TORNADO
A tornado is a fast rotating column
of air that forms the connection
between clouds or cumulonimbus in rareoccurrences of cumulus cloud
base with ground level. A tornado appears in many sizes but thecondensation funnel-shaped generally obvious that ends that
touches the Earth narrows and oftensurrounded
by clouds that bring debris.
Generally
the tornadoes have wind speeds of 177 km/h or
more with an average reach of 75 m and travels a
few kilometers before disappearing. Some of
the tornadoes which reached wind speeds of more
than 300-480 km/h has a width of more than one mile
(1.6 km) and can survive on the surface with more
than 100km. Although tornadoes have been
observed on every continent except Antarctica,
tornadoes are more commonin the United States. The Tornado also generally
occur in southern Canada, South–Central and
EasternAsia, East-Central South Africa, Latin
America, Central and North-Western Europe, Italy, Western
and Southern Australia, and New Zealand.

The definition of the
A
tornado near Seymour, Texas.
A tornado is defined
by the glossary of meteorology as a “rotating column of
air tight with the surface of thesoil and emerges from
the cloud cumuliform cloud cumuliform or the
bottom and often (but not always) appears as a funnel cloud.
Condensation Funnel
Tornado should
not appear; However, the intensity of low
pressure caused by the high wind speeds (seeBernoulli‘s
principle) and spin (related to cyclostrophic balance) often
causes water vapor condense in the air that
cause condensation funnel. The winds
of the Tornado Vortex is not
a cloud condensation.
