I’ve started to add wind to Sitrec

Currently, it’s just the relative wind speed of the clouds.

This can be confusing.

I’m assuming the jet starts out going North (0°). The wind is reported as “120 knots from the West” – and I’m assuming that’s the local wind velocity – i.e. in the air mass that the jet is flying in. Now all the calculations are done relative to airspeed, and previously assumed everywhere the wind was the same. So it makes no difference to the relative position of things what the wind actually is. So it’s set to zero.

The jet is at 25 ... Read even more
