Daily Average Wind Speeds at Bingley
February 9, 2024
By Paul Homewood
Further to the post about wind speeds at Bingley, I also obtained data on daily mean windspeeds:
The daily means, ie the means of hourly averages each day, also show a clearly declining downwards trend when looking at the windiest day each year.
Top of the list is 15th December 1982, with an average of 32 kts. By the way, the monthly weather reports state that the highest value for hourly wind at Bingley that day was 42 kts.

NOT A LOT OF PEOPLE KNOW THAT 
Thanks Paul, good to clear up the relationship between average speeds and gusts.
Keep up the great work.
So the trend at Bingley is down. I suggest that the rising woodland in the immediate area is soaking up some of the speed and the abundant Co2.
Wind farms themselves will reduce the energy level in the wind of course.
Im still unsure if that’s true. Wind is a movement from one area to another that ends when the physical cause ends. If wind farms remove some of the energy, I think (guess) that the wind will blow for longer/stronger because it still needs to satisfy the physical cause.
It may blow for longer, but not stronger. Energy and momentum are extracted by the windmills. The wake has lower pressure and velocity, and has to be back filled by wind that didn’t go through the turbine. The wind downstream is slower, so it takes longer to equalise the pressure and temperature differences that set it up. But being slower, less energy is available for the next wind farm.

That Paul Homewood confusing everybody with facts again.
Using their own data to destroy their propaganda.
Great work Paul, what about the next step, to look at the lowest mean speed over that period, and the absolutely lowest periods?
Those are the periods that threaten to crash the grid even if the weekly, or monthly average speed is adequate to service the power supply.
Amazingly the Dunkelflautes were invisible to the met men and the power planners even though mariners would have known about them for ever, likewise millers in recent centuries, and even recreational sailors.
Dunkelflautes only appeared in Wikipedia in 2019 and wind droughts have no entry.
