      • Types of tornadoes
      • Effects of Tornado
      • Tornado safty
    • Interoduction
      • A localized and violently destructive windstorm occurring over land characterized by a funnel-shaped cloud extending toward the ground
      Defination of tornado
    • Characteristics
      • Tornado generally apperes in funnel shape
      • Most Tornadoes have wind speeds between 40km/h and 110km/h.
      • Majority if Tornadoes in the world occur in the Tornado Alley region of the United States also occur in North America, South Africa, South-Centeral and eastren Asia,Australia,New Zealand,Philippines.
    • Continued
      • At each year more then1000 Tornadoes hit the united states
      • A typical tornado travels at around 10-20 miles per hour.
      • Most tornadoes occur during the months of May, June, July and August in the late afternoon and evenings
    • Continued
      • Tornadoes generally travel from the southwest at an average speed of 70 miles per hour.
      • Torando rotates in circle in a counter clockwise direction.
      • Scientests generally this roatation is called mesocyclone.
      • A tornado is also commonly referred to as a "twister".
      • The term "cyclone" is used as a synonymfor "tornado"
    • Torando formation
      • Most tornadoes form from thunderstorms.
      • You need warm, moist air from the Gulf of Mexico and cool, dry air from Canada. When these two air masses meet, they create instability in the atmosphere.
    • Continued
      • A change in wind direction and an increase in wind speed with increasing height creates an invisible, horizontal spinning effect in the lower atmosphere.
      • An area of rotation, 2-6 miles wide, now extends through much of the storm.
      • Most strong and violent tornadoes form within this area of strong rotation.
    • Types of tornadoes
      • A waterspout is a tornado over water. A few form from supercell thunderstorms, but many form from weak thunderstorms or rapidly growing cumulus clouds. Waterspouts are usually less intense and causes far less damage.
      1.weater support
    • Continued Generally weaker than a supercell tornado, a landspout is not associated with a wall cloud or mesocyclone. It may be observed beneath cumulonimbus or towering cumulus clouds and is the land equivalent of a water support 2.Land support
    • Effects of Tornado
    • Effects of Tornado
      • 1. Tornadoes can make People die.
      • 2. At each year 5000 average number of people were died.
      • 3. The most extreme tornado in recorded history was the Tri-State Tornado.
      • 4.which roared through parts of Missouri, Illinois, and Indiana on March 18, 1925.
    • Continued
      • 5. it is the deadliest single tornado in United States history (695 dead).
      • 6. The deadliest tornado in world history was the Daultipur-Salturia Tornado in Bangladesh on April 26, 1989, which killed approximately 1300 people.
    • Continued
      • On May 21, 1950, a tornado which touched-down at Little London (Buckinghamshire) tracked 107.1 km toCoveney. From there it continued as a funnel cloud, travelling another 52.6 km to Shipham (Norfolk) where it was last seen disappearing out across the North Sea.
