The wind speed and direction are used to determine the window for averaging values around a cell. Commonly, the values at a reference weather station are used. In calculations with a low wind speed, an cell-centered averaging window is used. In calculations with a high wind speed, an oblong rectangle is used for averaging, with the cell in question offset towards the far side along the line of the wind direction.
Wind speed:
- < 1.5 meter per second, the window is square and cell centered
- >= 1.5 meter per second, the window is oblong, and offset towards the wind direction, to account for the effect the wind has on factors which influence temperature.
