Yessir!
Those are cirrus clouds. I see four recent contrails, the curved one is normal when a jet makes a turn enroute. remember, the jet is moving at seven
to eight miles per minute. In a gradual turn, usually at altitude, we use about 15 degrees of bank. That makes for a very large radius turn, several
miles in radius actually.
You can google "turn rate calculator" to see a program that you can plug numbers into.
The other clouds? Could be a result of older contrails, that due to conditions, just grew and stayed as cirrus. You see, because of whatever is
happening up above, temperature and humidity wise, you were going to have cirrus one way or the other. Contrails just move that along.
Did it rain the next day? Or, was it different? Cloudier all day? Overnight?
See, that's weather. It changes. Been doing it since before airplanes were invented.
I saw a book, the other day....it could be helpful. It's part of the "
Complete Idiot's Guide" series....there is one on the weather.
(I just picked up the one on Physics, just to brush up.....)
