Temperature Microstructure in Powell Lake
Publisher: American Meteorological Society
Abstract: Measurements of the vertical component of the temperature gradient in Powell Lake show phenomena similar to those observed in the ocean. The gradient is an irregular function of depth, with temperature inversions indicating ...
Estimates of the Local Rate of Vertical Diffusion from Dissipation Measurements
Publisher: American Meteorological Society
Abstract: Scaling of the turbulent energy equation suggests the balance of terms in the ocean is between turbulent production, dissipation and the loss to buoyancy. In this paper two models for the source of oceanic turbulence are ...
Temperature Microstructure in the Equatorial Atlantic
Publisher: American Meteorological Society
Abstract: Vertical profiles of temperature microstructure were collected at seven sites in the equatorial Atlantic between 24°W and 33°W, 2°N and 1°20?S. The use of three identical temperature microstructure profiles gives insight ...
Mixing in the Main Thermocline
Publisher: American Meteorological Society
Abstract: A series of profiles of velocity microstructure along 152°E in the western North Pacific Ocean were collected in May?June 1982. Large, averaged turbulent dissipation rates, ?, found in the main thermocline (400 to 1000 m) ...
Skewness of Spatial Gradients of Turbulent Dissipation Rates in the Mixed Layer
Publisher: American Meteorological Society
Abstract: Temperature ramps or microfronts are coherent tilted structures in the oceanic and atmospheric boundary layers at which there are small, but detectable, changes in mean temperature. Their presence contributes to a nonzero ...
The Influence of Wind on the Surface Layer of a Stratified Inlet: Part I. Observations
Publisher: American Meteorological Society
Abstract: Observations are described in an experiment undertaken to determine the response of a stratified inlet to changing conditions of wind, tide and runoff. Time series of conductivity profiles taken in Alberni Inlet, British ...
Surface Mixing Layers in the Sargasso Sea
Publisher: American Meteorological Society
Abstract: Observations of turbulent energy dissipation rate ? in the deep surface mixed layer at a mid-Sargasso site are presented: two occupations of this site include a large range of local meteorological forcing. Two frontal ...
Turbulence Characteristics and Dissipation Estimates in the Coastal Ocean Bottom Boundary Layer from PIV Data
Publisher: American Meteorological Society
Abstract: Turbulence characteristics in the coastal ocean bottom boundary layer are measured using a submersible Particle Image Velocimetry (PIV) system with a sample area of 20 ? 20 cm2. Measurements are performed in the New York ...
Pacific Equatorial Turbulence: Revisited
Publisher: American Meteorological Society
Abstract: Turbulence measurements from the central equatorial Pacific in February 1982 have been analyzed and compared to synoptic CTD and current velocity profiles and current meter data. These suggest considerably more time (if ...
Horizontal Distribution and Characteristics of Shear Layers in the Seasonal Thermocline
Publisher: American Meteorological Society
Abstract: High-resolution velocity shear, CTD, and microstructure measurements were made simultaneously from the research submarine Dolphin in Monterey Bay in October 1984. During three consecutive dives, the Dolphin cycled between ...
