Tornadoes paths mapped12/25/2023 ![]() A growing body of research acknowledges there is a relationship between land surface heterogeneity, which refers to the variations in topography, vegetation, and land cover characteristics that combine to produce different environmental conditions (e.g. To improve forecasting and warning, a better understanding of the relationships between environmental factors and the meteorological processes involved in tornadogenesis is needed (Yuan 2005). In the United States, approximately 1253 tornadoes occur every year (NCDC 2017) causing an average of 50 fatalities and $400 million in annual economic losses (Brooks and Doswell 2001 Boruff et al. Tornadoes are among the most destructive natural hazards to human life and property. Regression results show that several land surface heterogeneity variables have a statistically significant relationship with tornado occurrence, but these relationships vary with region and storm severity, supporting the need for more local studies. Using these relationships uncovered, we map tornado probability across the two regions. ![]() We then use logistic regression to investigate how land heterogeneity factors are related to tornado formation of weakly and significantly tornadic storms. We delineate the spatial extent of Tornado Alley and Dixie Alley based on clusters of tornadic activity. The objective of this study is to uncover the relationships between severe storm occurrence and land surface heterogeneity variables to determine (1) whether certain land heterogeneity variables exhibit a significant relationship with tornado occurrence, and (2) whether those relationships vary by region and storm strength. variations in topography, vegetation, and land cover) and tornado occurrence can provide insight into the spatial distribution of these storms. Examining the relationship between land surface heterogeneity (i.e. In the United States, two regions known as Tornado Alley and Dixie Alley are particularly prone to tornadoes, but determining exactly where tornadoes will occur remains difficult. Tornadoes rank among the most destructive hazards to human life and property.
