Comparison of extended and ensemble based Kalman filters with low and high resolution primitive equation ocean models
Kalman filters low and high resolution primitive equation ocean models
2009/11/11
Kalman filters are widely used for data assimilation into ocean models. The aim of this study is to discuss the relevance of these filters with high resolution ocean models. This was investigated thro...
A comparison of the performance of 4D-Var in an explicit and implicit version of a nonlinear barotropic ocean model
4D-Var explicit and implicit version nonlinear barotropic ocean model
2009/11/3
A comparison is made of the performance of the four-dimensional variational data assimilation (4D-Var) method in an explicit and implicit version of a barotropic quasi-geostrophic model of the wind-dr...
A Comparison of Observed and Numerically Simulated Circulation in the Cayman Sea
Numerically Simulated Circulation Cayman Sea
2009/3/24
An observational and numerical study of the circulation in the Cayman Sea is presented. Data taken in three different years suggest a common February to May circulation pattern. A well-developed curre...
Comparison of Model and Observed Currents in Lake Michigan
Federal Water Pollution Control Agency Lake Michigan
2009/3/7
Results from four deterministic numerical-hydrodynamical models for Lake Michigan are compared to data from the field program of the Federal Water Pollution Control Agency (FWPCA) for September 1963, ...
A Three-Dimensional Model of Lake Ontario's Summer Circulation I. Comparison with Observations
A Three-Dimensional Model Lake Ontario's Summer Circulation
2009/3/7
Observations of Lake Ontario during the International Field Year for the Great Lakes are used to develop a. three-dimensional numerical model for calculating temperature and current. The model has a v...
A Comparison of Finestructure Spectra from the Main Thermocline
Finestructure Spectra Main Thermocline
2009/3/7
Large numbers of STD casts taken during five cruises to the same location in the central North Pacific permitted the separation of the temperature profile into mean T¯ (z) and fluctuating T′(z) c...
A Comparison of Cyclonic Ring Structures in the Northern Sargasso Sea
Cyclonic Ring Structures Northern Sargasso Sea
2009/2/23
Field observations provide a data base that supports a comparison of ring structures in terms of the background Sargasso Sea environment. Five ring surveys, three from the 1967 sequence, a big baby ri...
Numerical Computation of Three-Dimensional Circulation in Lake Erie：A Comparison of a Free-Surface Model and a Rigid-Lid Model
Three-Dimensional Circulation Free-Surface Model Lake Erie
2009/2/23
The three-dimensional time-dependent flow in the Western Basin of Lake Erie has been calculated numerically by means of both a two-mode free-surface model and a rigid-lid model. Detailed comparisons o...
Comparison of Finite-Element and Finite-Difference Schemes. Part II：Two-Dimensional Gravity Wave Motion
Finite-Element Finite-Difference Schemes Two-Dimensional Gravity Wave Motion
2009/2/23
Irregular grid finite-difference techniques lead to equations similar to those obtained using finite-element techniques. The simpler finite-difference equations offer the advantage of greater computat...
Comparison of Finite-Element and Finite-Difference Schemes. Part I：One-Dimensional Gravity Wave Motion
Finite-Element One-Dimensional Gravity Wave Motion Finite-Difference Schemes
2009/2/23
The finite-element scheme requires more computational expense because it is time-implicit and because it requires a smaller time step than the finite-difference scheme. Simulations of normal mode osci...

Tides Setup Bottom Friction Shallow Semi-Enclosed Basin
2009/2/11
This is the second in a series of papers reporting the results of a study of tides, setup and bottom friction in the Bight of Abace, Bahamas. The extensive field data reported in Part I of the series ...

Integral Hydrodynamic Model Physical Characteristics Upper Ocean Frontal Dynamics Comparison
2009/2/11
The physical characteristics of a model of an upper ocean density front are examined and compared to observations. The model was developed and analyzed in a companion paper. It applies to the mean cir...
A Comparison of Long Coastal Trapped Wave Theory with Observations off Peru
Long Coastal Trapped Wave Theory Observations off Peru
2009/2/8
The agreement between coastal trapped wave theory and observation is studied for the case of observations made off Peru during the 1977 CUEA JOINT-II experiment. Wave properties are calculated using a...
