摘要
基于2005年盘锦芦苇湿地近地面层湍流通量和微气象梯度的连续观测,研究了芦苇湿地近地面层湍流通量参数化方案。结果表明:盘锦芦苇湿地近地面层经常维持弱稳定和弱不稳定层结。在不稳定层结(-0.4<z/L<-0.01)时,盘锦芦苇湿地近地面层湍流通量计算可采用Businger-Dyer稳定度方案,在此稳定度范围之外B-D方案的适用性需要进一步验证。
Based on the turbulent flux data in atmospheric surface layer from eddy covariance tower and micrometeorological gradient data in 2005 in reed wetland of Panjin,parameterization scheme of turbulent flux was discussed.The results indicate that the atmospheric stability in atmospheric surface layer of reed wetland often maintains weakly stable or unstable stratification.Businger-Dyer stability function parameter scheme could be used to calculate turbulent flux in this region under unstable stratification(-0.4〈z/L〈-0.1),otherwise the parameterization scheme should be tested beyond this ranges as mentioned above.
