Why do some places experience tornadoes and others don't?

Answer 1

It is actually hard to find a places that doesn't get tornadoes. Most places do have them, but strong ones are very rare in most places. Tornadoes need the right setup of weather conditions to form, and differences in climate from one region to the next will affect how often these conditions come together, and how ideal they are. Conditions that create an ideal setup for a major tornado outbreak include:

• Atmospheric instability
• Strong wind shear
• A strong jet stream
• High helicity or twisting of air currents
• A cold front or dry line to trigger thunderstorms
• High relative humidity
• A cap of stable air to allow instability to build

Answer 2

Tornadoes are mainly caused by specific weather conditions, including warm, moist air meeting cool, dry air. Areas that have these conditions are more likely to experience tornadoes. Geographical features like mountains or bodies of water can also affect tornado formation and make some areas more prone to tornadoes than others.
