Two-Dimensional Free Oscillations in Natural Basins
Publisher: American Meteorological Society
Abstract: A method is designed to calculate normal modes of natural basins. The purpose is to determine the period and configuration of free oscillations in a way that provides for the full two-dimensionality of the problem, and ...
Normal Modes of the Atlantic and Indian Oceans
Publisher: American Meteorological Society
Abstract: Normal modes are calculated for a homogeneous ocean occupying a connected domain consisting of the North Atlantic, South Atlantic, and Indian Oceans. Coastal configuration and bathymetry are resolved on a grid of 675 ...
Normal Modes of the World Ocean. Part I. Design of a Finite-Element Barotropic Model
Publisher: American Meteorological Society
Abstract: The linearized primitive equations for a barotropic world ocean are discretized by means of first-order, piecewise-linear finite elements. Surface elevation and Stokes/Helmholtz velocity potentials are adopted as dependent ...
The ENIAC Computations of 1950—Gateway to Numerical Weather Prediction
Publisher: American Meteorological Society
Abstract: The first numerical weather prediction was made on the ENIAC computer in 1950. This lecture gives some of the historical background of that event and a partially narrative account of it.
THE INCREASE OR DECREASE OF MEAN-FLOW ENERGY IN LARGE-SCALE HORIZONTAL FLOW IN THE ATMOSPHERE
Publisher: American Meteorological Society
Abstract: The transfer of energy between mean flow and disturbance for a barotropic non-divergent fluid is investigated by solution of the vorticity equation to obtain initial tendencies corresponding to assigned flow-patterns. The ...
Effects of Multiple Connectivity on a Finite-Element Barotropic Model
Publisher: American Meteorological Society
Abstract: A finite-element model recently designed for calculation of oceanic normal modes is amended here with a prescription for the proper treatment of multiple connectivity, the main effects of which are likely to be located in ...
THE SPECTRAL FORM OF THE VORTICITY EQUATION
Publisher: American Meteorological Society
Abstract: The nonlinear aspects of the vorticity equation for two-dimensional planetary circulations of the earth's atmosphere may be studied by expansion of the solution in spherical surface harmonics. Some of the main mathematical ...
AN APPROXIMATION TO THE PRODUCT OF DISCRETE FUNCTIONS
Publisher: American Meteorological Society
Abstract: If one regards a discrete function as a vector, the ?best? approximation to the product of two discrete functions (defined for the same set of values of the argument) is not necessarily the ordinary scalar product. The ...
Normal Modes of the World Ocean. Part IV: Synthesis of Diurnal and Semidiurnal Tides
Publisher: American Meteorological Society
Abstract: Diurnal and semidiurnal tides of second and third degree are synthesized from 60 normal modes with period in the range 8 to 96 h. Diurnal tides, especially those of second degree, can be represented by remarkably few modes. ...
THE PREDICTION OF SURGES IN THE SOUTHERN BASIN OF LAKE MICHIGAN
Publisher: American Meteorological Society
Abstract: A summary of numerical computations is presented, in a form designed to aid in operational prediction of surges in the Southern Basin of Lake Michigan. The computations are based upon a dynamical model in which the surge ...
