Kód oboru RIV: EH - Ekologie - společenstva

Parametrization of the zero plane displacement and the roughness length on air flow was based on the analysis of the vertical wind speed profiles measured in and above young spruce forest during the growing seasons 1997 - 2000. It was found, that this stand was in an aerodynamic unsteady state and the zero plane displacement values were independent or only insignificant dependent on the wind speed and dependent only on the mean height of forest stand.
