The wind speed and direction, measured at a weather station, are used to determine the window for averaging values around a cell. 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.
Window Model Low wind speeds High wind speeds
Large window
700x700 meters, cell-centered
1100x500 meters, centered at 1000x250x100x250
Small window
175x175 meters, cell-centered
280x140 meters, centered at 210x70x70x70
