I live in the Columbia River Gorge, an extremely windy area in the summer. About 5 years ago, I moved the wind sensor from the top of my roof to a 3 meter post in a back field. Wind speeds dropped by half.
Kestrel <https://kestrelmeters.com/> makes very high quality hand-held meters. Their model 2000 <https://kestrelmeters.com/collections/all-kestrel-meters/products/kestrel-2000-wind-meter> measures wind and temperature and is under $100. Mine is over 20 years old and still functions perfectly. -tk On Sun, Mar 8, 2020 at 4:55 AM Stefan Pachlina <[email protected]> wrote: > Hello, > > hmm, i will do following. > 1) i will buy a hand-held-windmeter to check windspeed at the current > position of my weather-sensors ... maybe you are right and the position of > the windsensor is not perfect. > 2) I will move my weatherstation-outsensors to the top of the roof. > (currently its not at the top, 3m lower, but no slipstream from west, north > and south) > > You should know that I see many kilometers to the mountains. > There is nothing higher in sight (from the west) than my house.
