What Makes a Tornado


Time for tornado talk!! Before we get into the where and why, let’s start with the how! 

The wind on the surface of the earth and the wind a couple thousand feet up are normally blowing in opposite directions do to the friction of the earth’s surface. Because the winds are blowing at each other it forms a horizontal vortex to form in the atmosphere. 

When a thunderstorm forms, an updraft forms within it. The updraft now begins to rotate the horizontal vortex or tube into a vertical position. The stronger the updraft the faster the spinning gets. As the clouds begin to spin a funnel cloud forms. A funnel cloud becomes a tornado only when it reaches the ground.
