Study Notes
Tornado Activity in the US
- Tornadoes are common in the US year-round, peaking from March to July.
- "Tornado Alley" (Texas, Oklahoma, Kansas, Nebraska, South Dakota, Indiana, Missouri, Iowa, and Ohio) is most vulnerable.
- April 2024 saw over 300 tornadoes nationwide, exceeding the average of 182.
- A significant outbreak struck from April 25-28, 2024, with concentrated activity in multiple states.
- Marietta, Oklahoma, experienced an EF-4 tornado on April 27, 2024, causing fatalities and extensive damage, including a hospital and nursing home.
- Minden, Iowa, was severely impacted by a powerful tornado on April 26, 2024, destroying and damaging numerous homes.
- May 2024 also saw high tornado activity, focused around Oklahoma, Michigan, and Tennessee, with some extending as far south as Florida (Tallahassee experienced multiple tornadoes on May 10).
- While current activity is high, it is not yet comparable to the record high of 1,287 tornadoes in 2011.
Tornado Formation and Characteristics
- Tornadoes are violently rotating columns of air from severe thunderstorm clouds to the ground.
- Supercell thunderstorms (intense rotating storms) are necessary for tornado formation.
- Supercells form when the combination of cold dry polar air meets warm, moist tropical air.
- The rising warm air and surrounding winds induce rotation, creating a funnel and a low-pressure area inside the funnel, which sucks in air and objects.
- Supercells can persist for hours, unlike typical thunderstorms (30-60 minutes).
Geographic Factors & Impact
- The US encounters about 1,200 tornadoes annually, the most globally.
- "Tornado Alley's" geography leads to high tornado frequency due to the converging air masses (dry from Rocky Mountains, warm/humid from Gulf of Mexico, and cold from the north).
- Tornadoes have significant destructive power, causing property damage, injuries, and casualties.
