Tornadoes Can Occur on Every Continent Except Antarctica

The specific atmospheric conditions needed to spawn a tornado, while most common in the central United States, are not unique to that region. Tornadoes are born from the immense energy of severe thunderstorms, which form when warm, moist air is forced to rise rapidly beneath a layer of cooler, drier air. A change in wind speed and direction with height, known as wind shear, creates a horizontal spinning effect in the lower atmosphere. This rotating column of air can then be tilted vertically by the storm's updraft, forming the powerful vortex of a tornado if it connects with the ground.

These volatile conditions can be found across the globe. The plains of Bangladesh, for instance, experience some of the world's most severe tornadoes, fueled by cold, dry air from the Himalayas meeting warm, moist air from the Bay of Bengal. This region holds the tragic record for the deadliest tornado in history, the 1989 Daulatpur–Saturia tornado, which claimed an estimated 1,300 lives. Similarly, a "tornado corridor" exists in South America, covering parts of Argentina, where cold air from the south frequently collides with warm, tropical air. South Africa also experiences regular tornado activity, particularly during its summer months.

The single exception to this global phenomenon is Antarctica. The continent's consistently frigid temperatures and lack of warm, humid air masses make the development of the powerful thunderstorms necessary for tornado formation impossible. Its polar climate is simply too cold and stable to generate the atmospheric instability that fuels these destructive storms, leaving it as the only continent safe from their wrath.
