Summary of "Tornadoes 101 | National Geographic"
Scientific Concepts and Phenomena
- Tornado Formation: Tornadoes are powerful spinning columns of air that form from the interaction of high and low-pressure air.
- Types of Tornadoes:
- Supercell Tornadoes: Form within supercell thunderstorms and are the most violent.
- Non-Supercell Tornadoes: Smaller and weaker, including waterspouts and landspouts.
- Air Pressure Dynamics: The movement of air particles from high-pressure areas to low-pressure areas creates wind, which can lead to Tornado Formation.
- Updrafts: An upward current of wind is essential for tornado development, stretching the vortex until it reaches the clouds.
- Enhanced Fujita Scale: A classification system for tornadoes ranging from EF0 (weakest) to EF5 (strongest), based on damage and wind speed estimates.
Methodology for Tornado Prediction
- Meteorologists monitor storm fronts in high-risk areas.
- Forecasting efforts aim to predict tornadic events to mitigate damage and save lives.
Notable Discoveries
- The United States has the highest number of tornadoes, averaging over 1,000 annually.
- The strongest recorded tornado occurred in Oklahoma City in 1999, classified as EF5 with wind speeds over 300 mph, resulting in significant fatalities and damages.
