limit” with water vapor, and just needs the slightest disturbance to precipitate out its overload of ice. Trails laid in such conditions get LARGER and HEAVIER and FALL….
The ICE crystals in the trail generated by the wings and body are microscopic in size and can REFRACT and DISPERSE light by INTERFERENCE, which accounts for the colors one can sometimes see.
Ordinary cirrus clouds also produce (on occasion) such coloured effects. They are called PEARLESCENT CIRRUS. There is another name for them – NACREOUS CLOUDS.
There used to be stories of a pot of gold to be found at the foot of every rainbow. Now science shows that everyone sees a different rainbow, and there is NO WAY you can approach its foot – ever.
“Chemtrails” are like this; a myth which, like a rainbow, disappears as soon as science looks at it. Let it go…
