Vertical profiles of the structure parameter of temperature in the stable, nocturnal boundary layer, part 1
Abstract
Vertical profiles of the structure parameter of temperature (C sub T)sq in the stable, nocturnal boundary layer are obtained with the models described by Nieuwstadt (1984, 1985), Sorbjan (1986) and Duynkerke and Driedonks (1987). These theoretical profiles are compared with observed profiles obtained at the meteorological mast at Cabauw, The Netherlands. From the observations it is found that (C sub T)sq is large in the surface layer and small at the top of the boundary layer. Observations during nights with moderate geostrophic winds or during the first few hours of nights with a high geostrophic wind show a continuous decrease of (C sub T)sq from surface layer to the top of the boundary layer. Observations done later at nights with a high geostrophic wind show the development of a maximum of (C sub T)sq at three quarters of the boundary layer. From the comparison with the models it is concluded that the observed profiles are best described by the model of Duynkerke and Driedonks.
