About
tornadoes
An extremely rapidly
rotating column of air
that extends from a
cumulonimbus cloud
to the Earth's surface.
Tornadoes come in a
variety of shapes and
sizes, and are often
(but not always) seen
as a condensation
funnel around which
debris and dust swirl.

Tornado
outbreak
is the occurrence of multiple tornadoes spawned by the same
convective storm system. There is uncertainty about how many
tornadoes are needed for an outbreak to become official, but it is
typically between six and ten,
there must be at least two different places of their
origin, or at least two supercells

Tornado formation
CAUSE 1
Contrast of air masses:
Warm, moist air from
below and cold, dry air
from above create
conditions for the rise of
warm air.
CAUSE 2
CAUSE 3
Atmospheric instability:
Sudden changes in
temperature and
humidity make the
atmosphere unstable.
Wind shear: Different
wind speeds or
directions at different
altitudes cause the air to
swirl into a horizontal
cylinder, etc.
