Název v původním jazyce

Aerodynamic characteristics and wind direction above a spruce forest stand

Popis výsledku v původním jazyce

In this paper an analysis of the wind direction and wind speed profile measurements in and above young spruce forest stand is presented. The needed experimental data were obtained by measurements during the growing season of the year 2004 in the localityBílý Kříž in Moravian-Silesian Beskydy Mts., Czech Republic. The experimental site consisting of two plots Fd and Fs with different tree density is created by the monoculture of a Norway spruce stand. The wind direction was measured continuously. It wasfound out the prevailing wind above the spruce forest stand came from SSW direction, in more than 50% of all analysed wind directions. The reason is in the local orographic broken terrain. Wind speed profiles were measured in Fs plot continuously at different levels. For the analysis 837 profiles were selected, which fulfilled the condition: u (9m) > 1,0 ms-1. In that case we can assume, that the wind speed profiles were analysed in the conditions of the turbulent development.
