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...

Observational studies of stable nocturnal boundary layers: intermittent turbulence, sensible heat budgets and observational errors

Creator:: Nakamura, Reina
Abstract:: Atmospheric boundary layers become stably stratified at night over land when the surface becomes colder than the air layer above. In stable nocturnal boundary layers (SNBL), turbulence becomes weak and intermittent, terrain-induced phenomena such as drainage currents or gravity-waves emerge and the surface heterogeneity is enhanced. Because of their complexity...

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...

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...

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...

The field edge flux paradox

Creator:: Barr, Colleen M.
Abstract:: Precision irrigation has made spatially explicit water management a reality. However, detailed knowledge about the spatially variable evapotranspiration is often unavailable. One example location where we can begin to understand the impact of spatial variability on evapotranspiration is at the field edge, which contains a sharp discontinuity in surface conditions....

Bright air : geoprocessing thermal imagery to map the nocturnal dynamics of the boundary layer in a mountain valley

Creator:: Johnson, Christopher
Abstract:: A thermal infrared (TIR) camera is used to remotely sense the foliage temperature in a mountain valley. The foliage temperature is used as a proxy for air temperature and can be used to study and map the dynamics of the nocturnal, weak-wind boundary layer in this valley. All radiative flux...
