How is wind speed calculated
WebSo for a month you could have a 'mean u' and 'mean v' which are small/close to zero - hence the wind speed calculated directly from these is too small. In order to calculate the monthly mean wind speed from ERA5 data, users have to download the sub-daily (hourly) u and v data, calculate the wind speeds, and then average these over the months. WebThe Beaufort Wind Scale. The Beaufort Scale is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force …
