It looks like WU has added some new parameters to their upload protocol recently.

windspdmph_avg2m - [mph 2 minute average wind speed mph]
winddir_avg2m - [0-360 2 minute average wind direction]
windgustmph_10m - [mph past 10 minutes wind gust mph ]
windgustdir_10m - [0-360 past 10 minutes wind gust direction]
I dont think these were there before. The graphs are probably plotting using these while the software is not sending these causing the issue. I have raised it in weewx google group also where weewx owner has acknowledged this and created a new issue.
Not sure what happens with other software with rapidfire.
Interesting but I don't think that is the problem with the wind graph. If you mouse over the wind graph you'll notice that it is plotting the graph in 5 minute increments the same as the table chart data. The problem is that the table chart data looks correct and the graphs are not plotting what the table charts say. They should match and they don't.
Rapidfire or not shouldn't present a problem plotting no matter which variables are used.
WU needs to decide what the graph plot represents.
- The Average of 5 minutes of Rapidfire
- The Maximum of 5 minutes of Rapidfire (the right choice)
- The First or Last data point from the previous 5 minutes of Rapidfire
I can tell you that the First or Last is not good and I hope they aren't doing that. The Average of 5 minutes of Rapidfire is what the Old WU wind graph did. I believe that the wind graph at least for speed is using the Maximum of of the last 5 minutes of Rapidfire. It still doesn't match the Table Chart data. Now for wind gusts that is totally totally messed up and there is no sense what they've screwed up there.
If WU has introduced these new variables that is fine but it shouldn't be necessary to use them. If a station uses the original variables then it is up to WU to do the math and translate instantaneous wind speed to 5 minute Tables and Graphs. I don't think they are doing that. Which is a problem.
It shouldn't be necessary to use these new variables if Rapidfire is being used. The whole point of Rapidfire is to see instantaneous wind speed and gusts as calculated by your console. WU needs to fix Rapidfire data and plot and chart that correctly into 5 minute increments. It's totally up to them to fix this. Using the new variables does not fix the problem.
If one wanted to change to use these new variables with Rapidfire it would be okay. But then you'd be live reporting on previous 2 min speed and 10 minute gusts. It would be like a delayed decay of max for the previous 2 and 10 minutes for each. It's a personal preference thing, no right or wrong here. Still WU would need to properly translate that to 5 minute graphs and tables just the same.
That is my opinion anyway.
