Dynamics of a differentially-heated geophysical boundary layer

Creator:: Smith, Bartlett Knapp
Abstract:: An analytical two-layer model consisting of a time-dependent stratified boundary layer topped by stratified free flow is developed in order to study atmospheric boundary layer production of vertical motion. To avoid use of a constant eddy viscosity, the boundary layer equations are layer-integrated over a fixed depth, and surface stress...

Parameterization of shallow convection in the boundary layer

Creator:: Chu, Cheng-tsong
Abstract:: A shallow convection scheme is derived from several data sets (BOMEX, GATE, AMTEX, BLX83) and developed for the OSU 1-D boundary layer model. Results of the model structure and characteristics of the saturation point (SP) profile are compared against the constant cloud diffusivity scheme of Tiedtke (1983) and the ECMWF...

Linking dynamics of the near-surface flow to deeper boundary layer forcing in the nocturnal boundary layer

Creator:: Smoot, Alexander R.
Abstract:: Weak-wind flow in the nocturnal boundary is one of the most poorly understood problems in the field of meteorology. The understanding of weak-wind flows is essential for the improvement of regulatory dispersion models which are currently rendered invalid under weak-wind conditions and stable stratification. Recently there have been increased efforts...

Atmospheric boundary layer coupling to midlatitude mesoscale sea surface temperature anomalies

Creator:: Thum, Nicolai
Abstract:: This thesis examines the mechanisms that couple the monthly-averaged atmospheric boundary layer (ABL) to open-ocean sea surface temperature (SST) perturbations on scales of 50-500 km. The observed positive correlation between surface wind speed anomalies and SST anomalies is successfully simulated using the Weather Research and Forecasting (WRF) model. In numerical...

A study of the relationship between ageostrophy and dynamical periodicities of the tropical Pacific Boundary Layer

Creator:: McCandlish, Cole B.
Abstract:: Eight years (1980-87) of twice-daily high-resolution radiosonde data from a tropical mid-Pacific island station are analyzed to generate time series of the planetary boundary layer (PBL) top pressure, an ageostrophic parameter (related to the divergence), and a parameter of mean PBL specific humidity. Sample spectra of these time series are...

An examination of structure and parameterization of turbulence in the stably-stratified atmospheric boundary layer

Creator:: Ruscher, Paul Harold
Abstract:: The very stable boundary layer is a region of the atmosphere typified by large vertical gradients of temperature and momentum. Analysis of very stable atmospheric flows is complicated by the presence of nonlinear interactions among gravity waves, shear-driven overturning circulations, two-dimensional vortical modes and intermittent turbulence in various stages of...

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...
