  • Turbulence structure within an inclined laboratory convection tank

    Creator:
    Nance, Jon D.
    Abstract:
    A baroclinic, convective mixed-layer was modeled, using water, in a laboratory convection tank identical to that used in the free convection study of Deardorff and Willis (1985). Baroclinicity and mean-flow shearing were achieved by tilting the tank by an angle of 1O⁰. The resulting mechanical-production rate of turbulence kinetic energy...

  • A numerical study of mesoscale motion in the atmospheric mixed layer

    Creator:
    Ruscher, Paul Harold
    Abstract:
    The numerical modeling of motions in the atmosphere's planetary boundary layer (PBL) is a challenging task. In general, the boundary layer interacts with both the overlying atmosphere and the underlying land or water surface in a complex manner. Random turbulence is also present in the PBL which precludes exact prediction...

  • Numerical simulation of planetary boundary-layer evolution and mesoscale flow over irregular terrain under daytime heating conditions

    Creator:
    Ueyoshi, Kyozo
    Abstract:
    The influence of irregular terrain on the evolution of the daytime planetary boundary layer (PBL) and meso-β scale dry circulations is studied using two three-dimensional hydrostatic σ-coordinate models with different approaches for the PBL parameterizations; the 4-layer model uses the mixed-layer (bulk-layer) approach, while the 7-layer model adopts the eddy-diffusivity...
