A comparison of eddy correlation and dissipation techniques for computing the fluxes of momentum, heat and moisture in the marine boundary layerPaquin, James Edward 11 June 1971 (has links)
The results of measurements of the fluxes of momentum, moisture and sensible heat in the marine boundary layer are described.
Two techniques for obtaining the fluxes are discussed. The fluxes
of these quantities are most directly obtained by the eddy correlation
method, that is, by measuring the fluctuating vertical and downstream
velocity (w and u), temperature (T) and humidity (q)
and computing the covariances wu, wT and wq. The fluxes are
also computed by obtaining a measure of the energy dissipation rate
from second-order structure functions and relating the dissipation to
the production of energy. To use the dissipation methods, values of
universal inertial-convective subrange constants (Kolmogoroff constants)
are required. Kolmogoroff constants are computed from second and third-order structure functions.
Most of the data were collected on R.V. FLIP during BOMEX
(Barbados Oceanographic and Meteorological Experiment) and during
a pre-BOMEX trial cruise near San Diego. A small amount of additional
data was collected from a site at South Beach, Oregon.
The value of the Kolmogoroff constant for velocity is consistent
with other recent observations. The temperature and humidity constants
are found to be equal within the measurement error and have
values of about 0.8. The two methods for computing the fluxes agree
on average for momentum and moisture flux. The two methods do
not agree for sensible heat flux during BOMEX although there is fair
agreement for the San Diego data. / Graduation date: 1972

Sea level response to low-frequency atmospheric pressure fluctuations along the northwestern American coastMa, Heau San 16 June 1969 (has links)
Spectral analysis was used to investigate semidaily mean sea
levels and atmospheric pressures at San Francisco, California,
Coos Bay, Oregon, and Tofino, British Columbia, in the frequency
band 0 to 0.5 cpd. Cross spectral analysis of semidaily mean sea
levels and atmospheric pressures at the three stations show that the
response of sea level to low-frequency atmospheric pressure fluctuations
is nonbarometric in the frequency band studied, and varies with
season. Cross spectral analysis of semidaily mean sea levels between
adjacent stations shows that there exists significant coherence
between the Coos Bay and Tofino sea levels within the frequency band
studied and phase difference between the stations is consistent with
the hypothesis of continental shelf waves traveling from south to
north along the coast. / Graduation date: 1970

The effects of an isolated mesoscale island on a stably-stratified airstreamKim, Jinwon 09 May 1986 (has links)
The perturbation of a stably-stratified flow by irregular
terrain is studied utilizing a seven-layer, hydrostatic, and
potential enstrophy and energy conserving primitive equation
model. The Island of Oahu, Hawaii, and the surrounding ocean area
of 130 km x 100 km is chosen as the model topography. The domain is
covered with a 5 km x 5 km mesh of 26 x 20 grid points in the
horizontal. A cyclic boundary condition is imposed at the lateral
boundaries. In order to give finer resolution to the lower
atmosphere, an irregularly spaced sigma-coordinate is used in the
vertical. Uniform east-north-easterly large-scale geostrophic
winds up to the 400 mb level are imposed in order to represent the
typical trade-wind condition.
The pressure perturbation related to the mass flux divergence
associated with the terrain irregularities, and the land-sea
temperature difference associated with the different responses to
the insolation during the daytime, are found to play a key role in
determining the velocity field in the horizontal as well as in the
vertical. Asymmetric surface pressure arises, due to the
topographically induced vertical motion, with high pressure at the
windward slope and low pressure at the downwind slope of the
island.
Daytime heating of the island induces low pressure on the
island surface. This effect is the most significant at the lee
side and inland portion of the island where the effect of cold-air
advection from the ocean is minimal. At the lee side of the
island the negative pressure perturbation induced by the daytime
heating favors the establishment of a reverse flow toward the
island, but the mountain range at the lee side of the island and
prevailing tradewind prevent this low-level inflow from
penetrating further inland. At the upwind side of the island, the
flow field is mostly determined by topographic slope rather than
by the heating of the island surface.
The perturbation to the basic flow decreases rapidly upward.
But a vertical cross-section of the horizontal divergence and the
vertical velocity fields shows well defined wave motions up to the
domain top level. The wave motions also appear downstream and
upstream of the island with reduced amplitudes away from the
island. These suggest the existence of hydrostatic mountain waves
forced by the island contour, as was predicted by previous linear
studies. The windward tilt of the wave axis shows upward
propagation of wave energy, but the wave momentum flux was
negligible. / Graduation date: 1987

Nonlinear dimensionality reduction methods in climate data analysisRoss, Ian January 2008 (has links)
Linear dimensionality reduction techniques, notably principal component analysis, are widely used in climate data analysis as a means to aid in the interpretation of datasets of high dimensionality. These hnear methods may not be appropriate for the analysis of data arising from nonlinear processes occurring in the climate system. Numerous techniques for nonlinear dimensionality reduction have been developed recently that may provide a potentially useful tool for the identification of low-dimensional manifolds in climate data sets arising from nonlinear dynamics. In this thesis I apply three such techniques to the study of El Niño/Southern Oscillation variability in tropical Pacific sea surface temperatures and thermocline depth, comparing observational data with simulations from coupled atmosphere-ocean general circulation models from the CMIP3 multi-model ensemble.
