A Question About Contrails

Sat Oct 14, 2000 11:02 am

I have noticed for several years, that is seems contrails appear more over St. Louis (my home), much more in the fall than in the spring or summer. Why would this be? Different weather patterns, or different flight directions? I would hardly see any in the spring or summer, but now there are contrails everywhere!

Well, one of the factors that determine size of contrails is the moisture content of the air up there. More moisture will allow for a larger contrail. Why there would be more moisture in the fall than in the spring, over St. Louis, I don't know.

Here in Ibiza (Spain) we have very few contrails in the summer time, but in the winter we have a lot.
I agree with Hmmmm... that moisture is the most important factor, another one might be temperature.
