Air-sea heat exchange along the northern sea surface temperature front in the eastern tropical Pacific

Creator:: Thum, Nicolai
Abstract:: The atmospheric response to the oceanic forcing in the eastern Pacific along the northern equatorial sea surface temperature (SST) front is investigated in terms of sensible and latent heat flux during the 6-month period 28 July 1999 through 27 January 2000. Of particular interest is the atmospheric boundary layer (ABL)...

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...

Surface wind modification near mid-latitude ocean fronts : observational and dynamical analysis

Creator:: O'Neill, Larry W.
Abstract:: Interactions between surface winds and meanders in mid-latitude sea surface temperature (SST) fronts with horizontal length scales of 100-1000 km are investigated from satellite observations and numerical simulations. Observations from the Sea- Winds scatterometer on the QuikSCAT satellite show that the magnitude, direction, curl, and divergence of the surface wind...

A modeling study of katabatic flows

Creator:: Smith, Craig M.
Abstract:: A modeling study is undertaken to better understand the physics of katabatic flows. This study is divided into three topics; a comparison between a large eddy simulation (LES) and a mesoscale model of katabatic flows, a sensitivity study of katabatic flows to various physical parameters, and an investigation into the...

Tracer experiments in a non-uniform porous medium : implications of diffusive mass transfer on the late-time breakthrough behavior

Creator:: Freiherr von Schwerin, Claudius
Abstract:: Mass transfer processes were evaluated in an artificial, non-uniform porous medium with a power law distribution of diffusion rate coefficients obtained from physical characterization of solute and porous medium. Breakthrough curves of several pulse experiments conducted at different velocities were compared (1) to analytical expressions for concentrations at mass transfer...

Numerical and assimilative studies of the equatorial Pacific cold tongue

Creator:: Perez, Renellys Christine
Abstract:: Numerical model and assimilation experiments were conducted in the tropical Pacific Ocean to obtain a better understanding of the processes that control the cold tongue surface mixed layer temperature balance during August 1999 to July 2004. The numerical model was first applied to test two hypotheses (asymmetric background currents and...

Decomposition of absorption coefficients and decorrelation lengthscales of hydrographic and inherent optical properties in the Middle Atlantic Bight

Creator:: Simeon, Jennifer J.
Abstract:: This investigation is an exploration of the use of inherent optical properties towards further elucidation of coastal circulation processes occurring on the continental shelf and slope in the Middle Atlantic Bight, south of Cape Cod Massachusetts, during 14-Aug to 1-Sep 1996 and 25-Apr to 15-May 1997. Assessing the possibility of...

Measurement and modeling the physical controls of snowmelt in the Pacific Northwest

Creator:: Mazurkiewicz, Adam B.
Abstract:: The physical controls of snowmelt in the Pacific Northwest (PNW) are poorly understood. While there have been numerous field and modeling investigations at the plot and watershed scale, few studies have identified how the snow energy balance (EB) components vary in importance both spatially and temporally. The identification of how...

Baroclinic eddies in the Martian atmosphere : a general circulation model study

Creator:: Matheson, Mark
Abstract:: A variety of general circulation model experiments are performed to investigate the influence of seasonality and topography on the strength of baroclinic eddies in the Martian atmosphere. Three different models are used: a full physics model, a simplified physics model, and a zonally symmetric simplified physics model. All three models...
