| Abstract: | Most U.S. metropolitan regions have experienced urban “sprawl,” or the outward spreading of urban development from city centers.
For cities lying in areas prone to severe weather, the sprawl phenomenon exposes greater numbers of developed areas and inhabitants
to a variety of thunderstorm hazards. This study’s principal goal is to determine how urbanization growth patterns affect
a region’s vulnerability to severe weather events. To assess how sprawl may impact vulnerability to tornadoes, hail, and convective
wind events, an analysis examining potential loss may be utilized. This study employs two distinct approaches to examine how
the Atlanta area’s rapid and extensive development during the latter half of the twentieth Century has affected its overall
potential exposure to thunderstorm hazards. First, archived census data are used to estimate overall impacts from hypothetical
significant tornado, nontornadic convective wind, and hail events occurring at different time periods throughout several locations
in the Atlanta metropolitan region. Second, economic factors are integrated into the analysis, which assists in determining
how these hypothetical severe event scenarios may have changed from a cost standpoint if they were to occur in 2006 as opposed
to 1960. |
