Original Note:
If the air is supersaturated with respect to ice formation, the water vapour in the exhaust contrails turns immediately into ice particles, which can then become persistent. If the air is very dry, contrails do not form at all, or are of short duration. https://www.aerosociety.com/news/chemtrails-debunked/
