Under light wind conditions, the alternation of daytime
heating and nighttime cooling creates a characteristic
response in the oceanic boundary layer known as the diurnal
cycle. The Mellor/Yamada Level II turbulence closure model is
used to analyze this response pattern.
The diurnal cycle has three phases. During morning and
early...
A finite difference scheme is employed to solve the
integral form of the momentum, continuity and heat
equations, for a two layer ocean bounded by a coastline.
The momentum equations include the turbulent dynamics and
the time-dependent and nonlinear terms in both the
cross-shelf and alongshelf directions. The system of...
A Kalman filter was developed to recover information on short period variations of ocean circulation from the satellite altimeter signals for the North Pacific Ocean. The ocean circulation at each grid point is specified by three variables: sea level height h, zonal velocity u, and meridional velocity v. In our...
This research examined the diets of angora goats on a sagebrush bunchgrass rangeland. Research objectives were to 1) determine the effects of a positive conditioning method on both mature and immature angora goats; and 2) to quantify plant selection and provide preliminary information as to the potential for using goats...
Several methods are developed for analyzing data containing a highly variable internal tide. In particular, the methods are aimed at the analysis of moored observations with relatively few measurements in the vertical. The analysis depends upon an "elliptical decomposition" that is a generalization of the familiar "rotary decomposition." The technique...
The variability of sea level and surface geostrophic currents in the Southern Ocean is investigated from the first 26 months of unclassified Geosat altimeter data (November 1986 to December 1988). Because of problems unique to Geosat, it has been necessary to develop new techniques for analyzing the height data. These...
The location of the Antarctic Polar Front (PF) was mapped over a 7-year period (1987-1993) within images of satellite-deprived sea surface temperature. The mean path of the PF is strongly steered by the topographic features of the Southern Ocean. The topography places vorticity constraints on the dynamics of the PF...
