The United States has more tornadoes （龙卷风） than any other country in the world. In a normal year， there are 800 to 1，000 tornadoes. Most happen in the middle part of the country. Tornadoes form when warm and cool air meet. In the Midwest， the warm air from the Gulf of Mexico often meets the cold air from Canada.

The usual tornado season is March through May. Tornadoes form most often in the afternoon and early evening. There is often no warning of a tornado. People who live in the Midwest know the signs of tornado activity. The sky becomes dark， often a greenish color. Dark clouds appear in the sky and there is often large hail （冰雹）. Suddenly， there is a loud sound， like a train or a jet plane. Sometimes， two， three， five， ten or more tornadoes can form over a large area.

This type of tornado activity hit Oklahoma and Kansas in May 1999. The day was stormy， with heavy thunderstorms in the afternoon. As the storms continued， tornadoes began to form. Dozens of tornadoes hit towns and neighborhoods in Oklahoma， then in Kansas. Some stayed on the ground for several hours， destroying everything they touched. The tornadoes killed 43 people and injured 600 others. They destroyed thousands of homes and businesses. In some areas， not one home stood. In some areas， the tornadoes destroyed every home on the left side of the street， but didn’t touch any homes on the right side. In other areas， the tornadoes lifted people and cars into the air and then threw them back down to earth.

So it is important to know where to hide and how to protect yourself in the face of a tornado.
