Anyone know how to calculate windspeed ?

[Natt]

Here is my question...

I had set up a wind speed and wind direction sensor ( Anemometer )
but I would like to have all the data in excel spread sheet by using a formula to calculate the data and be able to insert my own number without using data from the sensor give me.

What formula should I use ?

I would like to know how are these data related to each other ?

Up draft, Down draft, Wind speed, Wind direction

Some people told me to use Yamartino Method but I'm still lost T_T

What formula should I use ?

Thank you :!)

If I understand you correctly, you want a formula to calculate the wind speed (title of this thread) using the "data" of up draft, down draft and wind direction. I don't think such formula exists. It's looking for a formula to calculate the speed of the car if you know whether it's going uphill or downhill and in what compass heading.
