identify the steps that change wind shear into a tornado
When wind shear occurs, air moves at different speeds, heights, and directions. This can eventually lead to the formation of a mesocyclone. A mesocyclone is a rotation column of air, starting at horizontal, but becoming vertical when a powerful updraft knocks it vertical. If a RFD is present, it will rotate downward hugging the surface of the mesocyclone, funneling a smaller and smaller point as it reaches the bottom. This is like a skater pulling in her arms, leading to faster rotation. The same is true for tornadoes. If a powerful updraft creates a low pressure area near the surface, the combination of RFD pushing downward and low pressure area near the surface, drawing the funnel downward, could eventually lead to a complete tornado.
