(Vertical motion in the atmosphere has the standard name upward air velocity.) The wind speed is the magnitude of the wind velocity. A gust is a sudden brief period of high wind speed. In an observed timeseries of wind speed,  the gust wind speed can be indicated by a cell methods of maximum for the time-interval. In an atmospheric model which has a parametrised calculation of gustiness,  the gust wind speed may be separately diagnosed from the wind speed. Lot 1 uses fx  - WMO abbrev."
