On aircraft which fly above 30,000 feet, the temperature can often can get to temperatures below Jet-A's freezing point. For example: at 36,000 feet the standard outside air temperature is -56.5°C (-69.7°F) and is well below Jet-A's freezing point of -40°C/F.Mar 12, 2014
As the pressure gets lower, the temperature decreases. The rate of decrease of temperature with elevation is known as the adiabatic lapse rate, which is approximately 9.8 °C per kilometer (or 5.4 °F per 1000 feet) of altitude.

I'm not smart enough with weather physics to figure out if at 30,000 feet with 32°F, and if ground temperature is 57°F, what would the temperature be at 30,000 feet. I may be smart enough but just lazy. Does anyone with more brains than me know how to answer this?

. I don't remember any Chemtrails until around the year 1998-99
and thats all i need to read
“Let’s ask ourselves….Why did I see 75 planes spraying white stuff into the sky on my 15 minute drive to work? Who pays for this and why is it happening? Is something being exterminated here? Is that something me? Does this have anything to do with why Honey Bee’s are Dying off really fast. Why are some days normal with no planes spraying and others look like this? Whos is responcible? What effect will this have on our health and our childrens future? WHO THE F#*% THOUGHT THIS WAS A GOOD IDEA? Am I the only one who sees this? [sic]”

how are you able to differentiate between contrails and chemtrails? And more importantly, where did you learn what constitutes a chemtrail?

Anyway, the reason for this thread is last Tuesday, I went outside in the morning and there were no Chemtrails anywhere in the sky. I was thinking, "today is going to be hot day since there are no Chemtrails." It was 57 degrees and really warm!
List of temperatures for December in New Jersey:
www.accuweather.com...
You could argue because it was warm is why all the "contrails" evaporated. That may be the case. As I said, it's hard to prove one way or the other.
On aircraft which fly above 30,000 feet, the temperature can often can get to temperatures below Jet-A's freezing point. For example: at 36,000 feet the standard outside air temperature is -56.5°C (-69.7°F) and is well below Jet-A's freezing point of -40°C/F.Mar 12, 2014
And:
As the pressure gets lower, the temperature decreases. The rate of decrease of temperature with elevation is known as the adiabatic lapse rate, which is approximately 9.8 °C per kilometer (or 5.4 °F per 1000 feet) of altitude.
I'm not smart enough with weather physics to figure out if at 30,000 feet with 32°F, and if ground temperature is 57°F, what would the temperature be at 30,000 feet. I may be smart enough but just lazy. Does anyone with more brains than me know how to answer this?

So why do contrails spread out across the sky to create cloud cover? Does the contrail start a chain reaction? Why don't they dissipate? What prolongs their appearance? Why isn't it raining in California? Why are there real time images of precipitation clouds running into an atmospheric "wall" offshore of coastal California and literally being vaporized?
Water vapors were not common.
