Posted: Sat May 19, 2007 12:35 am Post Subject: Asymmetry in Chemtrails Reported
Clifford Carnicom is arguably the most meticulous investigator of Chemtrails in the world. His scientific background and thus his adherance to 'scientific method', gives his site and his articles a degree of credibility that debunkers find impossible to counter.
The following article is an example of the type of research that is sorely needed in this country.
We ourselves have a certain degree of valid data derived from our own observations, and that will be published in due course. We however, 'suffer' from living in a part of New Zealand that, to this point does not present the type of operation that we have observed elsewhere in this country (and that others have reported).
What we require is backup, supporting material from others, with photographs together with meticulous annotations, accurately observed vectors etc. It's not enough to speculate about the odd persistent contrail and label it a Chemtrail...

Aerosol Asymmetry:
Core Tracks & Pulse Observations
Clifford E Carnicom
Santa Fe, NM
May 14 2007
A significant set of observations has taken place. On Mother's Day and the day following of 2007, another major aerosol operation was conducted over the skies of the Santa Fe, New Mexico region. A more detailed visual examination of some of these emissions has been made; mechanical, artificial and systematic introduction of the aerosols appears evident. There are two primary observed anomalies at this time: the first of these is the presence of what may be referred to as "core tracks" (ribbon-like; possibly filamentous in nature) and the second is the repeated presence of a characteristic "pulse" emission. The behavior and character of these anomalies is now being presented and an adequate basis for further examination exists with this article. These characteristics are completely out of accordance with any claims of meterological discontinuities in the atmosphere, any uniform fluid or gas dynamic analysis, and any unmodified combustive process. It is apparent that distributions of discrete material into the atmosphere are taking place. Complete Identification of these processes and the unusual chemical and physical reactions that accompany them are required to safeguard the welfare and interests of the citizens of this planet.

Core lines appear in this case on one wing side of the aircraft only.
These core tracks appear to provide a basis
for subsequent pulse pendule development.
Exposure taken a few seconds after the preceding photograph.
Notice the ribbon has become displaced, but has maintained its form;
this indicates a discrete substance from that of the trail.
A relationship to previously disclosed filaments should be considered.
It has been a question for some time as to why the "pendules" form as a regular component of the aerosol trails. It has been claimed by some that such pendules are just a normal development from customary meterological conditions. They have been referred to by certain parties as virga, which are defined as " wisps of precipitation streaming from a cloud but evaporating before reaching the ground1." Two objections can be immediately raised: first we are not dealing with "clouds" by definition (as clouds and conventional aircraft emissions are entirely different physical processes), and second, such a phenomenon would obey uniform laws of motion and not be commonly recorded in a repetitious or pulse formation. It is also clear that the aerosol materials are not immediately descending(as precipation is expected to), but that they are expanding and are part of an extended physical-chemical reaction outside any bounds of evaporation. In addition, such pendules will not be observed in combination with normal contrail formation, as evaporation, dissipation and rapid mixing of the heated water vapor into the air will dominate that process. It has also been clear for some time that an asymmetric process is involved in many of the aerosol formations, however, any clarification of that process has eluded most observers.
"Pulse" character of additional aerosol trail; May 14th, 2007, Santa Fe, NM
What follows is a progression of photographs that will demonstrate the further developments, transformations and reactions within an aerosol trail under examination. This progression occurs over approximately a 20 to 30 minute period. The time of this series is approximately 1015-1045. The initial sky conditions were generally clear and sunny, although it was apparent that an extensive aerosol operation had been previously conducted to the south. The result of the operation is that the sky became progressively occluded during the two day interval of this report. The majority of the occlusion was accomplished within the first few hours of the operation.

The core lines reported in this article have been observed at earlier times; they have been recorded during one scene of the documentary available through this site. The advantage of the current report is that clear images of the progression have been recorded. The process indicates a systematic distribution system that produces unusual and remarkable physical transformations in a relatively short period of time. The reaction is one of increasing, rather than decreasing intensity. It appears likely that ionization and dessicant qualities are significant catalysts in the reaction. The role of the core lines is not determined at this time, however, it appears quite possible that they are involved in the subsequent pulse and pendule formations. High quality imaging equipment is required to document the core tracks and they may be visible only under favorable lighting conditions. The possible relationship between the core tracks (ribbon-like in form and behavior) and the filamentous materials discussed extensively on this site must be considered. Any attempt to conceal the presence of the ribbon formations, past, present or future, should also be considered as a possibility. It is recommended that these observations be explored in greather depth so that the mechanics and materials of distribution and the physics of transformation can be more fully understood.

You can compare and contrast this paper with Dr. Carnicom's ideas. He's got one thing right though; that the wing tip vorticies affect the development of other structures in the contrail.
Back to this J.Atm.Sci paper: Note the publishing date; Feb 2001! The abstract is pretty dry, so I won't post it. The introduction describes what is going on far better than I could so I'll post most of it here. I have omitted some of the references and some other bits for brevity... it's still fairly long though, and well worth the read.

1. Introduction
Aircraft contrails have become a common cloud form, often representing the only visual perturbation in an otherwise cloudless region of sky. What is less readily apparent to the casual observer is that under some conditions contrails can grow, spread, and form what appears from the ground to be naturally occurring cirrus sheets representing significant cloud cover.
... we focus in this paper on one aspect of contrail development: whether the aircraft wake dynamics occurring from a few seconds to tens of minutes behind the aircraft can have any lasting effects on the resulting contrails.
In the evolution of an aircraft contrail, it is convenient to identify four overlapping regimes. During the first few seconds, the engine exhaust jets rapidly mix with ambient air and, for suitable atmospheric conditions, become supersaturated with respect to water and form a contrail. During the same period, the vorticity distribution shed from the wing rolls up into a pair of trailing vortices. The wake dynamics following this roll-up/jet regime are dominated by the interactions of the vortex pair. Typically in this stage the engine exhaust jets partly wrap into the vortex cores and partly detrain into a buoyant plume; the vortices fall and interact with each other through a mutual induction sinusoidal instability and with any ambient shear that is present, until they finally break up, typically within a few minutes. Given ambient conditions supersaturated with respect to ice, the contrail can grow as moist air mixes with the ice crystal rich exhaust plume. After vortex breakup, positive buoyancy acquired from the hot engine exhausts and from the vortex pair falling through any ambient stratification can dominate the dynamics until the plume mixes sufficiently with the ambient air, typically within one or two Brunt–Vaisala periods (10–20 min).
Finally, at later times, the plume dispersion is dominated by the interaction with the ambient atmosphere, via atmospheric turbulence, gravity waves, and shear. The latent heat release and radiative cooling within the contrail may also contribute significantly at this point as these effects are no longer dwarfed by the wake-induced dynamics. Under favorable conditions (particularly a large ambient supersaturation with respect to ice), the ice mass in the contrail can continue to grow and persist until the individual ice crystals become heavy enough to precipitate out.
In this paper we concentrate on the contrail evolution through the period following its initial formation until the wake motions induced by the aircraft downwash have decayed away — that is, from an age of a few seconds to tens of minutes. We employ large eddy simulations to study the full 3D unsteady wake dynamics in detail during this time period, including a bulk ice microphysics
parameterization for the contrail development. ...
The wake dynamics alone, ignoring the fate of the engine exhaust products, has also been a significant area for research because of potential effects on closely following aircraft and the resulting safety issues for takeoff and landing at airports. ...
Even a casual observer of contrails will have noticed the degree of organized structure often present as a young contrail evolves. Understanding this development is of interest for its own sake, and can provide information about upper-tropospheric conditions as well: the observed contrail development is sensitive to the local relative humidity, turbulence level, wind shear, and temperature stratification, for example. While this provides additional motivation for this work, our main concern here is with a potentially more important issue: whether this early dynamics has any lasting effect on the contrails that persist and grow for long enough time periods to potentially have a climatological impact.
There are already some indications from previous work that this might be the case. Studies of passive exhaust tracers (e.g., Lewellen and Lewellen 1996; Gerz et al. 1998) have demonstrated that the vertical extent and distribution of exhaust gases is largely determined by the type of aircraft and its wake vortex dynamics in the first few minutes; for quiet atmospheric conditions the vertical diffusion rate after this period is comparatively slow. Recent 2D case studies by Sussmann and Gierens (1999) have shown that the number of ice crystals present in the contrail can be significantly depleted in response to the wake vortex dynamics, at least for a heavy aircraft (B747) and ambient conditions only slightly supersaturated with respect to ice. We extend these results with our 3D simulations, allowing us to follow the full evolution of the wake even as the vortex pair interacts and decays. As we show below, the ice crystal number depletion can be significant even for smaller aircraft or for sizable supersaturation levels. There has also been a suggestion by Gierens and Strom (1998) that the motions in the aircraft wake may induce significant ice nucleation; we comment below on this possibility as well.
Ultimately, we would like to address questions such as the following. What are the most appropriate starting conditions for contrail studies after the decay of the aircraft wake? In assessing the impact of present and future global air traffic on the total cirrus cloud cover should one assume that the effects scale with the total fuel consumption, the total flight miles, or some more complicated combination involving aircraft type, emission inventories, and atmospheric conditions? Is there any obvious strategy for minimizing persistent contrail production? Our present results shed light on these questions, albeit without providing final definitive answers.
The paper is organized as follows. In section 2 ...
and so on ...
Here are some figures from the paper. These are computer simulations and guess what? These visualisations look just like what we see in the sky. They look remarkably like what Clifford Carnicom saw and photographed, but he puts a completely different construction on them... which he's entitled to, I suppose, and we can judge which is the better explanation.
The research into those forms and structures seen in contrails was completed and published over 6 years ago, and Carnicom didn't even bother to look for it.
One important thing that Carnicom doesn't comment on with regard to his study is the atmospheric conditions on those days. Was jet exhaust condensation possible or not? Well, guess what? It was! Here are the Contrail Analysis charts for Albuquerque at 6am and 6pm local time on those days. (Santa Fe, where Carnicom took his photos, is about 90 km northeast of Albuquerque.)
Apply the usual cautions and caveats for these analyses, but it's fairly obvious that he was looking at contrails from ordinary passenger or freight jet aircraft.
