摘要

本研究的主要目的是调查位于捷克共和国南部高地的生态系统站(ES)Rajec的风速和风向的一般和时间特征,该站是捷克碳观测系统(CzeCOS)网络的一部分。利用四年(2013-16)的成熟单作云杉(Picea abies)林的涡共方差数据建立了风玫瑰,并分析了风的特征。ES Rajec的主导风向为东南和西北,该地区作为高地的总体地形不会影响气流。观察到风的季节性变化,这主要是由于环流。本文还调查了四年来平均6%的平静风况(u<1 m s-1)的发生率,白天和夜间的平均平静风况分别为8%和4%。

Wind characteristics recorded at the Czech Carbon Observation System (CzeCOS) site Rajec
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.

期刊介绍: The European Journal of Environmental Sciences offers a mixture of original refereed 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 / 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, etc. The journal is published twice a year (June, December).
