Module 9 Tornadoes & Winter Storms Flashcards
What types of clouds form thunderstorms that can lead to tornadoes?
Cumulonimbus clouds
These clouds are associated with severe weather, including thunderstorms and tornadoes.
What is the average speed of a tornado’s spinning funnel cloud?
110 mph, can reach 300 mph
Tornadoes can vary significantly in speed and intensity.
What is the diameter range of tornadoes?
300 feet to 1 mile
Tornado sizes can vary widely.
What is the Enhanced Fujita Scale used for?
To measure tornado intensity
The scale ranges from F0 to F5, with F5 being the most severe.
What is Doppler radar used for in relation to tornadoes?
To detect features forming that might cause tornadoes
It analyzes radar information to identify strong updrafts and potential tornado conditions.
What defines a blizzard?
Winds over 35 mph, temperature below -7°C (19.4°F), and reduced visibility
Blizzards are extremely dangerous due to these conditions.
What should you do if you are stuck in a car during a blizzard?
Stay in your car
Getting out can lead to freezing or getting lost.
What is a nor’easter?
A low-pressure storm system on the east coast of the US
It brings cold air from the northeast and can result in heavy precipitation.
What phenomenon causes lake effect snow?
Winds blowing over the Great Lakes picking up moisture
This results in heavier snowfall in areas near the lakes.
Which book of the Bible discusses God’s sovereignty over storms?
Nahum
The book addresses God’s power and judgment, including over natural storms.
What is wind shear?
When wind suddenly changes direction and speed
This is crucial in the formation of tornadoes.
What is a mesocyclone?
A large circulating updraft inside a supercell
It plays a key role in tornado formation.
Which region in the US is known as Tornado Alley?
Kansas, Missouri, Oklahoma, and Texas
This area experiences the highest frequency of tornadoes.
What is ‘Dixie Alley’?
A region in the southeastern US with increasing tornado activity
This area includes states like Tennessee, Arkansas, and Alabama.
True or False: Tornadoes are found only in the United States.
False
Tornadoes occur on almost every continent except Antarctica.
Fill in the blank: The Enhanced Fujita Scale incorporates __________ damage indicators.
twenty-eight
These indicators help improve the accuracy of tornado ratings.
