  Citation × Citation Citation Abstract Copy Title: Horizontal wave number spectra of temperature in the unstably stratified oceanic surface layer Author: Paulson, Clayton A., Wijesekera, Hemantha W., Huyer, Adriana, 1945- Horizontal wave number spectra of temperature in the unstably stratified oceanic surface layer were determined from measurements on a bow boom at a depth of 2 m. Spectra were estimated in the wavelength band from 2 m to 2 km, normalized in accordance with Monin-Obukhov similarity theory, and averaged in groups with similar stability parameter and fractional mixed layer depth. The shapes of the wave number-weighted oceanic spectra agree qualitatively with observed and modeled atmospheric spectra, including the wavelength of the peaks and the variation of peak wave number with stability. However, the peak spectral levels disagree by as much as a factor of two and the variation of spectral level with stability is in the opposite sense for the oceanic and atmospheric spectra. The wave number of the peak in the near neutral oceanic spectrum is similar to the wave number of the peak in the longitudinal velocity spectrum observed in the atmospheric surface layer, which is consistent with temperature acting as a passive tracer in near neutral conditions. The wave number of the peak in the free convection oceanic spectrum is similar to the wave number of the peak in the spectrum of vertical velocity observed in the atmospheric surface layer during free convection, which reflects the dynamical role played by temperature in a freely convecting boundary layer. The difference between oceanic and modeled near-neutral spectral levels at a wavelength of 2 m suggests that dissipation could be enhanced (u p to a factor of three) by surface wave breaking.

• 2. [Article] Seasonal variation in temperature, salinity, and density over the continental shelf off Oregon

  Citation × Citation Citation Abstract Copy Title: Seasonal variation in temperature, salinity, and density over the continental shelf off Oregon Author: Huyer, Adriana, 1945- Seasonal variations in the hydrography of the waters over the continental shelf off Oregon were observed in a set of hydrographic data collected along 44º39′N at intervals of a few weeks to a few months from 1961 through 1970. The temperature is determined only partly by the local heating and cooling cycle: at the surface it is low (9°C) in winter, increasing in spring, lowest in summer, highest in early fall, and decreasing in winter; near the bottom, it is highest in winter and lowest in summer. The summer minimum is associated with coastal upwelling and a strong southward geostrophic current. Variations in salinity are governed by runoff, both locally and through the Columbia River effluent, as well as by coastal upwelling and advection. Neither temperature nor salinity is negligible in determining sigma-t. In summer, sigma-t decreases with distance offshore, and isopycnals slope downward from shore; in winter, sigma-t increases with distance offshore, and isopycnals slope upward from shore. Steric sea level also slopes downward from the coast in winter, and upward in summer. Alongshore geostrophic flow is southward in summer and northward in winter. The variations in temperature, salinity, and sigma-t are caused by seasonal cycles in the surface heat balance, precipitation and runoff, the local wind, and the alongshore flow.
