Surface wind calculation
|
Just read the discussion and found why NHC is going below the recon obs with regard to wind speed. But they say that 56 kts winds were found at 1500ft, which would equate to 48 kts at the surface, does anyone know what formula they are using to calculate this, or how to determine sfc winds from the flight level winds that are given?
