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

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 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
