  1. 11. Convection in large scale numerical models : parameterization and forecasts of precipitation probability

    Författare :Ulla Hammarstrand; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis deals with the problem of including the effects of moist convection in the atmosphere in a large scale numerical forecast model and how to interpret and evaluate the predicted convective precipitation.Two methods for parameterizing convection in a large scale numerical forecast model are tested to find the most appropriate one for precipitation forecasts in the mid-latitudes.

  3. 12. Turbulence Measurements in a Natural Convection Boundary Layer and a Swirling Jet

    Författare :Abolfazl Shiri; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; swirl; constant current bridge; high Rayleigh number; natural convection; Jet; cold-wire thermometry; vertical cylinder; laser Doppler anemometry; turbulent boundary layers;

    Sammanfattning : Two sets of experimental measurement were carried out on an axisymmetric swirling jet flow and a natural convection boundary layer. In the first experiment, the far field of an incompressible swirling jet, discharged into a quiescent ambient has been studied using laser Doppler anemometry. LÄS MER
