Question

what causes tornadoes to form and why are they so often along the same historical paths?

In: Physics

Answer 1

As to why they follow the same paths:

Geography largely defines weather patterns. Since the actual geography of the Great Plains remains the same, the cold weather comes down to the same relative place and meet warm air masses in the same relative places and so the storms form in the same relative places.
