Abstract
Wind statistics were measured within a square plot (sidelengthD = 20 m) that was sheltered on all four sides by a porous plasticwindbreak fence (height h=1.25 m, resistance coefficient kr0 = 2.4, porosity p = 0.45), standing on otherwise uniform land (sparse stubble, roughness length z0 ≈ 0.015 m). At any given point within the plot, short term wind statistics were extremely sensitive to the mean wind direction relative to thefences. Whereas the entire plot was sheltered from a wind blowingnormal to any side of the plot, whenever the wind was oriented soas to blow over a corner, wind reduction was observed onlyover a small fraction of the plot, in the near lee of the upwindfences.
