This is my first post here, so please go easy on me. :wink: Just a bit of background. I have 2 degrees in meteorology, although I never went into the field. However my interest in the field has always remained high and I’ve always had well-respected weather stations at home. This is my first exper…

Since last night, after our storm passed and a strong cold front went through, I seem to have a new issue. Previously my Sky was reporting winds that were generally higher, but very reasonably so, than my VP2 (my Sky is in the same area, but a bit higher than the VP2 anemometer). At that point thing…

The interpretation of rain graphs given on 2018-04-18 was changed with the one provided on 2018-09-18 . The latter applies the grouping of “descriptive” intensity rates into categories with a strong bias towards users in temperate areas. This suggests a worldview of uniformity and linearity in natur…

Now that explains it perfectly, pachuquear, thanks. I kept seeing that outdated definition. David updated his post. Thanks much! Now I just need to get my wind speeds sorted out. I’m curious if others tend to get a long lag with between actual barometric pressure & humidity changes vs when those c…

I wanted to include a screenshot of my data during the rain we had yesterday. Winds were very light, yet I got a number of high gusts in the area of 30 and above. As I described above, there definitely were no gusts like that in our area. PWS & NWS stations did not show any such data nor did my VP2 …

Hi @vidguy7 , When I have wild readings in strength and direction following moist conditions I can be pretty certain it is moisture bubbles or similar at the wind sensors. It is a well known problem they are working on with coating experiments. We must be patient with that. History is here: Can Ra…

Thanks much, Ian! I kind of assumed the issue was the ponding of water, but it’s good to hear you confirm that. This morning I noticed frost on the surface too with our single digit temps, so it makes sense that this too can mess with the winds. Has anyone tried a coating of car wax? I’d think that …

[image] vidguy7: Has anyone tried a coating of car wax? I’d think that would make the surface quite slick. I’m not sure if that would prevent frost buildup or dew (although dew often occurs with light or calm winds, so the wind accuracy impact might be moot in many cases), but I wonder if it wou…

Gizmoev, in the case you cite, the issue seems to be less with the flat area under the sensors as opposed to water collection on the sensors themselves. I wonder if that was the causative factor in my increased wind velocities as I rotated the Sky unit’s mounting. I looked at the flat area and it wa…
