A tornado is a violently
rotating column of air that is
in contact with both the
surface of the earth and
a cumulonimbus cloud or, in
rare cases, the base of a
cumulus cloud.
Various types of tornadoes
include the land
spout, multiple vortex tornado,
and waterspout. Waterspouts
are characterized by a spiraling
funnel-shaped wind current,
connecting to a large cumulus
or cumulonimbus cloud.

Most tornadoes form from
thunderstorms. You need
warm, moist air and cool,
dry. When these two air
masses meet, they create
instability in the
atmosphere.
A change in wind
direction and an increase
in wind speed with
increasing height creates
an invisible, horizontal
spinning effect in the
lower atmosphere.
The cloud is white or
light gray while the funnel
remains suspended from
the cumulonimbus cloud.
When it makes contact
with the ground is a dark
gray or black color due to
the dust and debris that
are sucked from the
ground by the violent
vortex. They usually
rotate counter clockwise
in the northern
hemisphere

The tornado formed in
connection with a thundercloud,
called "Cumulonimbus".
Tornado appears at the base of
the cloud "Cumulonimbus" and
extends down to reach the soil
funnel.
A tornado is commonly
accompanied by rain, lightning,
hail, lightning and clouds of
darkness.
A common characteristic is
the low atmospheric pressure
(force per unit area exerted
on a particular surface) in the
center of the storm and
enormous wind speed.
Tornadoes move
approximately 50 Km/h,
however, some move slowly,
while others reach speeds of
100 Km/h or more.

in buildings with steel or
concrete.
You are going to keep open
some windows of the House,
preferably on the opposite side
from where the wind blows, but

If you are inside a building, it is
suitable you will lie on the floor

You are going to stay away from
the windows.

In the case of not having
basements, you are
going to seek protection
under heavy and solid
furniture in the central
part and ground floor,
of not having these
media covered with a
mattress.
