The tornado is considered one of the most destructive environmental phenomena in history, its origin is extremely confusing , however, it has been a discovery to discover the step by step of its formation , thus causing many individuals to be interested in the phenomenon; Likewise, meteorologists began an exhaustive search for its causes after knowing its form of origin.

What is a tornado?

It is considered a condensed and high-speed air mass, generally they have a conical or angular shape and their lower part touches the earth’s surface and in their upper part it has an extremely wide rectangular cloud, cloudy most of the time. It is an extremely peculiar natural phenomenon , which like the typhoon has a cyclical order and direction, in this way the semi vortex that is in it is created, it has an erratic energy , the density of its energy can even reach be more extensive than that of the earth , however, it islittle extension and its duration is extremely short.  Although these start from a cyclical movement like the typhoon , they have different shapes, sizes and densities, these are identified by the shape of the funnels, they measure around 75 meters high and have a speed of 65 to 180 kilometers per hour.

Most tornadoes are caused by a cold and dry air that descends from the top of a cloud, compensating and mixing with what is the warm air that rises, thus forming two air flows, the cold that is descending and the warm one that is rising, in this way when mixing they increase the dimensions of the cloud that collaborates in the formation of the tornado , gradually the cold air becomes heavier which causes thick layers of unstable air to be created that descend quickly, forcing the hot air to rise, thus beginning to form what is the eddy , this is usuallyMainly invisible, however, as the lower part of it connects with the earth’s surface and begins to raise dust, it becomes visible, thus completing what the tornado is.


Tornadoes are very easy to identify, however, some of their most essential characteristics will be described in the same way :

  • It is a mixture of hot and cold air, in opposite directions, a cold downdraft and a hot updraft.
  • Depending on their intensity is the damage they can cause.
  • It has a speed of 65 to 180 kilometers per hour.
  • They are generally around 75 meters tall.
  • It is invisible at startup, until random land and waste from the land surface begins.
  • It can happen in the same way in the ocean.
  • It has a conical or funnel shape , which connects on its lower side with the floor and on its upper part with an elongated nine.
  • Generally, the air that is created starting from both flows, both cold and hot, is dense and thick, surrounding the whirlpool as layers.

Types of tornado

There are three main types of tornadoes, which are the most mentioned:

  • Land waterspouts.
  • Multiple vortex tornadoes.
  • Waterspouts.

However, some variations of them are also recognized , which are called circulations , they may have the same beginnings, but they are not the same, which makes them simply similar, these phenomena are the following:

  • Gustnado.
  • Dust swirl.
  • Fire swirl.
  • Steam swirl.
  • Causes

One of its most common causes is air flow , however, many theorists have blamed environmental pollution for this, since unstable air currents can be the cause of these phenomena, however, there is no specific cause. scientifically proven.


Tornadoes do not have stages in themselves, however, at the time of their formation they go through individual processes that progressively come together, such as the condensation of air, hot air and cold mixing in opposite directions and the layers of air that are progressively formed, it could be said that these are in part the stages that a tornado goes through when it originates and reaches its full form.


The movements of the tornado are mainly vertical , one descending and one ascending, progressively and with the close contact of these two air currents a cyclical flow is given , which will generate the formation of the whirlpool that will end up being the tornado.

Effects edit

Some of the more common effects that can be witnessed after a tornado are the following:

  • Landslides of trees from the ground.
  • Houses, farms and other objects destroyed.
  • Disasters in a matter of dust, dirt and other things, which in the course of the whirlpool were accumulating.

What to do in the event of a tornado

The most common recommendations presented when a tornado hazard or warning occurs are as follows:

  • Take refuge in solid and well-founded establishments.
  • Preferably hide in a basement , to prevent risks.
  • Close all windows, doors, and other openings in the house and stay away from these as they can easily collapse and shatter and cause some damage.
  • Find low, flat places to hide while the tornado passes.


  • The Great Bend tornado in Kansas occurred in 1915.
  • Daulatpur and Saturia, Bangladesh, 1989.
  • Dhaka and Comilla, Bangladesh, 1969.
  • ‘Tri-State’, United States , 1925.
  • Manikganj, Bangladesh, 1973.
  • Valletta, Malta, 1551.
