  • 2. TORNADO TORNADO CYCLE
  • 3. A tornado is a violently rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. Tornadoes come in many shapes and sizes, but they are typically in the form of a visible condensation funnel, whose narrow end touches the earth and is often encircled by a cloud of debris and dust. Changes in the air layer is the trigger of tornadoes. In this case if the cold air layer is above the layer of hot air, hot air rises with the speed of 300 km/h, the air that infiltrated from the side which causes the swirling wind to form a tornado, and when it is perfect then a tornado could have speeds up to 400 km/h and the width of the chimney between 15-365 meters.
  • 4. Hot air which continuously hits the earth will cause the temperature of the soil increases. How Tornado Happen?
  • 5. And when the hot temperatures rise, the hot air and humid in the air will begin to rise and the rose.
  • 6. When the hot air, cold air and moist air meet dry air, and lifts up, and then they will go to the upper air layers. In this phase a thunder cloud began to be created. And storm quickly develops
  • 7. Upward air movement occurs very quickly and the wind from different directions on the side causes the formation to form a vortex
  • 8. A cone of revolution the spiral air begins to form and it can be seen from the cloud to the ground.
  • 9. A cone of revolution the spiral air begins to form and forms a tornado.
