Thermal Inertia of Conductivity Cells: Theory
Publisher: American Meteorological Society
Abstract: The temperature anomaly of a fluid moving through circular and rectangular cylinders induced by the heat stored in the walls of these hollow cylinders is derived under the assumption of quasi-steady heat transfer. These ...
Turbulent Mixing at the Pacific Subtropical Front
Publisher: American Meteorological Society
Abstract: Some advection of water across the North Pacific subtropical front occurs by the subduction of surface mixed layers from the north side of the front underneath surface waters on the south side. Cross-frontal advection in ...
Using a Broadband ADCP in a Tidal Channel. Part I: Mean Flow and Shear
Publisher: American Meteorological Society
Abstract: This paper discusses the principles of measuring the mean velocity and its vertical shear in a turbulent flow using an acoustic Doppler current profiler (ADCP), and presents an analysis of data gathered in a tidal channel. ...
Using a Broadband ADCP in a Tidal Channel. Part II: Turbulence
Publisher: American Meteorological Society
Abstract: A four-transducer, 600-kHz, broadband acoustic Dopple current profiler (ADCP) was rigidly mounted to the bottom of a fully turbulent tidal channel with peak flows of 1 m s?1. Rapid samples of velocity data are used to ...
An Efficient Method for Determining the Significance of Covariance Estimates
Publisher: American Meteorological Society
Abstract: A technique is presented for determining if an estimate of covariance (or correlation) of two time series is statistically significantly different from zero. The technique makes no assumptions about the spectrum or the ...
Turbulence Measurements from a Towed Body
Publisher: American Meteorological Society
Abstract: A towed body suitable for measuring oceanic velocity and temperature microstructure is described. The development was motivated by i) a requirement for long times series to produce statistically reliable estimates of ...
Digital Signal Processing to Enhance Oceanographic Observations
Publisher: American Meteorological Society
Abstract: Quantization noise, the difference between a continuous physical signal and its discrete integer approximation, is an unavoidable consequence of data sampling. The problem is particularly acute for oceanographic data because ...
Turbulence Measurement from an Autonomous Underwater Vehicle
Publisher: American Meteorological Society
Abstract: Horizontal profiles of the microstructure of velocity and temperature were obtained with a large autonomous underwater vehicle (AUV) using two piezoelectric shear probes, an FP07 thermistor, and three orthogonal accelerometers ...
Turbulence Measurements with a Submarine
Publisher: American Meteorological Society
Abstract: Measurements of small-scale velocity and temperature fluctuations have been made from the research submarine Dolphin in the open ocean off San Diego, California. The important contribution of the submarine is that it ...
Turbulence Characteristics in a Tidal Channel
Publisher: American Meteorological Society
Abstract: A broadband ADCP and a moored microstructure instrument (TAMI) were deployed in a tidal channel of 30-m depth and with peak speeds of 1 m s?1. The measurements enable us to derive profiles of stress, turbulent kinetic ...
