Study Notes
- The 2024 US tornado season is on track to be one of the most active in history.
- Tornadoes are most active from March to July in the United States.
- Tornado Alley is the region most susceptible to tornadoes.
- Tornado Alley includes parts of Texas, Oklahoma, Kansas, Nebraska, South Dakota, Indiana, Missouri, Iowa, and Ohio.
- Tornado activity typically increases in April, averaging about 182 tornadoes.
- In April 2024, over 300 tornadoes were reported across the US.
- From April 25-28, 2024, about 100 tornadoes occurred.
- During the April 25-28 outbreak, Oklahoma had 30 tornadoes, Iowa had at least 24, Texas had 20, Missouri had 16, Kansas had 15, and Nebraska had 13.
Impacted Areas
- Marietta, Oklahoma, was hit by an EF-4 tornado on April 27, 2024, with winds between 166 mph and 200 mph.
- The tornado in Marietta, Oklahoma, killed one person and destroyed several structures, including a hospital and a nursing home.
- Minden, Iowa, suffered significant damage from a tornado on April 26, 2024, which destroyed 48 homes and damaged over 300 structures.
- As of May 12, 2024, at least 133 tornadoes have been reported.
- Most of the May tornadoes have been clustered around Oklahoma, Michigan, and Tennessee.
- On May 10, 2024, Tallahassee, Florida, was struck by three tornadoes, which damaged buildings and downed trees and utility poles.
Statistics
- As of May 13, 2024, thousands of residents in Tallahassee, Florida remained without power.
- In 2011, 1,287 tornadoes had struck the US by May 7, marking a record tornado season.
Tornado Formation
- A tornado is a rotating column of air extending from a thunderstorm cloud to the ground.
- Tornadoes form during severe rotating storms called supercells.
- Supercells occur when cold, dry polar air meets warm, moist tropical air.
- As warm air rises, storm winds cause rotation and funnel formation.
- The spinning funnel creates a low-pressure area, sucking in more air and objects.
- Ordinary thunderstorms last 30-60 minutes, while supercells can last for hours.
- The US experiences the most tornadoes, with about 1,200 annually.
Tornado Alley
- Tornado Alley's geography makes it prone to tornadoes.
- Dry air from the Rocky Mountains meets warm, humid air from the Gulf of Mexico and cold Arctic air from the north.
- This combination creates conditions for powerful storms that often become deadly tornadoes.
