A sucks more air and possibly objects inside. Tornadoes

A tornado is a mass with air with high angular velocity whose lower end
is a contact with the surface of the Earth and the superior one with a Cumulonumbus
cloud or, exceptionally, with the base of a cumulus cloud. This is the cyclonic
atmospheric phenomenon of greater energy density of the Earth. Mexico is not
exempt, and towards South America the phenomenon can be generated in places
like the Pampa Argentina, Bolivia, Chile and the Amazon. For it to be formed,
higher currents are necessary, strong winds, the entrance of hot and humid air,
and cold air and dry.

A tornado begins with a severe storm. The same property that keeps a
storm active, also gives rise to most tornadoes. The wind that joins the storm
begins to swirl and forms a funnel. The air inside the funnel turns more and
more quickly and generates an area of very low pressure, which sucks more air
and possibly objects inside.

 Tornadoes are presented in
different sizes and forms but generally they have the form of a funnel cloud
whose narrowest end touches the ground is usually surrounded by a cloud of
debris and dust, at least in its first moments. Most of the tornados count on
winds that arrive at speeds of between 65 and 180 kilometers.


most dangerous tornadoes in the world :

most dangerous tornado that happened in the country of Daulatpur and Saturita
in the year 1989 of April 26, this tornado destroyed an area of 6 kilometers.

second tornado more dangerous than happened in the country of Daca and Comilla

capitak, Daca, killing 600 people.

third tornado more dangerous than happened in the country of Tri-State in  U.S.A. in the year 1925, the tornado killing
de double of people than the second tornado more dangerous than happened in the
country of Daca and Comilla.

fourth tornado more dangerous than happened in the country Bangladesh, occurred
concretely in the subdivision of Magnikganj, capital district, Daca, on April
17, 1973. In the town of Balurchar not a single dwelling remained standing, the
village was completely devastated.

Characteristics of the Tornadoes:

The tornado is formed in connection with a storm cloud, called  ¨ Cumulonimbus¨.

The tornado appears at the base of the cloud ¨ Cumulonimbus ¨ and extends
downwards until reaching the ground in the form of a funnel or sleeve.

Commonly a tornado is accompanied by rain, hail, lightning, lightning and the
darkness of the clouds.

A common feature is the low atmospheric pressure ( force per unit area, exerted
on a given surface ) in the center of the storm and enormous wind speed.

The destruction effect of a tornado is greater in the affected area than that
of a hurricane, because the energy to be released concentrates a smaller area.
Therefore the effect of the wind spend and the low pressure causes that the
damge is greater.

Tornadoes move about 50 Km / h, however, some move slowly, while others reach
speeds of 100 km /h or more. The average trajectory of a tornado is about 400
meters wide and a few kilometers long. Some of these have reached exceptional
values of 1.6 Km wide and 480 Km long.

security advice:

Get ready for a tornado by stockpiling emergency supplies such as food, water,
medicine, batteries, flashlights, important documents, road maps, and a tank
full of gas.

When a tornado approaches, everyone in your path should take refuge in doors,
preferably in a basement or in an interior room or hallway on the ground floor.

Avoid windows and protect yourself as much as possible by placing yourself
under large, solid furniture.

Avoid cars and caravans, which offer virtually no protection against tornadoes.

If you are surprised at the outdoors, lie in some depression of the ground or
in low places and wait for the storm to pass.
