Localized Artificial Viscosity Stabilization of Discontinuous Galerkin Methods for Nonhydrostatic Mesoscale Atmospheric Modeling
Publisher: American Meteorological Society
Abstract: ibbs oscillation can show up near flow regions with strong temperature gradients in the numerical simulation of nonhydrostatic mesoscale atmospheric flows when using the high-order discontinuous Galerkin (DG) method. The ...
A Comparison of Adaptive Observing Guidance for Atlantic Tropical Cyclones
Publisher: American Meteorological Society
Abstract: Airborne adaptive observations have been collected for more than two decades in the neighborhood of tropical cyclones, to attempt to improve short-range forecasts of cyclone track. However, only simple subjective strategies ...
Interpretation of Adaptive Observing Guidance for Atlantic Tropical Cyclones
Publisher: American Meteorological Society
Abstract: Adaptive observing guidance products for Atlantic tropical cyclones are compared using composite techniques that allow one to quantitatively examine differences in the spatial structures of the guidance maps and relate ...
Measuring Storm Surge with an Airborne Wide-Swath Radar Altimeter
Publisher: American Meteorological Society
Abstract: Over the years, hurricane track forecasts and storm surge models, as well the digital terrain and bathymetry data they depend on, have improved significantly. Strides have also been made in the knowledge of the detailed ...
