Wow. Just when I thought there was a limit to the size of a vortex, Earth does this. The vortex was joined by the jet stream. Holy smokes.
The straight line winds across the southern USA is going to be at least 15 to 20 mph. The heat of the sun will give that wind energy to maintain and increase.
Those winds are occurring across a round Earth. It isn't simply a flat dynamic. Winds that travel across a round Earth already has the potential to make whirls in the sky. Add wind to that native effect of a round Earth and the potential to high velocity winds is possible. Add water vapor and the potential for tornadoes increases. Water vapor is the heat absorption mechanism of Earth. Water vapor is heat energy.
