RISA Comparison of Right-Moving Supercell and Quasi-Linear Convective System Tornadoes in the Contiguous United States 2003–21
Publisher: American Meteorological Society
Eta Model Storm-Relative Winds Associated with Tornadic and Nontornadic Supercells
Publisher: American Meteorological Society
Abstract: A conceptual model for sustained low-level mesocyclones is tested as a tornado forecast tool with observations and forecasts from the operational Eta Model. In the conceptual model, a balance between low-level storm inflow ...
Right-Moving Supercell Tornadogenesis during Interaction with a Left-Moving Supercell’s Rear-Flank Outflow
Publisher: American Meteorological Society
Nationwide Comparisons of Hail Size with WSR-88D Vertically Integrated Liquid Water and Derived Thermodynamic Sounding Data
Publisher: American Meteorological Society
Abstract: This study tests hypothetical correspondences between size of severe hail, WSR-88D derived vertically integrated liquid water (VIL), and an array of thermodynamic variables derived from computationally modified sounding ...
An Overview of Environmental Conditions and Forecast Implications of the 3 May 1999 Tornado Outbreak
Publisher: American Meteorological Society
Abstract: An overview of conditions associated with the Oklahoma?Kansas tornado outbreak of 3 May 1999 is presented, with emphasis on the evolution of environmental and supercellular characteristics most relevant to the prediction ...
Comments on “The North Dakota Tornadic Supercells of 18 July 2004: Issues Concerning High LCL Heights and Evapotranspiration”
Publisher: American Meteorological Society
FORECASTER’S FORUM: Subjective Tornado Probability Forecasts in Severe Weather Watches
Publisher: American Meteorological Society
Abstract: An experiment was conducted at the Storm Prediction Center (SPC) to assess the accuracy of subjective probability forecasts for tornadoes within individual convective watch areas. Probability forecasts for one or more and ...
A Comprehensive Analysis of the Spatial and Seasonal Shifts in Tornado Activity in the United States

Effective Storm-Relative Helicity and Bulk Shear in Supercell Thunderstorm Environments
Publisher: American Meteorological Society
Abstract: A sample of 1185 Rapid Update Cycle (RUC) model analysis (0 h) proximity soundings, within 40 km and 30 min of radar-identified discrete storms, was categorized by several storm types: significantly tornadic supercells (F2 ...
The Optimal Bulk Wind Differential Depth and the Utility of the Upper-Tropospheric Storm-Relative Flow for Forecasting Supercells
Publisher: American Meteorological Society
Abstract: An analysis of 4 yr of Rapid Update Cycle-2 (RUC-2) derived soundings in proximity to radar-observed supercells and nonsupercells is conducted in an effort to answer two questions: 1) over what depth is the fixed-layer ...
