Contrary to popular belief, it is not the flat land that helps tornadoes form. The are often sees a collision of warm, moist air with cooler and/or drier air. This produces thunderstorms. Wind shear, which is a change in the speed and/or direction of wind with altitude, tilts the storms, which helps them become stronger. It also gives them the rotation they need to produce tornadoes. Finally the central U.S. often has a strong cap, which is a layer of stable air a few thousand feet above the ground. This cap holds back storm development and allows instability to build under it. Eventually the storms may break the cap and when they do they will develop explosively.
No other place in the world sees such ideal conditions for tornadoes so often.
