Definiing Tornado Alley ands Geographic Boundaries

Tornado Alley is not a formally mapped political boundary but a consensus term used by by meteorologs, climate scients, and emergency managers to description the region of thee central United States with the highest frequency of strong to violent tornadoes.

Warm, moist air frem the Mexico streams northward, while cool, dry air descoudds from the Rocky Mountains.

A third condiment - strong wind shear aid varying althunderstorms - completes the recipe for rotionale storm development.

However, the boundaries of Tornado Alley are debate. Some research chers argue for a wideler definition that extends into thee Upper Midwest and even thee Western portions of thee Ohio Valley.
