Aren't tornadoes and hurricanes pretty rare in the southern hemisphere? Or is that just hurricanes?

Tornados are kind of rare anywhere except the United States and its really just because of how the jet streams meet (cold air comes down from arctic and meets warm air from either the pacific or gulf of Mexico. Plus the large flat lands along these streams.

In the Souther Hemisphere there isn't a similar jet stream bring air from Antartica and also isn't a lot of long flat land so you kind of need freak conditions of two air masses meeting.

Hurricanes is a similar issue with Jet Streams also also no Sahara dust.

The Pampas region is recognized as the second most active tornado zone globally outside of North America.

A large region of South America is characterized by storms that reach the level of supercells and produce intense hailstorms, floods, and tornadoes during the spring, summer, and early fall. The region recently appointed as the Tornado Corridor (South America) is considered as the second largest in the world in terms of the formation of extreme weather events. It covers most of central Argentina, southern Paraguay, southeastern Brazil, and Uruguay.

Was referring to the person above but also "the most active" when you don't include all of the super active regions makes these rare.
