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...

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...

Influence of stratification and accelerations on boundary production of vertical motion

Creator:: Park, Soon-Ung
Abstract:: The influence of boundary layer pumping on an externally-forced synoptic-scale flow is examined. The results follow earlier theories of stratified incompressible Boussinesq flow. These theories state that the spin-down time scale and the penetration depth of the influence of boundary layer pumping are inversely proportional to the stratification and directly...

Modeling of forced planetary waves in the Mars atmosphere

Creator:: Hollingsworth, Jeffery L.
Abstract:: Mariner 9 and Viking spacecraft observations during the 1970's have provided evidence for planetary-scale wave-like disturbances in the Mars atmosphere. It has been suggested that possible sources of the wave activity are dynamical instabilities (e.g., barotropic and/or baroclinic instabilities). An other candidate source is forced, quasi-stationary planetary waves. In connection...

An approach to thermal convection problems in geophysics with application to the earth's mantle and ground water systems

Creator:: Lowell, Robert P.
Abstract:: Two thermal convection problems of geophysical interest are examined, theoretically. First, convection in the earth's mantle is treated on the basis of a one-dimensional 'strip model'. This model results from further simplification of the well known 'Rayleigh model'. For homogeneous, Newtonian fluids, the strip model yields results similar to those...

Seismic ray trace techniques applied to the determination of crustal structures across the Peru continental margin and Nazca plate at 9 ̊S. latitude

Creator:: Jones, Paul Roy III
Abstract:: Seismic refraction, reflection and gravity data obtained across the Peru continental margin and Nazca Plate at 9° S. permit a detailed determination of crustal structure. Complex structures normal to the profile require the development of a ray trace technique to analyze first and later arrivals for eleven overlapping refraction lines....

Development of a rare earth element paleoproxy

Creator:: Haley, Brian Alexander, 1973-
Abstract:: This thesis describes the development of a rare earth element (REE) proxy for paleoceanographic studies of climate change. This work was done in three stages with the goal: (1) To develop a cleaning method that overcomes the problems of REE readsorption; (2) To measure pore water REEs for evaluation of...

An evaluation of the Earth Resources Technology Satellite (ERTS-1) multispectral scanner as a tool for the determination of lacustrine trophic state

Creator:: Boland, Dale H. P.
Abstract:: This study evaluates the Earth Resources Technology Satellite- One (ERTS-1) multispectral scanner (MSS) as a means of predicting lacustrine trophic state and the magnitude of selected trophic state indicators. Numerical classificatory methods are employed to ascertain the trophic character of 100 lakes in Minnesota, Wisconsin, Michigan, and New York using...

Crustal structures and tectonism in southeastern Alaska and western British Columbia from seismic refraction, seismic reflection, gravity, magnetic, and microearthquake measurements

Creator:: Johnson, Stephen Hans
Abstract:: Seismic refraction measurements along two unreversed lines indicate that the earth's crust is 26 km thick in southeastern Alaska and 30 km thick along the Inside Passage of British Columbia. The crust in southeastern Alaska, north of Dixon Entrance, consists of a layer 9 km thick with a seismic velocity...

Long baroclinic planetary waves in a nonzonal vertically sheared mean flow

Creator:: Cerovecki, Ivana
Abstract:: We consider long planetary waves of annual period linearized about a steady, wind-driven subtropical (ST) gyre circulation. The circulation divides the gyre into an eastern zone (EZ) where only the surface layer is in steady motion and a western zone (WZ) where both the surface and the middle layer are...
