NOAA wind direction when no wind reported

Post by RayProudfoot »

Steve,

On Thursday and Friday my anemometer was broken as you know. On my NOAA report it showed the wind direction from the East. Any idea why? I would have expected it to report North as I have that option set in Cumulus when wind is calm.

Yes, it should put 'dashes', but it doesn't; I can reproduce that here as my test stations have no wind sensor. It will take me a while to work out why it's not working as the Delphi debugger is broken (one of the reasons I'm moving away from Delphi) so I can't step through the code.

It's actually the code which calculates the dominant direction and stores it in dayfile.txt (which is where the NOAA report gets it from). I'll investigate when I can.

If you use the dayfile editor to change the dominant wind direction for those two days from 90 to zero, then the NOAA report will show dashes.
