We often hear about natural disasters in the news. In your opinion, what are the most terrible natural disasters? Tornadoes(龙卷风) are one of the worst natural disaster events on the earth. Each year, tornadoes kill many people. The storms often carry homes, cars and trees from one place to another. And they can also destroy anything when they pass by.
A tornado forms in a rainstorm and extends(延伸) from the sky down to the ground. It is big at the top and small at the bottom.
A tornado appears when winds in different directions meet in the cloud and begin to turn in circles. People can see tornadoes almost everywhere in the world. But most happen from late winter to mid - summer in the US. There is a second high season in November. During spring, warm air moves north and mixes with the cold air left from winter. In November, the opposite happens. Cold air moves south and mixes with the warm air left from autumn.
Tornadoes always come suddenly. Weather scientists have done something to predict tornadoes. But the storms often move too fast for people to protect themselves.
