A Vortex of Destruction
By, Anderson Umoru, Katherine Rudin and Kassandra Ferreira
What is a Tornado?
An upright spinning column of air.
- when air moves upward.
- something that can be ruined or destroyed
- remains of anything that was broken.
- a system that produces severe thunderstorms
- a whirling mass of air, especially one in the form of a visible column or spiral, as a tornado
Why are Tornadoes so Dangerous?
How are they Measured or Recorded?
The EF scale is the most common scale used for a tornado
It measures the tornadoes based on the wind damage
EF Scale stands for- Enhanced Fujita Scale
A tornado is measured by wind speed (mph)
The air inside a tornado ranges from 100km to 500km which is measured by the EF scale
The Fujita Scale measures how fast the tornadoes spin
Sometimes, tornadoes can spin up to 300 mph
Saturia–Manikganj Sadar Tornado
Happened in the Manikganj district of Bangladesh
Occured on April 26, 1989
It killed 1,300 people
It injured 12,000 people
It is expected to be the deadliest on recorded in history
The tornado struck around 6:30 am
the storm traveled 10 mile long and 1 mile wide
Town were left to ruins
It left 80,000 people homeless
It lasted 1.5 hours
After the tornado many people were starving and disease spread
It cost over one million dollars
A tornado is a spinning, column of air that is one of the most destructive natural disasters in the world
Tornadoes usually form because of the warm, wet winds meet cold, dry winds
Tornadoes last for about an hour, and can spin really quickly
Tornadoes can form when warm air goes updraft and wet winds mix together.
Cold winds are pushed to the bottom and the warm air rises faster and begins to spin counterclockwise
The spinning air inhales warm air from above the ground, causing the tornado to move faster and faster
Colorado USA Tornado
It happened on June 13, 1984
No injuries occurred
The width was 50 miles
The length was 1 mile long
It was a 1 on the fujita scale
It lasted 9 hours and 40 minutes
There was a lot of a hail, making it one of the worst and second costliest storm in Denver history
It cost about $276 million in hail damage
Flying debris can injure people
Houses are crushed
Tornadoes can pick up cars, houses, trees, and people
Anything picked up from a tornado can be carried many miles
Tornadoes can hurl objects
