Which region is most associated with frequent tornado activity?

Which region is most associated with frequent tornado activity?

• A. Southeast Asia
• B. Northern Europe
• C. United States Great Plains
• D. Sub-Saharan Africa

Answer: (C)

The region in the central United States is where warm, moist air from the Gulf of Mexico meets cool, dry air from the north, and the jet stream aloft winds overhead. That clash creates powerful, rotating thunderstorms that can develop into tornadoes. The flat, open plains let these storms organize and persist, especially in spring, producing frequent tornado outbreaks. Other areas don’t typically experience this same combination of air masses, wind shear, and storm organization: Southeast Asia is dominated by tropical systems, Northern Europe has a cooler, maritime climate with less frequent convective storms, and Sub-Saharan Africa’s weather patterns don’t regularly support the same high-frequency tornado activity.
