The map illustrates the average wind speed at an altitude 10 m above ground. Models run by NOAA (GFS, HRRR) calculate with 1-minute mean. However, remaining models (ICON, GEM) calculate with 10-minute mean. This can cause differences between each models. The value of the highest 1-minute sustained wind is about 14% greater than a 10-minute sustained wind over the same period. The calculation does not take into account exposed areas (hilltops, open fields) where wind speed will be greater than that in a city or valley. Localised increases in windiness during storms are also not taken into account in model calculations.
