Using GIS to assess vulnerability to climate hazards in the southern United States
A geographic information system (GIS) is used to assess the vulnerability of the southern United States to several meteorological hazards. The study focuses on the region covered by the Southern Climate Impacts Planning Program (SCIPP), a part of the Regional Integrated Sciences and Assessments (RISA) program. The SCIPP region includes Arkansas, Louisiana, Mississippi, Oklahoma, Tennessee, and Texas. There are significant differences between two subregions of the study area. One subregion contains Oklahoma and Texas, while the other contains Arkansas, Louisiana, Mississippi, and Tennessee. While Oklahoma and Texas are exposed to more hazards (especially tornadoes), the impacts of these events are greater in the eastern region.
