  • A Background Investigation of Tornado Activity Across the Southern Cumberland Plateau Terrain System of Northeastern Alabama
    DECEMBER 2018 L Y Z A A N D K N U P P 4261 A Background Investigation of Tornado Activity across the Southern Cumberland Plateau Terrain System of Northeastern Alabama ANTHONY W. LYZA AND KEVIN R. KNUPP Department of Atmospheric Science, Severe Weather Institute–Radar and Lightning Laboratories, Downloaded from http://journals.ametsoc.org/mwr/article-pdf/146/12/4261/4367919/mwr-d-18-0300_1.pdf by NOAA Central Library user on 29 July 2020 University of Alabama in Huntsville, Huntsville, Alabama (Manuscript received 23 August 2018, in final form 5 October 2018) ABSTRACT The effects of terrain on tornadoes are poorly understood. Efforts to understand terrain effects on tornadoes have been limited in scope, typically examining a small number of cases with limited observa- tions or idealized numerical simulations. This study evaluates an apparent tornado activity maximum across the Sand Mountain and Lookout Mountain plateaus of northeastern Alabama. These plateaus, separated by the narrow Wills Valley, span ;5000 km2 and were impacted by 79 tornadoes from 1992 to 2016. This area represents a relative regional statistical maximum in tornadogenesis, with a particular tendency for tornadogenesis on the northwestern side of Sand Mountain. This exploratory paper investigates storm behavior and possible physical explanations for this density of tornadogenesis events and tornadoes. Long-term surface observation datasets indicate that surface winds tend to be stronger and more backed atop Sand Mountain than over the adjacent Tennessee Valley, potentially indicative of changes in the low-level wind profile supportive to storm rotation. The surface data additionally indicate potentially lower lifting condensation levels over the plateaus versus the adjacent valleys, an attribute previously shown to be favorable for tornadogenesis.

Background and Objectives: Treefall patterns and forest damage assessed in post-storm surveys are dependent on the interaction between topography, biology and meteorology, which makes identification of characteristic behavior challenging. Much of our knowledge of tree damage during extreme winds is based on synoptic storms. Better characterization of tree damage will provide more knowledge of tornado impacts on forests, as well as their ecological significance. Materials and Methods: a numerical method based on a Rankine vortex model coupled with two mechanistic tree models for critical wind velocity for stem break and windthrow was used to simulate tornadic tree damage. To calibrate the models, a treefall analysis of the Alonsa tornado was used. Parametric study was conducted to assess induced tornadic tree failure patterns for uprooting on saturated and unsaturated soils and stem break with different knot factors.

  • Damage Analysis of Three Long-Track Tornadoes Using High-Resolution Satellite Imagery
    atmosphere Article Damage Analysis of Three Long-Track Tornadoes Using High-Resolution Satellite Imagery Daniel Burow * , Hannah V. Herrero and Kelsey N. Ellis Department of Geography, University of Tennessee, Knoxville, 1000 Phil Fulmer Way, Knoxville, TN 37920, USA; [email protected] (H.V.H.); [email protected] (K.N.E.) * Correspondence: [email protected] Received: 2 May 2020; Accepted: 8 June 2020; Published: 10 June 2020 Abstract: Remote sensing of tornado damage can provide valuable observations for post-event surveys and reconstructions. The tornadoes of 3 March 2019 in the southeastern United States are an ideal opportunity to relate high-resolution satellite imagery of damage with estimated wind speeds from post-event surveys, as well as with the Rankine vortex tornado wind field model. Of the spectral metrics tested, the strongest correlations with survey-estimated wind speeds are found using a Normalized Difference Vegetation Index (NDVI, used as a proxy for vegetation health) difference image and a principal components analysis emphasizing differences in red and blue band reflectance. NDVI-differenced values across the width of the EF-4 Beauregard-Smiths Station, Alabama, tornado path resemble the pattern of maximum ground-relative wind speeds across the width of the Rankine vortex model. Maximum damage sampled using these techniques occurred within 130 m of the tornado vortex center. The findings presented herein establish the utility of widely accessible Sentinel imagery, which is shown to have sufficient spatial resolution to make inferences about the intensity and dynamics of violent tornadoes occurring in vegetated areas. Keywords: tornadoes; tornado damage; remote sensing; Sentinel-2; NDVI; PCA; Rankine vortex 1.

An Empirical Study Mitchel Stimers* and Bimal Kanti Paul Department of Natural and Physical Sciences, Cloud County Community College, Junction City, Kansas, 66441, USA Abstract The 2011 Joplin, MO, USA, tornado set a record in terms of the number of lives lost-no other tornado in the United States had killed as many as 161 people since 1950. There are many stochastic parameters that can affect the speed, direction, and magnitude of a tornado and it is thought that elevation may play a role in tornado intensity. The Joplin tornado created a track whose elevation was approximately 50 m from beginning to end, providing the impetus to examine whether or not the elevation change over the damage path tornado is associated with fatalities that resulted from the event. Using data collected from various sources, and the application of GIS as well as non-parametric statistics, we reveal that the elevation and tornado fatalities are inversely related, however; the relationship is not statistically significant, the reasons for which are discussed. Keywords: Joplin tornado; Tornado fatalities; Elevation; Damage Dating to 1950, when official tabulation began, no other tornado zone; GIS in the US had killed as many people as the Joplin event.

  • Mesoscale and Stormscale Ingredients of Tornadic Supercells Producing Long-Track Tornadoes in the 2011 Alabama Super Outbreak
    MESOSCALE AND STORMSCALE INGREDIENTS OF TORNADIC SUPERCELLS PRODUCING LONG-TRACK TORNADOES IN THE 2011 ALABAMA SUPER OUTBREAK BY SAMANTHA L. CHIU THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science in Atmospheric Science in the Graduate College of the University of Illinois at Urbana-Champaign, 2013 Urbana, Illinois Advisers: Professor Emeritus Robert B. Wilhelmson Dr. Brian F. Jewett ABSTRACT This study focuses on the environmental and stormscale dynamics of supercells that produce long-track tornadoes, with modeling emphasis on the central Alabama storms from April 27, 2011 - part of the 2011 Super Outbreak. While most of the 204 tornadoes produced on this day were weaker and short-lived, this outbreak produced 5 tornadoes in Alabama alone whose path-length exceeded 50 documented miles. The results of numerical simulations have been inspected for both environmental and stormscale contributions that make possible the formation and maintenance of such long–track tornadoes. A two-pronged approach has been undertaken, utilizing both ideal and case study simulations with the Weather Research and Forecasting [WRF] Model. Ideal simulations are designed to isolate the role of the local storm environment, such as instability and shear, to long-track tornadic storm structure. Properties of simulated soundings, for instance hodograph length and curvature, 0-1km storm relative helicity [SRH], 0-3km SRH and convective available potential energy [CAPE] properties are compared to idealized soundings described by Adlerman and Droegemeier (2005) in an effort to identify properties conducive to storms with non-cycling (sustained) mesocyclones. 200m horizontal grid spacing simulations have been initialized with the 18 UTC Birmingham/Alabaster, Alabama [KBMX] soundings, taken from an area directly hit by the day’s storms.

  • 1 a Review of the Characteristics of Tornadic Wind Fields Through
    A Review of the Characteristics of Tornadic Wind Fields through Observations and Simulations Ryan Honerkampa, Guirong Yanb, and Jeffrey C. Snyderc a Department of Civil, Architectural and Environmental Engineering, Missouri University of Science and Technology, Rolla, MO 65409, [email protected] b Department of Civil, Architectural and Environmental Engineering, Missouri University of Science and Technology, Rolla, MO 65409, [email protected] c NOAA/OAR/National Severe Storms Laboratory, Norman, OK 73072, [email protected] ABSTRACT Tornadoes are violently rotating columns of air that may be produced by convective clouds and storms, and they can produce substantial property damage, injuries, and deaths. To mitigate these losses and encourage accurate modeling and research in the field of civil engineering, with the goal of improving civil structure design, a comprehensive review of field measurements, lab simulations, and computational fluid dynamics (CFD) simulations of tornadoes is conducted. From this review, several tornadoes are examined and their characteristics presented. Specifically, characteristics of these tornadoes are provided in the following form: velocity of the wind field, pressure distribution associated with the wind field, tornado core radius, and flow structure (i.e., single vortex versus multiple vortices; for single vortex, one-celled versus two-celled). In addition, the driving forces behind tornadoes and the relationships between damage and reported intensity are examined, and the physical and numerical simulation of tornadoes conducted in civil engineering are reviewed. This paper is intended to provide a baseline review so that more accurate simulations of tornadic wind fields in civil engineering research can be made by providing some field-measured data from the meteorology community.
