Discontinuity in the weather

Everything related to weather simulation, visuals should be discussed in the shader subforum.

I've identified the file and relevant functions here such that you can look into the code yourself if you believe something is wrong - given that you improve the Concorde, you appear to be quite able to deal with Nasal code, so you can just hop in, follow what the routines do and go looking for bugs.

I've never seen discontinuities in my tests - doesn't mean they're not there, they can have been accidentially introduced, or be triggered by something exotic, but I plainly don't have the time to go looking myself whether I manage to trigger the same situation.

could these discontinuities be related to the load on the system and how long updates take at different times?

would having a (eg) list of METARs from say 10 airports within a 50nm range and averaging them at the "border" with each other work to prevent these rapid changes? maybe more than 10 would be needed? possibly could eliminate some that have identical weather?
"You get more air close to the ground," said Angalo. "I read that in a book. You get lots of air low down, and not much when you go up."
"Why not?" said Gurder.
"Dunno. It's frightened of heights, I guess."

I've tested continuity of parameters rather extensively when writing AW and I've never seen the wind jump if the chosen wind model didn't have jumps - so I can't really comment what causes the things I've never seen...
