• Causes of Tornado
3.Types of tornado
4.Effects of tornado
• Effects
• Major tornado events
5.Tornado Mitigation
• A tornado is a violently rotating column of air that extent from a
thunderstorm to the ground.
• it’s also called “TIWSTER”.
• These spinning columns of wind can take variety of shapes such as
rope, funnel, cylinders.
• Every tornado must extend downward form cumulonimbus to ground.
• The funnel shaped tornado that haven’t touched the ground are called
”FUNNEL CLOUDS”
WHAT IS TORNADO
TORNADO FORMATION
• Causes of tornado formation
• Suitable climatic conditions
• Extremely large thunderstorm
• Supply of wind
• Unstable wind shear
Stages of formation of tornado
• Tornado form where there are large difference in atmospheric
pressure.
• Often results during a major storm such as “SUPERCELL”
thunderstorm.
• Supercell is a large rotating thunderstorm which possess mesocyclone
having a ability to updraft massive cloud to rotate inside.
Formation of horizontal wind
shear
• Due to vertical difference in wind speed
horizontal wind shear develops.
• Rotating speed increase with height.
• Supply of leads to grow big horizontal rotating
air cylinder.
• It is an important factor in meteorology,
particularly when studying weather systems like
thunderstorms, tornadoes, and general
atmospheric stability.
Classification of Tornado
• Week tornado
• Strong tornado
• Violent tornado
Other types of tornado
• Supercell Tornado
• Landspout Tornado
• Gustanado
• Waterspouts
• Dust Devil
• Fire Tornado
Supercell Tornado
• A supercell tornado is a type of tornado
that forms in association with a supercell
thunderstorm.
• A rotating updraft is a key to the
development of a supercell ,and
eventually a tornado .Once the updraft is
rotating and being fed by warm, moist air
flowing in at ground level, a tornado can
form.
Landspout Tornado
• The spinning motion originates near
the ground. waterspouts are similar
to landspouts except they occur over
water.
• The spinning motion originates near
the ground.
• Waterspouts are similar to
landspouts,except they occur over
water.
GUSTANADO
• A gustanado is a shallow surface-based vortex which forms within the
downburst emanating form a thunderstorm.
Water spouts
• Waterspouts are tornadoes that form over water,or move from land
to water.
DUST DEVIL
• Dust devil ,also called sand devil, small,
spinning wind occurring most frequently in
the early afternoon when a land surface is
heating rapidly.
• Dust devils are occasionally made visible by
the full of dust,leaves,or other loose matter
from the surface.
Fire tornado
• Fire tornado is a whirlwind induced by
a fire and often (at least partially)
composed of flame or ash.
• These start with a whirl of wind, often
made visible by smoke, and may occur
when intense rising heat and turbulent
wind conditions combine to form
whirling eddies of air.
EFFECTS OF TORNADO
• Loss of life
• Property damage
• Effects of nature
• Lightning
• Pyschological effects
