Entry: Aerodrome mean wind speed

URI: http://codes.wmo.int/common/quantity-kind/aerodromeMeanWindSpeed

The mean speed of the wind over the 10-minute period immediately preceding the observation. When the 10-minute period includes a marked discontinuity in the wind characteristics (1), only data after the discontinuity shall be used for obtaining mean wind speed, hence the time interval in these circumstances shall be correspondingly reduced.

note (1) A marked discontinuity occurs when there is an abrupt and sustained change in wind direction of 30° or more, with a wind speed of 5 m s-1 (10 KT) or more before or after the change, or a change in wind speed of 5 m s-1 (10 KT) or more, lasting at least two minutes.
