  • Observations of a midlatitude squall line boundary layer wake 

    Author:Hamilton, Paul J.; Johnson, Richard H., (Richard Harlan)
    Mesoscale pressure perturbations frequently observed with mesoscale convective systems (MCS) are examined with special emphasis on the characteristics, structure, lifecycle and driving mechanism of the "wake depression" ...
  • Formulation of a bulk boundary layer model with partial mixing and cloudiness 

    Author:Randall, David A., (David Allan), 1948-; Shao, Qingqiu
    The classical cloud-topped mixed-layer model is generalized to allow for arbitrary fractional cloudiness and incomplete mixing. The boundary-layer depth and turbulence kinetic energy (TKE) are prognostically determined. ...
  • Gradient adjustment in an axisymmetric vortex 

    Author:Raghunandan, Sudama; Schubert, Wayne H.
    We consider gradient adjustment in an axisymmetric vortex. From an initially unbalanced state, the final adjusted state is obtained. Initially, the geopotential is flat and the velocity field is given by the Rankine vortex. ...
  • A polynomial representation of 6.3 μm water vapor and 4.3 μm CO2 atmospheric transmissivities 

    Author:Minnis, Patrick; Cox, Stephen K.
    The research reported in this paper describes a polynomial model formulated for the depiction of 6.3 μm H2o and 4.3 μm co2 transmissivities in the atmosphere. A six degree function utilizing a corrected optical path is ...
  • Quasi-biennial variations in the winter-time circulation of high latitudes 

    Author:Reiter, Elmar R.; MacDonald, Bruce C.
    In the years between 1952 and 1962 a quasi-biennial modulation became apparent in the total ozone values measured over Arosa, Switzerland, during spring. The stratospheric vortex behavior in the northern hemisphere during ...
