A Variational Technique for Dealiasing Doppler Radial Velocity Data
Publisher: American Meteorological Society
Abstract: Velocity folding, or aliasing, is one of most significant impediments to the use of radial winds from Doppler weather radar. In this note, a variational algorithm is developed in which dealiasing is performed using wind ...
NEXRAD and the Broadcast Weather Industry: Preparing to Share the Technology
Publisher: American Meteorological Society
Abstract: This paper describes results from a survey designed to establish the current level of radar and computer technology of the television weather industry, and to assess the awareness and attitudes of television weather ...
A Theoretical and Numerical Study of Density Currents in Nonconstant Shear Flows
Publisher: American Meteorological Society
Abstract: The previous idealized two-fluid model of a density current in constant shear is extended to the case where the inflow shear is confined to the low levels. The analytical solution is determined by the conservation of mass, ...
Dynamic Adjustment in a Numerically Simulated Mesoscale Convective System: Impact of the Velocity Field
Publisher: American Meteorological Society
Abstract: An identical twin methodology is applied to a three-dimensional cloud model to study the dynamics of adjustment in deep convective storms. The principal goal is to diagnose how mass and velocity fields mutually adjust in ...
Validity of the Tangent Linear Approximation in a Moist Convective Cloud Model
Publisher: American Meteorological Society
Abstract: The validity of the moist tangent linear model (TLM) derived from a time-dependent 1D Eulerian cloud model is investigated by comparing TLM solutions to differences between results from a nonlinear model identically ...
Sensitivity Analysis of a Moist 1D Eulerian Cloud Model Using Automatic Differentiation
Publisher: American Meteorological Society
Abstract: An automatic differentiation tool (ADIFOR) is applied to a warm-rain, time-dependent 1D cloud model to study the influence of input parameter variability, including that associated with the initial state as well as physical ...
The Sensitivity of Numerically Simulated Cyclic Mesocyclogenesis to Variations in Model Physical and Computational Parameters
Publisher: American Meteorological Society
Abstract: In a previous paper, a three-dimensional numerical model was used to study the evolution of successive mesocyclones produced by a single supercell storm, that is, cyclic mesocyclogenesis. Not all supercells, simulated or ...
The Dependence of Numerically Simulated Cyclic Mesocyclogenesis upon Environmental Vertical Wind Shear
Publisher: American Meteorological Society
Abstract: Building upon the authors? previous work that examined the dynamics of numerically simulated cyclic mesocyclogenesis and its dependence upon model physical and computational parameters, this study likewise uses idealized ...
Three-Dimensional Numerical Modeling of Convection Produced by Interacting Thunderstorm Outflows. Part II: Variations in Vertical Wind Shear
Publisher: American Meteorological Society
Abstract: In this second paper in a series on outflow interactions, we use the three-dimensional model described in Part I to examine the effects of vertical wind shear variations on cloud development along intersecting thunderstorm ...
