Hello,

the zambretti forecaster would be create by pressure, pressuretrend an wind-direction.
My Problem is, that the wind direction in my region is very unsteady and so is the forecast very unsteady, too.
can I adjust the forecast so that the Avg-wind-direction is used, because the Avg-Wind-direction is more steady than the normal wind-direction?
where can I find these settings for cumulus-forecast?

Thank you for help.
Frank

It uses the average direction for the forecast calculation, it wouldn't really make sense to do it using the 'instantaneous' direction. If even your average direction varies so much that the forecast fluctuates, you could perhaps change the period over which Cumulus calculates the average, using the AvgBearingMinutes setting in Cumulus.ini or perhaps select 'update hourly' in the forecast settings on the station settings screen.
