RISApplication of Continuous Dynamic Grid Adaption Techniques to Meteorological Modeling. Part II: Efficiency
Publisher: American Meteorological Society
Abstract: The continuous dynamic adaptive grid (CDGA) technique has been shown to yield significant improvements in solution accuracy over equivalent fixed-grid methods. In this paper we consider the related question of efficiency; ...
Comparing Schemes for Integrating the Euler Equations
Publisher: American Meteorological Society
Abstract: Over the years there have been a number of studies comparing the relative merits of semi-Lagrangian and Eulerian schemes. These studies, which continue to appear in the literature up to the present, almost invariably ...
Application of Continuous Dynamic Grid Adaption Techniques to Meteorological Modeling. Part I: Basic Formulation and Accuracy
Publisher: American Meteorological Society
Abstract: The continuous dynamic grid adaption (CDGA) technique developed in astrophysics and aeronautics is applied, to our knowledge, for the first time to meteorological modeling. The aim of CDGA is to improve the accuracy of ...
An Interactive Analysis and Forecast System for Tropical Cyclone Motion
Publisher: American Meteorological Society
Abstract: The design concept and operational trial of a fully interactive analysis and numerical forecast system for tropical-cyclone motion are described. The design concept emphasizes an interactive system in which forecasters can ...
ACCESS-TC: Vortex Specification, 4DVAR Initialization, Verification, and Structure Diagnostics
Publisher: American Meteorological Society
Abstract: he Australian Community Climate and Earth System Simulator (ACCESS) has been adapted for operational and research applications on tropical cyclones. The base system runs at a resolution of 0.11° and 50 levels. The domain ...
