Questions and Answers
Which factor most significantly contributes to the increased vulnerability of the Southeastern United States to tornado-related fatalities?
Which factor most significantly contributes to the increased vulnerability of the Southeastern United States to tornado-related fatalities?
- The lack of advanced warning systems and public shelters in many Southeastern communities.
- The region's higher elevation, which exacerbates wind speeds during tornado events.
- A combination of rural demographics, more frequent nocturnal tornadoes, and dense tree cover. (correct)
- The prevalence of older, poorly constructed homes that are unable to withstand tornado forces.
What is the primary challenge in establishing a direct causal relationship between climate change and the observed increase in tornado activity?
What is the primary challenge in establishing a direct causal relationship between climate change and the observed increase in tornado activity?
- The overwhelming influence of El Niño and La Niña cycles on regional weather patterns.
- The limited availability of supercomputers capable of running high-resolution climate simulations.
- The relatively small scale of tornadoes, which makes it difficult to accurately model the impact of broad climate changes. (correct)
- The lack of historical data on tornado occurrences prior to the advent of modern climate science.
Beyond population growth, what aspect of urban expansion most significantly exacerbates tornado-related damage?
Beyond population growth, what aspect of urban expansion most significantly exacerbates tornado-related damage?
- The increased number of potential targets, meaning more structures and people are in harm's way when a tornado strikes. (correct)
- The decrease in permeable surfaces, leading to increased surface runoff and flooding during storm events.
- The increased density and interconnectedness of infrastructure networks, such as power grids and communication lines.
- The disruption of natural windbreaks, which historically provided protection against high winds.

Study Notes
- A community near Pittsburgh is cleaning up after a rare tornado on Saturday, which downed trees and damaged homes.
- The Great Plains, Midwest, and South experienced a break from severe weather over the weekend.
- April and May are typically the busiest months for tornado activity, but this season has been exceptionally active.
- Tornadoes seem to be impacting more populated areas.
Tornado Devastation
- There has been widespread destruction across the country, from Oklahoma to Iowa to Tennessee.
- Six weeks of storms have created a trail of destruction thousands of miles long.
- There is consideration to whether tornadoes are becoming more common and/or stronger.
Tornado Outbreaks
- There has been an increase in the number of days with 30 or more tornadoes.
- These tornado outbreaks are responsible for 80% of all twister deaths.
- More tornadoes are touching down further east, outside the Great Plains.
- These tornadoes are impacting towns and cities not used to seeing them this often.
- The Southeast has heightened vulnerability with rural areas, more nocturnal tornadoes, and more tree cover.
Climate Change and Tornadoes
- Scientists are hesitant to make a direct link between climate change and tornado activity.
- Tornadoes are too small to accurately model the effect of climate change.
- A warming climate provides the fuel for supercell storms, the massive systems that can spin off twisters.
- There is an expectation of more events fueled by heat and moisture at the surface in the next 30-40 years.
Adapting to Shifting Storm Patterns
- Humans need to adjust as storm patterns continue to shift.
- As cities grow and expand, there are more targets for tornadoes to hit.
- How we build is just as important as how strong the tornado is.
Unusual Tornado Activity in 2024
- There have been more than 6,000 reports of large hail, damaging winds, and tornadoes since the start of the year.
- Over 260 twisters have impacted 19 states in the last few weeks.
- April was the second most active April in terms of tornadoes, behind 2011.
- There have already been two violent EF-4 tornadoes in Oklahoma, the strongest to strike the state in eight years.
- There is possibility of more strong storms from Texas to Mississippi.
