It is Time for Professional Meteorologists to Step Up & Begin Forecasting the Big White Elephant in the Sky

Over the last last 4 months I have attempted to forecast contrail events for Central Wisconsin. Untrained in meteorology and particularly in upper atmospheric science, I have had to rely on ground based observations of weather and air traffic patterns and national weather maps and local weather forecasts.  Here are a few things I have learned or observed:

1. All combustion aircraft leave a persistent trail, invisible from the ground, called an aerosol trail, aerotrail for short.
2. The aerotrails are composed of cloud condensation nuclei. (CCN) These are basically small particles of soot that may form into water droplets or ice crystals depending on the temperature of the air.
3. All combustion aircraft add water vapor to the atmosphere.
4. The lengthening or shortening of contrails (cirrus aviaticus) indicates areas of temperature or moisture changes in the upper atmosphere or both.
5. When contrails of short duration begin to lengthen, going to needle size, to pencil, to fishing pole, expect persistent contrails to begin forming. 
6. As drier or warmer upper air masses move into flyway areas expect to see the contrails become shorter in length and duration or not appear altogether.
7. When natural cirrus clouds move through a flyway, contrails will more likely be visible.
8. Multiple persistent trails may spread to form milky sheet clouds. I call these clouds cirrostratus aviaticus.
9. Persistent contrails most likely form on either side of moisture boundary lines, sometimes called dry lines. These boundary lines can be wide and I call them boundary sheets.
10. As the boundary sheets drift within the flyway additional aircraft pass though them laying more invisible aerotrails and moisture making the cirrostratus aviaticus denser in appearance.
11. If the drift is in the direction of the predominant flyway traffic the ice crystal saturation can lead to the viewing of or at least enhance sun dog halos.
12. If  the persistent cirrus aviaticus (contrails) or cirrostratus aviaticus (milky sheets) drift outside the flyway, they tend to thin or dissipate.  With the lack of traffic no more man-made nuclei is added.
13. So far, from identifying the aircraft using flight tracking software,  I have not been able to identity any deliberate laying of chemtrails (chemical trails)
14. All the phenomenon I have observed so far has been from regular commercial airline traffic flying between 30,000-40,000'.

Today we have heavy persistent cirrus aviaticus clouds forming and morphing into cirrostratus aviaticus within the Central Wisconsin Flyway.
