Chlorophyll variability in eastern boundary currents

Creator:: Thomas, A. C., Carr, M. E., and Strub, P. Ted
Abstract:: The first three years of SeaWiFS data (1997-2000) provide the most complete quantification to date of chlorophyll seasonal variability along the full latitudinal extent of the four major eastern boundary currents (EBCs). Comparisons to previously published chlorophyll seasonal climatologies deduced from the relatively sparse coverage provided by the Coastal Zone...

Equatorward jets and poleward undercurrents along the eastern boundary of the mid-latitude north Pacific

Creator:: Pierce, Stephen D.
Abstract:: We sharpen our view of an eastern boundary current region during the upwelling season through the analysis of several data sets. We focus on the mesoscale flow field off of northern California, observed during the Coastal Transition Zone (CTZ) experiment of 1988. First, we estimate tidal currents in the region...

Boundary layer transition

Creator:: Bakhshi, Vidya Sagar
Abstract:: Transition phenomena commonly occur in nature. These arise either due to structural or behavioral changes in the medium. Examples for these abound in all applied sciences and to mention a few of these, we have, boundary layer, elastic-plastic deformation, and shocks. The present work is devoted to the study of...

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 three component drag probe for the measurement of ocean wave orbital velocities and turbulent water velocity fluctuations

Creator:: Earle, Delph Marshall, 1913-
Abstract:: A three component drag probe has been built, calibrated, and used to measure velocities beneath deep water ocean waves and turbulence in a tidal channel. Simple variable inductance devices which may be submerged in water were used as displacement transducers and the associated electronics provided voltage outputs which were proportional...

A study of turbulence in the viscous sublayer and logarithmic region of the bottom boundary layer

Creator:: Chriss, Terry Michael
Abstract:: Detailed current profiles between the sediment-water interface and 20 cm above it reveal a viscous sublayer in the bottom boundary layer on the Oregon continental shelf. Data from three field experiments are used to test fundamental assumptions about boundary layer flow in the ocean. The first study, discussed in Chapter...

The effect of boundary geometry on internal density currents in a density stratified reservoir

Creator:: Spurkland, Torbjorn
Abstract:: The effects of boundary geometry on internal density currents in a density stratified reservoir were investigated in a laboratory model. When water was simultaneously withdrawn and admitted to the reservoir, a complex current regime was established. The general flow pattern is described, and the influence of physical variables on the...

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...

Development of a Cartesian-grid-based solver for an oscillatory boundary layer over a rough wall

Creator:: Skitka, Joseph M.
Abstract:: Predominant models for predicting rates of sediment transport face acute shortcomings when applied to coastal boundary layers. This is due to a neglect of the web of stochastic variables governing the rate of sediment dislodgement. While stochastic models do exist, the parametric extent of their validity tends to be limited,...

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...
