An Ocean Circulation Model Based on Operator-Splitting, Hamiltonian Brackets, and the Inclusion of Sound Waves
Publisher: American Meteorological Society
Abstract: This paper offers a simple, entirely prognostic, ocean circulation model based on the separation of the complete dynamics, including sound waves, into elementary Poisson brackets. For example, one bracket corresponds to ...
A General Method for Conserving Energy and Potential Enstrophy in Shallow-Water Models
Publisher: American Meteorological Society
Abstract: The shallow-water equations may be posed in the form df?/dt = {F, H, Z}, where H is the energy, Z is the potential enstrophy, and the Nambu bracket {F, H, Z} is completely antisymmetric in its three arguments. This makes ...
The Shape of the Main Thermocline
Publisher: American Meteorological Society
Abstract: The mean ocean density field resembles the state of maximum entropy with given values for the upper water mass, total energy and potential enstrophy. Numerical experiments confirm that the thermocline of a freely evolving ...
Poisson-Bracket Approach to the Construction of Energy- and Potential-Enstrophy-Conserving Algorithms for the Shallow-Water Equations
Publisher: American Meteorological Society
Abstract: Arakawa and Lamb discovered a finite-difference approximation to the shallow-water equations that exactly conserves finite-difference approximations to the energy and potential enstrophy of the fluid. The Arakawa? Lamb ...
Plastic Instability of Cylindrical Shells With Rigid End Closures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Solutions are obtained for the large plastic deformations of a cylindrical membrane with rigid end closures subjected to an internal pressure loading. A plastic linearly hardening material obeying ...
A Systems Engineering Approach to Harnessing Human Energy in Public Places: A Feasibility Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study analyzes the feasibility of placing modified exercise equipment in public places to enable human energy harnessing. By assessing the impacts as a system-level synthesis of economic, environmental, productivity, ...
Partially Composite Sandwich Panel Deflections
Publisher: American Society of Civil Engineers
Abstract: A continuum model for evaluating partially composite insulated concrete sandwich panel deflections with discrete shear connectors due to differential volume changes such as those caused by differences in temperature between ...
Sensitivity Study of Optimum RC Restrained End T‐Sections
Publisher: American Society of Civil Engineers
Abstract: Economical restrained end reinforced concrete T‐sections are established using an optimization routine and the strength design procedure. The objective function includes the in‐place cost of formwork, concrete, longitudinal ...
Focus on Forecasting: A Synoptic Analysis of the 25–26 January 1978 Blizzard Cyclone in the Central United States
Publisher: American Meteorological Society
Abstract: Based on detailed surface analyses and National Meteorological Center (NMC) facsimile products, the evolution of the January 1978 midwestern blizzard-producing cyclone is described. The behavior of the storm is contrasted ...
A Model for the Correction of Surface Wind Data for Sheltering by Upwind Obstacles
Publisher: American Meteorological Society
Abstract: Wakes behind 2D fences and 3D obstacles are reviewed with special emphasis on reduced mean wind speeds and sheltering effects. Based partly on Perera's study of wakes behind 2D fences, and assuming a Gaussian spread for ...
