tornado
What is a tornado?
a violently rotating column of air, a destructive storm, that extends from a thunderstorm cloud down to the ground
What cloud forms a tornado?
cumunolimbus
hat's the difference between a hurricane and a tornado?
Hurricanes are large, rotating storms that form over warm ocean waters, while tornadoes are smaller, rapidly rotating columns of air that form from thunderstorms, often associated with hurricanes
What conditions lead to tornado formation?
Tornadoes form when thunderstorms develop in unstable atmospheric conditions, including warm, moist air near the ground and cooler, drier air aloft, along with wind shear (a change in wind speed and/or direction with height)
What should I do if I'm outside when a tornado warning is issued?
if you are outside and a tornado warning is issued, your first priority is to seek shelter in a sturdy building, or if none are available, find a low-lying area like a ditch or ravine and lie flat, protecting your head.
How do tornadoes form?
when a rotating column of air, called a mesocyclone, is drawn towards the ground, often due to wind shear and instability in the atmosphere
What are cumulonimbus clouds?
They are the only clouds that extend through all three cloud levels
Where do hurricanes and tornadoes typically occur?
Hurricanes form over warm tropical waters, while tornadoes are most common in regions with frequent thunderstorms, such as the "Tornado Alley" in the central United States.
What are the typical characteristics of a tornado?
Tornadoes can have wind speeds ranging from nearly stationary to over 200 mph, and their paths can range from a few minutes to several hours.
What if I'm in a vehicle during a tornado?
if you are in a vehicle, the best course of action is to drive to the closest shelter. If you cannot reach a shelter, pull over, get out of the vehicle, and find a low-lying area, like a ditch or ravine, and lie flat, protecting your head.
What are the different types of storms that can produce tornadoes?
supercell thunderstorms
What weather is associated with cumulonimbus clouds?
Cumulonimbus clouds are known for producing thunderstorms and severe weather, including heavy rain, hail, lightning, and even tornadoes.
Can hurricanes cause tornadoes?
Yes, hurricanes can spawn tornadoes, especially as they move inland and interact with cooler, drier air.
What are some signs that a tornado might be approaching, even if you don't see a funnel cloud?
Look for dark, green skies, a loud roar, a wall cloud (a low, dark cloud extending from the base of a thunderstorm), and a sudden calm before the storm, followed by very strong winds and debris.
what if im in school during a tornado?
If you are in school during a tornado warning,follow your school's tornado drill procedures, move to a designated safe area
How long do tornadoes usually last?
a few minutes, but some can last for more than an hour
How do cumulonimbus clouds form?
Cumulonimbus clouds can form alone, in clusters, or along squall lines.
What should I do during a tornado warning?
Seek shelter in a basement, storm cellar, or an interior room of a sturdy building, away from windows, and stay there until the tornado passes.
What is the Enhanced Fujita Scale (EF-Scale), and what does it measure?
The EF-Scale classifies tornado intensity based on the estimated maximum wind speed and the type of damage caused, ranging from EF0 (weakest) to EF5 (strongest).
what if i'm flying above a tornado?
If you are flying above a tornado, pilots and air traffic control will prioritize safety by rerouting the aircraft away from the storm, and if necessary, diverting to a different airport.
How fast do tornadoes move?
nearly stationary to over 70 mph, with an average speed of around 30 mph
What are some characteristics of cumulonimbus clouds?
The top of the cloud can extend to the highest layer of the troposphere
How do I prepare for a hurricane?
Monitor weather alerts, have an emergency kit ready, secure your home, and be prepared to evacuate if instructed by local authorities.
What is the difference between a tornado watch and a tornado warning?
A tornado watch means that conditions are favorable for tornadoes to develop in the area, while a tornado warning means that a tornado has been sighted or indicated by radar, and immediate action is needed to seek shelter.
what if the tornado forming right above my head
seek immediate shelter in a sturdy building's lowest level, away from windows, or lie flat on the ground, covering your head, if no such shelter is available.
