Using High-Resolution Simulations to Quantify Errors in Radar Estimates of Tornado Intensity
Publisher: American Meteorological Society
Abstract: AbstractObservation experiments are performed on a set of high-resolution large-eddy simulations of translating tornado-like vortices. Near-surface Doppler wind measurements are taken by emulating a mobile radar positioned ...
Axisymmetric Tornado Simulations at High Reynolds Number
Publisher: American Meteorological Society
Abstract: his study is the first in a series that investigates the effects of turbulence in the boundary layer of a tornado vortex. In this part, axisymmetric simulations with constant viscosity are used to explore the relationships ...
Tornado Vortex Structure, Intensity, and Surface Wind Gusts in Large-Eddy Simulations with Fully Developed Turbulence
Publisher: American Meteorological Society
Abstract: large-eddy simulation (LES) framework with an ?eddy injection? technique has been developed that ensures a majority of turbulent kinetic energy in numerically simulated tornado-like vortices is represented by resolved ...
Using High-Resolution Simulations to Quantify Underestimates of Tornado Intensity from In Situ Observations
Publisher: American Meteorological Society
Abstract: arge-eddy simulations are used to produce realistic, high-resolution depictions of near-surface winds in translating tornadoes. The translation speed, swirl ratio, and vertical forcing are varied to provide a range of ...
An Eddy Injection Method for Large-Eddy Simulations of Tornado-Like Vortices
Publisher: American Meteorological Society
Abstract: he structure and intensity of tornado-like vortices are examined using large-eddy simulations (LES) in an idealized framework. The analysis focuses on whether the simulated boundary layer contains resolved turbulent eddies, ...
Spatially variable advection correction of Doppler radial velocity data
Publisher: American Meteorological Society
Abstract: Techniques to mitigate analysis errors arising from the non-simultaneity of data collections typically use advection-correction procedures based on the hypothesis (frozen turbulence) that the analyzed field can be represented ...
High-Resolution, Rapid-Scan Dual-Doppler Retrievals of Vertical Velocity in a Simulated Supercell
Publisher: American Meteorological Society
Abstract: AbstractObservation system simulation experiments are used to evaluate different dual-Doppler analysis (DDA) methods for retrieving vertical velocity w at grid spacings on the order of 100 m within a simulated tornadic ...
