What do some strong downdrafts do to form a tornado?
Strong downdrafts that wrap around the rear of the storm help to bring the rotation down to the Earth's surface.
100
Who predicts tornadoes?
The Storm Predictor Center.
100
What type of cloud does a tornado start as?
A cumulonimbus cloud
100
What colours can the sky turn during a tornado?
Black, green, or yellow
100
Define mesocyclone
A small large-scale atmospheric wind-and-pressure system that arises near a thunderstorm
200
How is a mesocyclone created?
By strong updrafts in the storm and wind shear, which causes the air near the surface, whether ground or water, to spin horizontally like a rolling pin,This spin then tilts to a more or less vertical axis and is stretched by strong updrafts, which intensifies the rotation.
200
After the Storm Predictor Center notifies everyone, what do they do?
Send a certain researcher to follow every tornado in the tornado alley because that is where most tornadoes origin from.
200
What is F1,F2,F3,F4,F5,F6,F7,F8,F9,F10?
Markings on The Fugita Scale
200
How fast can tornadoes go?
Anywhere from 64.37 kilometers per hour to 609.92
200
Define RFD
A region of dry air wrapping around the back of a mesocyclone in a supercell thunderstorm.
300
How do the strong tornadoes often develop?
With storms that have a large area of strong wind rotation within the storm cloud.
300
Can tornadoes be prevented?
No
300
What is one of the things the funneling wind does?
It gains speed
300
What does a tornado warning mean?
A sighting of a tornado has been made
300
Define Tornado Alley
A place in United States of America where tornadoes mostly occur
400
What are the two things a tornado can form between?
A tornado can form at the boundary between the strong updrafts and downdrafts
400
Is it possible to prevent injuries from tornadoes?
Yes, Because people can predict them, so people know it is going to happen
400
What else does the funneling wind do?
Expands and touches down
400
How are tornadoes measured by?
The Fugita Scale
400
Define Fujita Scale
An instrument that measures damage caused by a tornado
500
How does cooler air help form a tornado?
meets warm and moist tropical air masses and the potential for severe weather is created.
500
Can tornadoes be predicted in advance?
Yes
500
Are watertop tornadoes called watertop tornadoes?
No, they are called waterspouts
500
What part of the tornado does the Fujita Scale measure?
