Your post showed that cirrus sometimes come ahead of weather systems and that areas where clouds have formed may give a glimpse of the rare effect called a persistent contrail. This is not new. Even wiki knows this.

You still fail to understand that it is not humidity, but relative humidity that determines whether contrails form or not.
Perhaps you could show a textbook reference or something that says there's more humidity the higher you go. Rogue, ambient humidity hot spots are an interesting theory but a rather convenient one for you, don't you think?
Climatology of Upper-Tropospheric Relative Humidity from the Atmospheric Infrared Sounder and Implications for Climate
The observations illustrate many scales of variability in the atmosphere from the seasonal overturning Hadley–Walker circulation to high-frequency transient variability associated with baroclinic storms with high vertical resolution. The Asian monsoon circulation has a strong impact on upper-tropospheric humidity, with large humidity gradients to the west of the monsoon. The vertical structure of humidity is generally bimodal, with high humidity in the upper and lower troposphere, and a dry middle troposphere.

My post was about the many billowing chemical trails in a cloudless sky that spread out into fake clouds. You have not addressed this.
Global radiative forcing from contrail cirrus
Contrail cirrus initially form behind cruising aircraft as line-shaped contrails and transform into cirrus-like clouds or cloud clusters in favourable meteorological conditions, occasionally covering large horizontal areas5, 6, 7. They have been tracked for up to 17 h in satellite observations
Contrail cirrus supporting areas in model and observations
Contrails form and persist dependent on the surrounding moisture, temperature and pressure fields and on fuel and aircraft specific variables. After formation, contrail persistence requires only supersaturation relative to ice.
Prevalence of ice-supersaturated regions in the upper troposphere
In situ measurements of water vapor and temperature from recent aircraft campaigns have provided evidence that the upper troposphere is frequently supersaturated with respect to ice.

you're going to have to sharpen up and understand the evidence posted in this thread instead of simply denying it is relevant when it obviously is
I saw the OP evidence and it was clear to me - is that what you mean?
It's great that you have come to accept this now.
I already posted balloon measurements from Nevada which showed that relative humidity can increase as you go higher in the atmosphere. It is not a theory, it is a well known and observed fact of the atmosphere.
The amount of water in the air can be measured in different ways. The specific humidity of air is a measure of how much water is in the air. Warmer air can hold more water than colder air. When the air reaches its capacity, it is saturated. This capacity doubles for about every 11°C rise in temperature. The term more often used is relative humidity. This is the measure of how much water is in the air divided by how much it can hold. The relative humidity reading is given as a percent. The relative humidity for saturated air is 100 percent.
I have already addressed how contrails can form in cloudless skies. If relative humidity levels are high in the upper troposhere, persistent contrails can form. Sometimes these conditions occur in cloudless skies, especially in regions that are supersaturated with respect to ice.
Contrails tend to last longer if there is higher moisture in the atmosphere and associated higher level clouds such as cirrus, cirrostratus and cirrocumulus already present before the plane flies through.
I mean looking at the evidence such as that above, instead of relying solely on a chemtrail sites misinformed "tips".

So by the time you get up really really high and really really cold, 60% doesn't mean the same thing that it meant at sea level as far as how humid is it really. In fact, it means vastly different things.

The same situations that form clouds would be the same situations that form persistent contrails. And yet observation doesn't show this. Clouds here are rare except for the fake clouds made by chemicals from jets. The fake clouds are common. The fake clouds form almost always in cloudless skies.
Ice supersaturation in the tropopause region
For ice crystal formation high ice supersaturation (i.e. relative humidities over ice larger then 100%) are needed; this is confirmed by many measurements (e.g. Koop et al., 2000; DeMott et al., 2003). Thus, the existence of cloud-free air masses in the status of ice supersaturation (so-called ice supersaturated regions, ISSRs) is clear from a theoretical point of view and it was also proven by a variety of measurement techniques.
You clearly have trouble with reading comprehension then. Let me quote what I have said.

Originally posted by Curious and Concerned
I then explained (with evidence) why humidity at ground level does not in any way preclude contrail formation, as relative humidity can vary as you go higher in the atmosphere.
Originally posted by Curious and Concerned
Humidity often decreases as you go higher, but as the ability for air to hold water vapour decreases, relative humidity can increase and often does.

You've told me that contrails form where clouds form. No clouds are forming.

You've told me to rely on the 'meteorologists' on ATS rather than chemtrail sites.

There was more sensible information in my previous little link on telling contrails from chemtrails than I've had from you.

Almost everything you've told me, including humidity levels, hasn't been a reflection of the actual situation.
Alpenhorn News
These doctors have said they are seeing larger numbers of patients with these complaints during or within days after the times that the physicians themselves have observed a larger number of chemtrails in the skies above mountain communities.
Ed Burrows, a pharmacist who lives in Crestline, told The Alpenhorn News that he is seeing similar signs of illness in himself. Since early December he has been suffering from a respiratory ailment that has includes a “gooey phlegm” that, despite his best efforts, he has been unable to relieve. Burrows said the issue is raising “high concern” for him that his health may be “jeopardized.” Burrows said he “feels that it is directly related” to recent chemtrail activity.
“Our government’s refusal to level with the people indicates that whatever it is they are polluting our environment with must be dangerous and/or unhealthy. There is no need to be secretive if what you are doing is beneficial,” he said.
4.1. Airplanes ....-
larger planes, such as the KC-135 Stratotanker or KC-10 Extender (Figure 2b), are capable of reaching the required altitude. ......
Clearly it is possible to design an autonomous specialized aircraft to loft sulfuric acid precursors into the lower stratosphere, but the current analysis focuses on existing aircraft.
Options for dispersing gases from planes include the addition of sulfur to the fuel, which would release the aerosol through the exhaust system of the plane, or the attachment of a nozzle to release the sulfur from its own tank within the plane, .......
The military has already manufactured more planes than would be required for this geoengineering scenario, potentially reducing the costs of this method. Since climate change is an important national security issue [Schwartz and Randall, 2003], the military could be directed to carry out this mission with existing aircraft at minimal additional cost. ...
Unlike the small jet fighter planes, the KC-135 and KC-10 are used to refuel planes mid-flight and already have a nozzle installed. In the tropics, one option might be for the tanker to fly to the upper troposphere, and then fighter planes would ferry the sulfur gas up into the stratosphere (Figure 2b). It may also be possible to have a tanker tow a glider with a hose to loft the exit nozzle into the stratosphere.
That contrails form can herald weather systems, since you claimed they do not. If you had said sometimes they do not you would have been correct, but you didn't.
I have pointed out numerous times that they are different things. Glad you are catching on.
Perhaps I should have explained what a region supersaturated with ice was. It is a region of more than 100% relative humidity with respect to ice. These regions often don't have clouds, but will be conducive to persistent contrail formation.
In contrast to water clouds where the saturated/supersaturated environment and the cloud are almost identical, for ice clouds there is a fundamental difference: For ice crystal formation high ice supersaturation (i.e. relative humidities over ice larger then 100%) are needed; this is confirmed by many measurements (e.g. Koop et al., 2000; DeMott et al., 2003). Thus, the existence of cloud-free air masses in the status of ice supersaturation (so-called ice supersaturated regions, ISSRs) is clear from a theoretical point of view and it was also proven by a variety of measurement techniques.
Persistent contrails often form in air with relative humidities with respect to ice (RHI) exceeding 100% but with relative humidities with respect to water (RH) less than 100%. Cirrus cloud formation generally requires RH > 100%. Thus, contrails can form clouds in conditions that would not support the formation of most natural cirrus.
This means contrails can form where there are no natural cloud formations.
I've provided you with information of high relevance, but you have either misunderstood or just ignored it when it doesn't fit in with your misguided theories on "fake clouds".
These planes were not in "formation" but they were flying one after another like you see on that video.

My description of how to maintain log books was clear......there are recognized alternate methods, and the company I worked for (the airline), their own records meet that qualification.
There are two Mods here at ATS that also once worked for the same airline as I, and can vouch for my veracity, as I have been in contact with them, long ago.
The entire ATS staff are aware of my past, and can vouch for my authenticity too.
Shoot them a U2U.......go ahead, make my day!!!

E-PEACE (Eastern Pacific Emitted Aerosol-Cloud Experiment 2011 ).
... a technique for dispensing GCCN (milled salt particles) in marine stratocumulus clouds and then measuring the response of the cloud to the seeding was developed and tested.
The Twin Otter was equipped with an extensive suite of instrumentation for characterizing clouds and aerosols and measuring meteorology parameters and turbulence. A 95 GHz Doppler cloud radar was operated in an upward facing configuration to measure cloud and precipitation structures observed above the aircraft and served as an effective tool for detecting a broadening of the cloud droplet spectrum and drizzle production due to seeding. The salt powder consists of salt milled to 3-5 micron particles that are coated to minimize clumping. The particles were dispensed from the Twin Otter using an apparatus that uses a variable-speed auger feed to deliver salt from a reservoir into a fluidized bed of sand (to breakup any particle clusters) and then blow the particles into the airstream from a tube extending from the underside of the aircraft fuselage. ams.confex.com...
The Eastern-Pacific Emitted Aerosol Cloud Experiment (E-PEACE) uses satellite and in situ ship- and airplane-based measurements of anthropogenic aerosol in stratocumulus off the coast of Monterey, Calif., to shed light on cloud-property modification by aerosol. One novel aspect of the experiment is the controlled release of aerosol particles. These order 100 nm-diameter particles are produced on board a ship at a rate of 10^15 s^-1 and greater along pre-selected ship tracks to raise aerosol concentration above marine background levels over areas of hundreds of km^2 in area. Production of the aerosol patterns is timed to permit study by instrumented aircraft and the morning and afternoon Earth Observing System (EOS) satellite constellations. We describe the particle release patterns employed in the E-PEACE 2011 campaign and the cloud structures into which the particles were released, and we present results from the study of these tracks and other ship tracks using EOS satellite cloud and aerosol observations. ams.confex.com...
