How does the earths shape and rotation help to create hurricanes and tornadoes?
A rotational dynamic is then created in the atmosphere (think of the earth as the spoon). Atmosphere (air) is then pushed by these forces, causing rotational turbulence, which often contacts the ground surface, resulting in hurricanes and tornados. The prediction of outcome is impossible to know, outside of established and documented weather patterns. Think of yourself as a bug in a blender.
