Geography Explains U.S. Tornado Dominance

The United States experiences far more tornadoes because of a unique geographic setup: cold, dry air from Canada or the Rockies collides with warm, humid Gulf air over vast, flat plains, producing frequent supercell thunderstorms. That high baseline is amplified by dense monitoring and population exposure, while climate change appears to be shifting seasonality earlier and increasing storm intensity. — Understanding this mix of physical geography, monitoring bias, and climate-driven change matters for where to invest in warning systems, building codes, and public-health planning.
