CHEMTRAILS%20-%20CONFIRMED%20-%202010%20by%20William%20Thomas

When the flight data for an aircraft transiting an area matched atmospheric requirements for contrail
formation, the computer made predictions concerning contrail formation and persistence over CONUS.
Minnis, an ardent foe of “chemtrail conspiratorialists ”helped calculate the computer algorithms used to
estimate “CONUS contrail frequency”.
WHERE HAVE ALL THE CONTRAILS GONE?
“According to the classical contrail formation theory, contrails can persist when the ambient air is supersaturated,”
says this latest NASA contrail study, which isn’t often. Even when NASA’s meteorological
model was deliberately skewed with software modifications to predict more contrails under less than
ideal contrail conditions – the number of contrails was found to be declining.
The “Potential Persistent Contrail Frequency” shows the month of Thanksgiving to be typically the
heaviest air traffic month in the U.S. – where the region with the highest potential occurrence of contrails
continues to be the Pacific Northwest. Other regions of high contrail frequency occurred in central
Canada and the eastern Midwestern U.S. These areas can see twice the number of contrails as the
continental average.
But in December 2001 the distribution and magnitude of potential contrails “changed dramatically” said
NASA – not because of September 11, but as a result of radical, unexpected changes in weather
patterns between November and December.
Even in the contrail-congested Portland and Seattle regions, contrail frequency dropped well below
continental averages. Presented to the “10 th Conference on Aviation, Range, and Aerospace
Meteorology” in heavily chemtrailed Portland, Oregon in May 2002, NASA’s newest findings showed
that contrail coverage over the North Atlantic and central Europe remained “significantly smaller than
those given” in 1994.
Ditto the Pacific Northwest.
Yet the skies in these regions were more obscured than ever!
