Response Functions for Arbitrary Weight Functions and Data Distributions. Part I: Framework for Interpreting the Response Function
Publisher: American Meteorological Society
Abstract: The response function is a commonly used measure of analysis scheme properties. Its use in the interpretation of analyses of real-valued data, however, is unnecessarily complicated by the structure of the standard form of ...
Vertical Variations of Boundary Layer Potential Buoyancy in Tornadic and Nontornadic Near-Storm Environments
Publisher: American Meteorological Society
Abstract: espite great strides in understanding the tornadic near-storm environment (NSE), at times it remains difficult to determine why some storms produce significant tornadoes, while others produce none, given similar pretornadic ...
An Adaptation of the Barnes Filter Applied to the Objective Analysis of Radar Data
Publisher: American Meteorological Society
Abstract: Spatial objective analysis is routinely performed in several applications that utilize radar data. Because of their relative simplicity and computational efficiency, one-pass distance-dependent weighted-average (DDWA) ...
Response Functions for Arbitrary Weight Functions and Data Distributions. Part II: Response Function Derivation and Verification
Publisher: American Meteorological Society
Abstract: Distance-dependent weighted averaging (DDWA) is a process that is fundamental to most of the objective analysis schemes that are used in meteorology. Despite its ubiquity, aspects of its effects are still poorly understood. ...
Influence of Low-Level Thermodynamic Structure on the Downdraft Properties of Simulated Supercells
Publisher: American Meteorological Society
Abstract: dealized simulations using the Weather Research and Forecasting Model (WRF) were performed to examine the role of capping inversions on the near-surface thermodynamic structure of outflow from simulated supercells. Two ...
Ray Curvature on a Flat Earth for Computing Virtual WSR-88D Signatures of Simulated Supercell Storms
Publisher: American Meteorological Society
Abstract: AbstractTwo accepted postulates for applications of ground-based weather radars are that Earth?s surface is a perfect sphere and that all the rays launched at low-elevation angles have the same constant small curvature. ...
Choosing the Smoothing Parameters within a Multiple-Pass Barnes Objective Analysis Scheme: A Cautionary Note
Publisher: American Meteorological Society
Abstract: Various combinations of smoothing parameters within a two-pass Barnes objective analysis scheme are applied to analytic observations obtained by regular and irregular sampling of a one-dimensional sinusoidal analytic wave ...
Practical Considerations with Radar Data Height and Great Circle Distance Determination
Publisher: American Meteorological Society
