EUROPEAN JOURNAL OF ENVIRONMENTAL SCIENCES
The European Journal of Environmental Sciences offers a mixture of original peer-reviewed research papers, which bring you some of the most exciting developments in environmental sciences in the broadest sense, often with an inter- or trans-disciplinary perspective, focused on the European problems. The journal also includes critical reviews on topical issues, and overviews of the status of environmental protection in particular regions or countries. The journal covers a broad range of topics, including direct or indirect interactions between abiotic or biotic components of the environment, interactions of environment with human society, or environmental sustainability.

abstract

The main aim of the study is to investigate general and temporal characteristics of wind speed and direction at Ecosystem station (ES) Rajec located in southern highlands of the Czech Republic which is part of Czech Carbon Observation System (CzeCOS) network. Four years (2013-16) of eddy co-variance data from mature monoculture spruce (Picea abies) forest was used to build the wind rose and analyze the wind characteristics. The prevailing wind directions at ES Rajec were South-East and North-West and general orography of region being a highland does not impact the wind flow. Seasonal variation in the wind was observed which was mainly due to general circulation. The paper also investigates the occurrence of calm wind conditions (u < 1 m s-1) which was 6% on an average for four years and the average of day-time and night-time calm conditions were observed as 8% and 4% respectively.
