An Assessment of Supercell and Tornado Forecast Parameters with RUC-2 Model Close Proximity Soundings
In a preliminary investigation, Edwards and Thompson (2000; hereafter ET00) examined multiple sounding parameters related to supercell and tornado potential with a sample of 188 close proximity soundings derived from RUC-2 model hourly analyses. Building upon that initial work, we have expanded our sample to include 548 close proximity soundings associated with supercells, and a smaller set (75...
متن کاملClose Proximity Soundings within Supercell Environments Obtained from the Rapid Update Cycle
A sample of 413 soundings in close proximity to tornadic and nontornadic supercells is examined. The soundings were obtained from hourly analyses generated by the 40-km Rapid Update Cycle-2 (RUC-2) analysis and forecast system. A comparison of 149 observed soundings and collocated RUC-2 soundings in regional supercell environments reveals that the RUC-2 model analyses were reasonably accurate t...
متن کاملNOTES AND CORRESPONDENCE Refined Supercell and Tornado Forecast Parameters
This note updates a previous study that utilized a baseline climatology of soundings associated with large hail, significant tornadoes, and 10 or more cloud-to-ground lightning flashes from 1992. Expanding on the earlier analysis, it is shown that three modified forecast parameters have more value in distinguishing between environments that favor significant tornadoes and those that favor large...

متن کاملA Baseline Climatology of Sounding-Derived Supercell and Tornado Forecast Parameters
All of the 0000 UTC soundings from the United States made during the year 1992 that have nonzero convective available potential energy (CAPE) are examined. Soundings are classified as being associated with nonsupercell thunderstorms, supercells without significant tornadoes, and supercells with significant tornadoes. This classification is made by attempting to pair, based on the low-level soun...
