The thesis examines the principal air-sea properties at Ocean
Station Vessel N (30N 140W). In a descriptive section, meteorological
and oceanographic data for N are analyzed over 20 years (1951-1970)
and 7 years (1964-1970), respectively. A...

A baroclinic, convective mixed-layer was modeled, using
water, in a laboratory convection tank identical to that
used in the free convection study of Deardorff and Willis
(1985). Baroclinicity and mean-flow shearing were achieved
by tilting the...

This study is mainly concentrated on examining the positive cloud-to-ground
lightning activity associated with Mesoscale Convective Systems. Six MCS events
which occurred during the O.K. PRE-STORM program in 1985 are studied. Data
indicating the...

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...

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,...

A simple atmosphere and ocean model of relevance to El Nino
and Southern Oscillation (ENSO) is discussed. Both the
atmosphere and ocean models are two layer, three
dimensional, linear and baroclinic, and generally follow
the Oregon State...

A study has been made of the vertical distributions and
migrations of a large number of zooplankton species at Weather
Station "P" in the Subarctic Pacific. Simultaneously towed horizontal
opening-closing nets were used for the study. The...

Patterns of beach erosion and accretion due to jetty construction
are examined for the coast of Oregon. All jetty systems are
included with the exception of those on the Columbia River, making a
total of nine systems.
All evidence indicates that...

The Indian Ocean Experiment (INDOEX) had as a primary objective
determining the radiative forcing due to anthropogenic aerosols over
climatologically significant space and time scales: the Indian Ocean during the
winter monsoon, January-March....

Anomaly timescales for the last 90 million years, derived from
marine magnetic profiles and published prior to mid-1979, are summarized,
illustrated for comparison, and critically reviewed. A revised timescale
is constructed using calibration...

The quantification and description of sea surface temperature (SST) is critically important because it can influence the distribution, migration, and invasion of marine species; furthermore, SSTs are expected to be affected by climate change....

A total of 57 core top samples from the Panama Basin were
used in a quantitative study of complete radiolarian thanatocoenoses
to determine whether surface oceanographic conditions are reflected
in the microplankton faunas deposited onto and...

The relationship between the outgoing long-wave radiation (OLR) field
over the tropical Pacific and wintertime monthly precipitation for the
western U. S. is investigated, using the mid-latitude upper-air circulation
as an intermediary. Principal...

The surface wind and stress responses to sea surface temperature (SST) are examined using collocated moored buoy and satellite observations in the Gulf Stream and the eastern equatorial Pacific. Using 17 buoy pairs, differences in the wind speed,...

This thesis investigates the feasibility of implementing a
real time quality control program into a data stream of
hydrometeorlogical data. The vast array of data used in the
forecasting of river levels and avalanches calls for a point of entry...

Simple models of transpiration, e.g., the Penman-Monteith equation, treat
atmospheric conditions as driving variables. In fact, transpiration modifies temperature
and humidity throughout the convective boundary layer, creating feedbacks that...

Occult deposition is the direct uptake of cloudwater by vegetation that comes into
physical contact with wind-driven cloud droplets. This can be a significant pathway for
hydrological and chemical fluxes from the atmosphere to some forests....

Realistic assessment of the vertical distribution of clouds, particularly the occurrence
of multi-layered systems, is critical for accurate calculations of radiative transfer in
general circulation models. Such information is also useful in the...

A multispectral retrieval method is developed on the 100 km regional scale to extract
the temperature, particle size, fractional cover and 11-μm emissivity of clouds which
may be semitransparent in the infrared based on emitted radiances. The...

The marine and freshwater fishery resources of West Africa are some of the most productive in the world, and hold vast potential to provide economic prosperity and food security for the developing nations of that region. Nevertheless, the realized...

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...

The Penn-State/NCAR MM5 mesoscale model was adapted for mesoscale
simulations of the Martian atmosphere (the OSU MMM5). The NASA Ames Mars
GCM provides initial and boundary conditions. High-resolution maps for albedo,
thermal inertia and...
