Irregular Grid Finite-Difference Techniques: Simulations of Oscillations in Shallow Circular Basins
Publisher: American Meteorological Society
Abstract: Finite-difference techniques for irregular computational grids are presented. Successful simulations of transient normal mode oscillations in shallow circular basins, where analytic solutions are known, demonstrate that ...
Comparison of Finite-Element and Finite-Difference Schemes. Part II: Two-Dimensional Gravity Wave Motion
Publisher: American Meteorological Society
Abstract: 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 computational economy. The ...
Comparison of Finite-Element and Finite-Difference Schemes. Part I: One-Dimensional Gravity Wave Motion
Publisher: American Meteorological Society
Abstract: 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 oscillations reveal that ...
Estimating Salinity between 25° and 45°S in the Atlantic Ocean Using Local Regression
Publisher: American Meteorological Society
Abstract: The empirical relationship between salinity and temperature in the South Atlantic is quantified with the aid of local regression. To capture the spatial character of the TS relationship, models are fitted to data for each ...
A Solvable Model of “Shear Dispersion”
Publisher: American Meteorological Society
Abstract: Shear dispersion results from vertical shear of horizontal velocity and vertical mixing, features which cannot be included explicitly in one-layer, vertically integrated models. The parametric description of shear dispersion ...
Climatic Fingerprints, Patterns, and Indices
Publisher: American Meteorological Society
Abstract: The purpose of this note is to point out that Hasselmann's optimal fingerprints for detecting climatic change follow from the geometrical interpretation of covariance as an inner product.
Climatic Indices, Principal Components, and the Gauss-Markov Theorem
Publisher: American Meteorological Society
Abstract: If indices are to be used as the variables predicted by linear statistical models, it is important to be able to recover as much local information as possible from the values forecast for the indices. Here it is shown that ...
