Which region of the United States is nicknamed “Tornado Alley”?

Midwest

"Tornado Alley" in the Midwest of the United States is notorious for its high frequency of tornadoes, due to the meeting of cold, dry air from Canada with warm, moist air from the Gulf of Mexico. This region includes states such as Oklahoma, Kansas, and Texas. Advanced research and technologies, like Doppler radars, are crucial for protecting communities in this high-risk area. Understanding these phenomena allows for better preparation and response to tornadoes, thus minimizing their devastating impact.
