wind vector - explanation regarding orientation (north to the right)

[samtheduck]

Would someone kindly explain to me (or point me to a published explanation) as to why, in the graphical presentation of wind vectors, north is to the right, rather than up?

If orientation is a matter of preference, rather than of global standard, is there provision in weewx for changing the orientation?

Did you check the Customizing Guide?

Hi Tom -

Old thread, but same question. I just upgraded to 4.5.1 earlier this week. I finally thot about fixing the compass rose orientation since my prevailings are from the south. I edited skin.conf where I found the canned 90 deg due to your prevailings. However, it doesn't take, and if I reboot weewx, it goes back and takes an hour to rebuild the database. What am I mis-doing?

I just tried setting vector_rotate to zero in Seasons/skin.conf and it worked fine.

Did you delete the old plots? Plots only get generated if there is no aggregation, or if more time than the aggregation interval has passed. So, the year plots may get regenerated only once a day. Deleting them all ensures that they will all get regenerated.

Not sure why you upgraded to V4.5.1. It's over 2 years old. V4.10.2 is the current version.
