Using rotated principal component analysis, 200mb wind data from
the First GARP Global Experiment are analyzed in the East Asia winter
monsoon region. It is found that there exist slowly eastward-moving
disturbances with a wind-speed maximum...

The energetics of large amplitude, high-frequency nonlinear internal waves (NLIWs) observed over the New Jersey continental shelf are summarized from ship and mooring data acquired in August 2006. NLIW energy was typically on the order of 10⁵...

Computer models are used to simulate the nonlinear formation of images of obscurations in laser beams. The predictions of the model are found to be in good agreement with measurements conducted in the nonlinear regime corresponding to a typical...

Due to distortion of airflow streamlines, flow velocities and droplet size distributions measured around a moving aircraft can differ from freestream conditions. This can complicate measurements made from aircraft platforms. Potential flow...

Aerosol particles can act as cloud condensation nuclei and thereby influence the number and size of droplets in clouds. Consequently, anthropogenic particles have the potential to influence global climate by increasing cloud albedo and decreasing...

In a cloud formed during adiabatic expansion, the droplet size distribution will be systematically related to the critical supersaturation of the cloud condensation nuclei (CCN), but this relationship can be complicated in entraining clouds....

Condensed water content (CWC) measured using a counterflow virtual impactor (CVI) with a Lyman-α hygrometer downstream is compared with that measured by other airborne instruments (a hot-wire probe, a PMS FSSP, and a PMS 2D-C). Results indicate...

Upper air soundings taken every three hours are used
to examine a cold front of average intensity over a period
of 24 hours. Vertical cross sections of potential temperature
and wind and horizontal analyses are compared and adjusted
until they are...

Meteorological aspects of geothermal energy development are first
discussed in general terms. An instructive case study is then presented
of a hypothetical 100 MW geothermal electrical generating plant at
a site near Vale, Oregon. Long-term...

This thesis involves the interpretation of gravity and other
potential field anomalies caused by layers of varying thickness. The
partial differential equations of potential field theory are reviewed for
gravitational and magnetic force fields. A...

Forecasts of the likelihood of occurrence of various
amounts of precipitation are very important, since
excessive precipitation amounts over relatively short time
periods can have adverse effects on public safety and
economic efficiency, As a...

Multiple linear regression was used to develop equations for 12-,
24-, and 36-hour surface wind forecasts for the wind energy site at
Goodnoe Hills. Equations were derived separately for warm and cool
seasons. The potential predictors included LFM...

This study examined the foraminifera and the ecologic conditions
of the benthic environment of the Oregon shelf and the uppermost slope
(75-550 m depth) between 143°45' N and 144°40' N. Seasonal collections
monitored the near-bottom marine...

Ice concentrations in orographic wave clouds at temperatures between −24° and −29°C were shown to be related to aerosol characteristics in nearby clear air during five research flights over the Rocky Mountains. When clouds with influence from...

Using the counterflow virtual impactor, a new instrument for sampling cloud droplets, measurable levels of light-absorbing material were found to exist inside droplets in stratocumulus clouds off the coast of southern California. Eighty percent of...

Many soil-derived particles dominated by insoluble material, including Saharan dusts, are known to act as ice nuclei. If, however, dust particles can compete with other atmospheric particle types to form liquid cloud droplets, they have a greater...

Many investigations using satellite data have determined that aerosol optical depth and cloud cover are correlated and some have interpreted the correlation as evidence of an aerosol indirect effect on clouds. This study uses in situ aircraft...

A two-dimensional numerical mesoscale model, which ic1udes
radiative and turbulent transfers, has been constructed to study the
formation, development and dissipation of coastal stratus cloud
under an inversion. In the model, the delta-Eddington...

Two land breeze events occurred off the Oregon coast on the
nights of April 19th and 20th, 1973. An array of four moored toroid
buoys and one land station recorded the effect of the land breeze event
on the surface mesoscale wind and temperature...

Hydrographic data and drogue observations were used to describe
the circulation and water masses in the upper 500 meters of
the region of the entrance to the Gulf of California in the early spring
of 1970.
The thermohaline structure of the water...
