  1. Tornadoes

  2. Tornado Facts Tornado: a localized and violently destructive windstorm occurring over land characterized by a funnel-shaped cloud extending toward the ground.

  3. What causes a tornado? • Tornadoes are most often spawned by giant thunderstorms known as "supercells." These powerful, highly organized storms form when warm, moist air along the ground rushes upward, meeting cooler, drier air. As the rising warm air cools, the moisture it carries condenses, forming a massive thundercloud, sometimes growing to as much as 50,000 ft. in height. Variable winds at different levels of the atmosphere feed the updraft and cause the formation of the tornado's characteristic funnel shape.

  4. Conditions that lead to a tornado Large dark low lying cloud, large hail, loud roar.Warm humid air mass meets with a cool dry air mass.

  5. Some important facts A tornado is very powerful and can sweep up anything in its path. So, if you are in its path, you should try to move away from this rapidly moving monster! Make sure you always stay calm and try to stay as safe as you can!

  6. Although tornadoes occur in many parts of the world, these destructive forces of nature are found most frequently in the United States east of the Rocky Mountains during the spring and summer months. In an average year, 800 tornadoes are reported nationwide, resulting in 80 deaths and over 1,500 injuries. A tornado is defined as a violently rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of 250 mph or more. Damage paths can be in excess of one mile wide and 50 miles long. Once a tornado in Broken Bow, Oklahoma, carried a motel sign 30 miles and dropped it in Arkansas!

  7. Some ways to keep safe • Stay calm.Seek shelter IMMEDIATELY!Keep a portable TV/radio and flashlight in your shelter.Wear shoes to protect your feet from broken glass and other debris left by the storm.Protect head and chest--crouch, face to floor, hands behind head.Cover yourself with blankets, pillows or coats.Hide under sturdy furniture.Avoid candles, gas lanterns and oil lamps.In schools and offices: seek designated shelter in interior rooms or hallway's on ground floor, or lowest floor possible. Avoid auditoriums and gymnasiums.In shopping malls, seek the smaller interior shops on the ground floor.In shopping centers, avoid large open rooms as well as the south and west walls.Evacuate mobile homes and vehicles! Seek shelter in substantial structure, ditch or culvert.
