Wind Speed Bug?
Posted: Tue 07 Dec 2021 1:13 pm
Just had a squall line pass over, and I registered a 32mph average wind speed spike, which was higher than the gust. It went from 19mph to 32mph, then back down to 21mph a minute later.
Impossible for it to jump like that..
The 1 minute graph data didn't catch the 32mph, but it does show 19mph to 28mph within the space of 1 minute, then back down to 21mph a minute later.

I closed CMX and put all the records back to what they were before the spike. I reopened CMX, and it instantly puts the wind speed back to 32mph at the time I reopen the software.
I've fixed the records.
Still none the wiser as to what's going on - ie another anemometer fault, or a bug elsewhere.
