HOW "TORNADO" IS FORMED.

        hi frnds,let me share some interesting stuffs with u all.i like to know alot about the nature and history of the world.Now,i found a topic about the tornadoes,one of the most worst natural disaster in the world.Let me tell u wht i know, Tornadoes is one of the most violent storms and it is spawned from powerful thunderstorms.A tornado is funnel-shaped clouds and with rotating winds extends to the ground that can reach 300 milies per hour.It causes fatilities and demoilitions our neighbourhood within few seconds.Damages pathscan be in excess of one mile wide and one mile long.
      Some tornadoes are clearly visible, while rain or nearby low-hanging clouds obscure others.Occasionally, tornadoes develop so rapidly that little, if any, advance warning is possible.Before a tornado hits, the wind may die down and the air may become very still.A cloud of debris can mark the location of a tornado even if a funnel is not visible.Tornadoes generally occur near the trailing edge of a thunderstorm. It is not uncommon to see clear, sunlit skies behind a tornado.

The following are facts about tornadoes:


  • They may strike quickly, with little or no warning.
  • They may appear nearly transparent until dust and debris are picked up or a cloud forms in the funnel.
  • The average tornado moves Southwest to Northeast, but tornadoes have been known to move in any direction.
  • The average forward speed of a tornado is 30 MPH, but may vary from stationary to 70 MPH.
  • Tornadoes can accompany tropical storms and hurricanes as they move onto land.
  • Waterspouts are tornadoes that form over water.
  • Tornadoes are most frequently reported east of the Rocky Mountains during spring and summer months.
  • Peak tornado season in the southern states is March through May; in the northern states, it is late spring through early summer.
  • Tornadoes are most likely to occur between 3 p.m. and 9 p.m., but can occur at any time.
