For a tornado to form there must be a cold front, and low-level moisture. Tornadoes are associated with big and strong thunderstorms. A column of warm and humid air will rise quickly. How it begins to rotate is not understood by scientists, but what they think is that two different winds with different altitudes and speeds. This creates a wind shear. The column of air sometimes gets caught in a super cell updraft. The updraft will tighten and speed up. When it begins to rain and hail, the precipitation will push down the column of air to create a tornado.

The positive and negative charges attract each other and the charges will grow strong enough to overcome the air's resistance to electrical flow. Then the charges race toward each other, they connect, and create an electrical circuit. Then it discharges the accumulated electricity as lightning. Lightning will most likely occur in the summer time during a thunderstorm. As the lightning strikes, it travels downward toward the ground. Lightning is measured by how much electricity a bolt of lightning will contain. What you should do during a lightning storm is try to stay indoors. Be sure to avoid water.
