Abstract: Monin-Obukhov similarity applied to the real part of the refractive index variance n?2 is discussed. It is shown that, because the observed correlation coefficient rTQ between temperature and humidity is less than unity, ...

Abstract: A large eddy simulation model was used to generate and compare statistics of turbulence during nonpenetrative and penetrative dry convection. In penetrative convection dimensionless vertical velocities in updrafts were ...

Abstract: Effects caused by variation of the potential temperature lapse rate Γ in the free atmosphere are examined based on a ?large eddy simulation? model of the shear-free convective atmospheric boundary layer. The obtained results ...

Abstract: The paper investigates similarity of scalar fields in a horizontally homogeneous, cloud-free, shearless, convective mixed layer. The concept of the ?bottom-up? and ?top-down? decomposition is verified for both passive and ...

Abstract: A simple, steady-state, numerical model is used to examine the Rossby-number similarity theory of the atmospheric boundary layer over a slightly inclined terrain. The model confirms the similarity predictions. The ...

Abstract: The ?flux based? local scaling in the stably stratified boundary layer is valid only in cases with strong, continuous turbulence, when the gradient Richardson number Ri is constant and subcritical. To extend the local ...

Abstract: The structure of the steady-state flow, homogeneous along an inclined, flat, underlying surface, is studied. On the basis or the atmospheric boundary layer equations the resistance laws of geostrophic drag and heat transfer ...

Abstract: The similarity theory of an atmospheric boundary layer over a slightly inclined terrain, discussed in an earlier paper (Sorbjan, 1983) is extended to the case of geostrophic wind varying with height. The forms of resistance ...

Abstract: A parameterization method developed by Sorbjan is used to derive expressions for various statistical moments of vertical velocity, potential temperature, and humidity (or passive scalar concentration) in the convective ...
