WRF Model Sensitivity to Choice of Parameterization over South America: validation against surface variables
(American Meteorological Society, 2010-08)
The Weather and Research Forecast model is tested over South America in different configurations to identify the one that gives the best estimates of observed surface variables. Systematic, nonsystematic, and total errors ...
Análisis de re-simulaciones de regiones subdensas de la estructura en gran escala del Universo
(2020-07)
Se identificaron vacíos cosmológicos en una simulación de materia oscura. Se seleccionaron 2 en base a su clasificación dinámica ( tipos R y tipo S ) y fueron resimulados introduciendo física bariónica mediante modelos ...
Three regularization models of the Navier-Stokes equations
(American Institute of Physics, 2008-03)
We determine how the differences in the treatment of the subfilter-scale physics affect the properties of the flow for three closely related regularizations of Navier-Stokes. The consequences on the applicability of the ...
Numerical simulation of the flow around the ahmed vehicle model
(Planta Piloto de Ingeniería Química, 2009-10)
The unsteady flow around the Ahmed vehicle model is numerically solved for a Reynolds number of 4.25 million based on the model length. A viscous and incompressible fluid flow of Newtonian type governed by the Navier-Stokes ...
WRF sensibility to microphysics and planetary boundary layer at micro-catchment scale: the case of the Quinuas catchment in the tropical andes of Ecuador
(2018-03-29)
Reliable high-resolution forecasts of precipitation are necessary to improve hydrological models forecasting. This is important in mountain regions, where complex convective and orographic processes occur. The present study ...
The Coupled Aerosol and Tracer Transport model to the Brazilian developments on the Regional Atmospheric Modeling System (CATT-BRAMS) - Part 1: Model description and evaluation
(COPERNICUS PUBLICATIONS, 2009)
We introduce the Coupled Aerosol and Tracer Transport model to the Brazilian developments on the Regional Atmospheric Modeling System (CATT-BRAMS). CATT-BRAMS is an on-line transport model fully consistent with the simulated ...
Inverse cascades and α effect at a low magnetic Prandtl number
(American Physical Society, 2007-12)
Dynamo action in a fully helical Arn'old-Beltrami-Childress flow is studied using both direct numerical simulations and subgrid modeling. Sufficient scale separation is given in order to allow for large-scale magnetic ...
Spectral modeling of rotating turbulent flows
(American Institute of Physics, 2010-02)
A subgrid-scale spectral model of rotating turbulent flows is tested against direct numerical simulations (DNSs). The case of Taylor-Green forcing is considered, a configuration that mimics the flow between two counter-rotating ...
Numerical Simulations of the Flow Around a Spinning Projectile in Subsonic Regime
(Planta Piloto de Ingeniería Química, 2008-12)
The unsteady flow around a 155 mm projectile governed by the Navier-Stokes (NS) equations is numerically solved with a Large Eddy Simulation (LES) scheme, together with the SubGrid Scale (SGS) solved by a Smagorinsky model ...
Seasonal Variability of the Southern Tip of the Oxygen Minimum Zone in the Eastern South Pacific (30 degrees-38 degrees S): A Modeling Study
(2019)
We investigate the seasonal variability of the southern tip (30 degrees-38 degrees S) of the eastern South Pacific oxygen minimum zone (OMZ) based on a high horizontal resolution (1/12 degrees) regional coupled ...
