Happy SUNday! – sky trails and sky snakes.

Chris and Carol Leave a comment
Two jets at different flight levels along the same high-altitude jet route over Amelia Island.

What’s fascinating about these two jets’ contrails is that the higher jet’s trail lasts just a bit longer, as at that level (probably at 35k), the air was more favorable for the condesation trail, so it persisted longer than the lower jet (probably at 30k).

The jet route from South Florida that runs northward along the East Coast of the U.S. crosses over Amelia Island. The atmosphere was favorable for the formation of contrails on this day.

As a U.S. Navy meteorologist, I was often tasked to forecast the formation of condensation trails, as they play an important role in operations. As an observer, I called them sky snakes.

Just a few minutes before the top pictures depicting different aircraft.
