Tornadoes are one of nature's most violent storms, and they happen in various parts of the world. they can form at any time of the year, although many occur in the spring. a tornado is a spinning, whirling wind. when it meets with cold air it takes the shape of a long funnel or tube, reaching down from a large cloud. it is formed when warm air near the earth's surface rises and meets with cold air. when the weather conditions are right, this warm air starts to twist as it rises, getting faster and stronger. it is a bit like watching water disappear down the plughole in your bathtub. if this huge, twisting rope of air hits the ground, it may cause great damage. tornadoes can reach speeds of more than 250 mph, ripping roofs from houses, uprooting trees, and tossing heavy objects like cars in the air. буквами на , напишите
