A Dynamical-Numerical Study of the Formation and Evolution of Large-Scale Ocean Anomalies
sea surface temperature Formation Large-Scale Ocean Anomalies
2009/2/23
To identify oceanic processes responsible for the formation and evolution of large-scale thermal anomalies, a series of initial-value model simulations are carried out using a 10-level primitive equat...
On the Interpretation of Ocean Current Spectra, Part II：Testing Dynamical Hypotheses
Ocean Current Spectra Dynamical Hypotheses
2009/2/23
Three examples are chosen to illustrate how the several spectrum representations in Part 1 can be used to test whether a proposed dynamical mechanism is supported by a given set of observations. The e...
Dynamical Forecast Experiments with a Barotropic Open Ocean Model
Dynamical Forecast Experiments Barotropic Open Ocean Model
2009/2/19
The initial/boundary value problem for the barotropic version of a quasi-geostrophic open ocean model which requires normal flow everywhere on the boundary and vorticity on the inflow is studied. Para...
Dynamical Interpretation of Satellite-Sensed Thermal Features off Vancouver Island
Dynamical Interpretation Vancouver Island Satellite-Sensed Thermal Features
2009/2/16
Two series of very high resolution thermal infrared satellite images, off Vancouver Island, are examined for evidence of baroclinic waves. A 1979 winter sequence of three images exhibits cold tongues,...
We present an analysis of 50 days of current meter and sea Revel data collected in a long narrow strait connecting the Gulf of St. Lawrence to the Atlantic Ocean. The dynamical balances implied by a s...
Testing a Dynamical Model for Mid-Latitude Sea Surface Temperature Anomalies
sea surface temperature Dynamical Model oceanic mixed layer
2009/2/5
A slab model of the oceanic mixed layer is used to predict the statistical characteristics of the sea surface temperature anomalies that are forced by day-to-day changes in air-sea fluxes in the prese...
On the Fluid Dynamical Theory of Turbulent Gas Transfer Across an Air-Sea Interface in the Presence of Breaking Wind-Waves
Fluid Dynamical Theory Turbulent Gas Transfer Air-Sea Interface Breaking Wind-Waves
2009/1/20
It is shown that in order to describe the transfer of gases in the liquid near the air-sea interface, the vertical structure of three-dimensional small-scale turbulence in turbulent patches generated ...
The Fluctuating Longshore Pressure Gradient on the Pacific Northwest Shelf：A Dynamical Analysis
longshore wind stress τ3 longshore velocity v Dynamical Analysis
2009/1/19
The majority of papers on Pacific Northwest shelf dynamics have emphasized the relationship between longshore wind stress τ3, and longshore velocity v. However, attempts to illustrate a balance of mom...
Dynamical Forecasting and Dynamical Interpolation：An Experiment in the California Current
Dynamical Forecasting Dynamical Interpolation California Current
2009/1/13
In order to perform real-time dynamical forecasts and hindcasts, three high-resolution hydrographic surveys were made of a (150 km)2 domain off northern California, providing two sets of initializatio...
The Mesoscale Spatial Structure and Evolution of Dynamical and Scalar Properties Observed in the Northwestern Atlantic Ocean during the POLYMODE Local Dynamics Experiment
Local Dynamics Experiment Mesoscale Spatial Structure Scalar Properties
2009/1/10
Dynamical properties examined in this paper are the dynamic height and the pressure on an isopycnal. Scalars are the salinity and the oxygen concentration on an isopycnal. The sea surface temperature ...
Dynamical Interpolation and Forecast of the Evolution of Mesoscale Features off Northern California
quasi-geostrophic objective analyses Mesoscale Features
2009/1/8
The series of cruises off Northern California comprising OPTOMA11, during two months in summer 1984, were specifically designed as an ocean prediction experiment. In addition to a regional survey from...
