This study concentrates on analysis of LongEZ aircraft data taken offshore
of the Atlantic Coast of the United States. Due to the land structure of the
region, it was possible to isolate the effect of narrow land on air as it flows
offshore. The...

One method of estimating the longwave radiative heating of the atmosphere is to
combine satellite observations of emitted radiances with those computed from synoptic
temperature and humidity profiles. Modeled and observed radiances are brought...

The use of efficient basis functions to model and represent flows with
internal sharp velocity gradients, such as shocks or eddy microfronts, are
investigated. This is achieved by analysing artificial data, observed atmospheric
turbulence data and...

Five years of eddy-covariance and other measurements at a mature ponderosa pine forest and a nearby young plantation are used to contrast the carbon fluxes for long-term averages, seasonal patterns, diel patterns and interannual variability, and...

A two-scale approach for the turbulent mixing of momentum in an unstable
stratified boundary layer is proposed in an attempt to eliminate existing inconsistencies
between parameterized mixing of heat and momentum. The parameterization
of the large...

The statistics describing variations of turbulent motions within the so called
inertial range of length scales depend on the scale over which the motions are varying
and the "average" rate at which the turbulent kinetic energy is being dissipated...

From both social and environmental perspectives, water is the main connection between highland and lowland processes in mountain watersheds: Water flows downhill while human impacts flow uphill. For example, in the Oregon Cascades mountain range,...

For the west coast of North America, from northern California to southern
Washington, a habitat suitability prediction framework was developed to
support wave energy device siting. Concern that wave energy devices may
impact the seafloor and...

The accurate determination of cloud cover amount is important for characterizing
the role of cloud feedbacks in the climate system. Clouds have a large influence on
the climate system through their effect on the earth's radiation budget. As...

The atmospheric radiative transfer model MOCARAT was developed and is
presented in this thesis. MOCARAT employs a Monte Carlo Technique for the
accurate modeling of band radiances and reflectances in an atmospheric system
with a ruffled ocean...

Data from the GARP Atlantic Tropical Experiment (GATE) was analysed
in an exploratory manner to discover the characteristics of mesoscale
organization of convection and it's relationship to large-scale wind profiles.
Automated methods were...

Cloud reflectivity is a function of cloud liquid water content and droplet
number concentration. Since cloud droplets form around pre-existing aerosol
particles, cloud droplet number concentration depends on the availability of
particles that can...

A global, multi-level, wave-mean flow model based on an
approximate version of the primitive equations is developed to
investigate the development of a baroclinic wave field initially
confined to a single zonal wavenumber. The effects of physical...

Numerical weather prediction models often perform poorly for weakly forced, highly variable winds in nocturnal stable boundary layers (SBLs). When used as input to air-quality and dispersion models, these wind errors can lead to large errors in...

Satellite technology represents the only technique for measuring sea surface
temperatures (SSTs) on a global scale. SSTs are important as boundary conditions for
climate and atmospheric boundary layer models which attempt to describe phenomena
of...

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...

Turbulent mixing of salt is examined in a shallow salt wedge estuary with strong fluvial and tidal forcing. A numerical model of the Merrimack River estuary is used to quantify turbulent stress, shear production, and buoyancy flux. Little mixing...

The Earth Radiation Budget Experiment (ERBE) uses Angular Dependence Models
(ADMs) to convert satellite observed radiances to radiative fluxes at the top of the
atmosphere. Owing to errors in scene identification and to the relationship between...

A method for measuring food carbon assimilation in the copepod
Calanus finmarchicus was developed, using the diatom Ditylum
brightwelli as food. The amount of particulate food carbon ingested
was determined as the difference between CHN analyzer...

Numerical simulation of the January and July global
climate with the OSU two-level atmospheric general circulation
model has generated time series of the global
distribution of selected climatic variables. Analyses of
these data for the kinetic...

The behavior of different parameterizations of mixed layer physics
when used in an oceanic general circulation model (OGCM) having coarse
resolution of the upper ocean is examined. The method of parameterization
is expected to have an important...

In plume theory it is generally assumed that a plume issuing from
a round source maintains a round cross section throughout. The consequences
of this hypothesis are significant; this fact should motivate
research into its validity. This paper...

Using a large eddy simulation (LES), the atmospheric boundary layer (ABL) is numerically modeled along 95°W from 8°S to 4°N during boreal autumn, and compared to observations from the East Pacific Investigation of Climate Processes in the Coupled...
