Multiscale Nested Simulations of Rayleigh–Taylor Instabilities in Ionospheric Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nested numerical simulations of ionospheric plasma density structures associated with nonlinear evolution of the Rayleigh–Taylor (RT) instability in equatorial spread F (ESF) are presented. The numerical implementation ...
Regional Impacts of Irrigation in Mexico and the Southwestern United States on Hydrometeorological Fields in the North American Monsoon Region
Publisher: American Meteorological Society
Abstract: n this study, the impacts of Mexican and southwestern U.S. agricultural and urban irrigation on North American monsoon (NAM) rainfall and other hydrometeorological fields are investigated using the Weather Research and ...
A Numerical Method Based on Leapfrog and a Fourth-Order Implicit Time Filter
Publisher: American Meteorological Society
Abstract: time-stepping scheme is proposed. It is based on the leapfrog method and a fourth-order time filter. The scheme requires only one evaluation per time step and uses an implicit filter, but the effort needed to implement it ...
A Method of Aggregating Heterogeneous Subgrid Land-Cover Input Data for Multiscale Urban Parameterization
Publisher: American Meteorological Society
Abstract: method of representing grid-scale heterogeneous development density for urban climate models from probability density functions of subgrid-resolution observed data is proposed. Derived values are evaluated in relation to ...
Variability of Turbulence and Its Outer Scales in a Model Tropopause Jet
Publisher: American Meteorological Society
Abstract: Variability of flow regimes and turbulence scalings in a model of an inhomogeneously stratified, tropopause jet is investigated through high-resolution, forced, three-dimensional numerical simulations (with 512 or 1024 ...
