In the United States, which region has the greatest frequency of tornadoes?

• A. Midwest
• B. Northeast
• C. Southeast
• D. West

Answer: (A)

Tornado frequency is highest in the central United States, where warm, moist air from the Gulf of Mexico meets cool, dry air from the north and west, creating strong wind shear that helps storms rotate. The flat plains of the Midwest allow these powerful supercell thunderstorms to form and persist, leading to many tornado events each year. This area is often called Tornado Alley, and it overlaps the Midwest region, making it the region with the greatest number of tornadoes. The Northeast and West are drier or less favorable for sustained rotating storms, and while the Southeast experiences many tornadoes, their overall frequency is lower than in the central Midwest.
