Tornado Trouble: How Can Current Tornado Warnings be Improved?
<p>There are many unnecessary deaths from tornadoes every year (NOAA.org, 2013). Although there have been great advancements in tornado warning systems (Coleman, Knupp, Spann, Elliot, & Peters, 2010), more changes to systems could be made to motivate people to take action in preparation for …

Retrofitting unreinforced concrete masonry to resist tornado loading
… structural failure after extreme wind events and tornadoes remains a problem which costs the insurance industry billions of dollars and results in an average loss of 200 lives per year in the United States. Accountable for many of these structural failures, buildings with walls of Unreinforced …

Insights into tornadogenesis and tornado dynamics from idealized simulations
… in a robust understanding of many aspects of tornadoes, such as the environmental conditions necessary for storms with tornado potential and the complex dynamics of mature tornadoes. However, the detailed processes during tornadogenesis are still less understood. One reason for this might be …

Hazard Perception Research: A Critique and Proposal (Fishbein, Tornado)
Hazard perception research has been based on the assumption that an individual's hazard behavior is a function of his hazard perception (his subjective beliefs about the hazard). Yet empirical evidence on the perception-behavior relationship has been contradictory. Further, the behavioral impacts …

Near-surface tornado wind field estimation using damage patterns
Tornadoes are considered the most violent and dangerous wind hazards and are emerging as a major public concern, causing a significant amount of property loss and casualties in the past decades. In response, the engineering community in the United States is implementing tornado-based design in …

Calculation of wind borne debris impact in tornado event
In strong wind events like tornado and hurricane, significant destruction is caused to buildings due to wind-borne debris, which are usually damaged structural members and components with insufficient attachment. This debris, also referred to as missiles, can penetrate building walls and roofs and …

Spatial Patterns and Variations of Tornado Damage as Related to Southeastern Appalachian Forests and Terrain from the Franklin County, Virginia EF-3 Tornado
Strong tornadoes have impacted the central Appalachian Mountains multiple times in recent years. The topography of this region leads to unique spatial patterns of tornado damage as the tornado vortices pass over ridges in forested areas, and this damage can be detected with vegetation indices …

Effects of wind turbine rotor positioning on tornado induced loads
… investigates the loads induced by a large-scale tornado simulation on a horizontal axis wind turbine (HAWT) to assess the influence of three-dimensional flows with respect to the HAWT position. The loads were analyzed under two rotor operational conditions, idling and parked, at five radial …

Large -eddy simulation of a three-dimensional compressible tornado vortex
… has become a very useful tool for investigating tornadoes, one of the more spectacular and destructive phenomena of nature. A new three-dimensional, unsteady, compressible model is generated to determine how significant the differences between compressible and incompressible LES simulations may …

Understanding tornado intensity in supercells and quasi-linear convective systems
… storms capable of producing strong to violent tornadoes remains a focus of severe weather research due to their potentially significant impacts on life and property. The three parts of this dissertation contribute to new understanding of the controls on, and operational anticipation of, such …

Behavior of Wind Turbine Towers and Blades Under Tornado Wind Fields
… high-intensity wind (HIW) events such as tornadoes. The built-in-house numerical code “HIW-WT” has been developed in this study to model wind turbines under three-dimensional wind fields such as tornadoes. Extensive analysis has been conducted with the goal of determining the critical …
