Re: [weewx-user] Wind direction graph weirdness

The are 6 days in 2023 that are recognizable. Look at the daily/Weekly plots and how they look like. It should be possible to regenerate them, if you don't have any snapshots. For me, this looks like a classic upcast/valley wind graph. Tom Keffer schrieb am Dienstag, 12. Dezember 2023 um 00:25:

Re: [weewx-user] Wind direction graph weirdness

One thing I would suggest: make sure the wind direction vane on your VantageVue is turning freely. It could be stuck in the NE position! On Sun, Dec 10, 2023 at 7:20 PM Rob Cranfill wrote: > Thanks for looking into this. I'm glad to hear it's not a bug! :-) I can > imagine it's hard to portray t

Re: [weewx-user] Wind direction graph weirdness

Thanks for looking into this. I'm glad to hear it's not a bug! :-) I can imagine it's hard to portray the subtleties of a year's worth of data in one graph. Thanks for all your work! On Sun, Dec 10, 2023 at 7:15 AM Tom Keffer wrote: > Rob sent me a copy of his database, and I've had a chance

Re: [weewx-user] Wind direction graph weirdness

Rob sent me a copy of his database, and I've had a chance to look at it. Everything seems to be working properly. It's just that he has a lot of wind from the NE. Take a look at the date 3-Dec-2022, which is typical. Here's a histogram of wind direction. Note that this is just windDir, and it is n

Re: [weewx-user] Wind direction graph weirdness

Rob - I'm in Federal Way a mile or so south of Redondo and my graphs 'do' line up with our prevailing winds here that tend to be from the SW in this location. We rarely get wind from the NNE-SE directions. It either comes off the Sound in the Port of Tacoma or from the SW from Browns Point.

I’ll figure out how to do that and let ya know. Thanks! :-) On Tue, Dec 5, 2023 at 12:28 Tom Keffer wrote: > Good point, Jeff > > Looking at April 2023, the plot suggests wind direction is mostly SSE. The > monthly > summary >

Re: [weewx-user] Wind direction graph weirdness

Good point, Jeff Looking at April 2023, the plot suggests wind direction is mostly SSE. The monthly summary the same. Still, I'd like to see the database, if possible. -tk On Tue, Dec 5, 2023 at 11:12 AM Jeff A. D. wro

Re: [weewx-user] Wind direction graph weirdness

Looks like those are daily plots? Should each plot correspond with the dominant direction (DOM DIR), the last column of the monthly NOAA report? On Tuesday, December 5, 2023 at 8:27:30 AM UTC-7 Tom Keffer wrote: > That is an odd graph of wind direction. I looked over a one-year plot of > wind

Re: [weewx-user] Wind direction graph weirdness

That is an odd graph of wind direction. I looked over a one-year plot of wind direction at my location, and it has a similar look. But then, I live in a gorge where the wind almost always blows east or west, occasionally from the south, almost never from the north. [image: image.png] Is there som

[weewx-user] Wind direction graph weirdness

Hi, all! Longtime user, and hoping this isn't too dumb a question. I have seen the ongoing discussions about the inherent difficulty of calculating "average wind direction" and am wondering if maybe that issue is what is causing the weirdness in this long-term graph, like this (taken from h
