Questions and Answers

What is the primary factor that differentiates a supercell thunderstorm from an ordinary thunderstorm?

Supercells result from the collision of warm, humid air with cold, dry polar air; ordinary thunderstorms do not require such specific atmospheric conditions.

Supercells exclusively occur in 'Tornado Alley', while ordinary thunderstorms do not.

Supercells are characterized by rotation and can last for hours, whereas ordinary thunderstorms typically last 30-60 minutes. (correct)

Supercells are always accompanied by tornadoes, while ordinary thunderstorms never produce them.

Which combination of air masses contributes to the formation of tornadoes in 'Tornado Alley'?

Warm, dry air from the Sahara Desert, cool, moist air from the Atlantic Ocean, and warm air from the Gulf of Mexico.

Dry air from the Rocky Mountains, warm, humid air from the Gulf of Mexico, and chilly Arctic air from the north. (correct)

Cool, moist air from the Appalachian Mountains, dry air from the Mojave Desert, and warm air from the Caribbean Sea.

Warm, humid air from the Pacific Ocean, cool, dry air from the Great Lakes, and warm air from the Gulf of California.

Why does the low-pressure area within a tornado's funnel exacerbate the storm's intensity?

It causes the funnel to change its trajectory, thus expanding the area of damage.

It accelerates the storm's movement across the land, leading to increased wind speeds.

It neutralizes the electrical charge within the storm, preventing lightning strikes.

It draws in more air and objects, intensifying the spinning motion and destructive power. (correct)

Flashcards

Tornado

A powerful rotating column of air extending from a thunderstorm to the ground.

Supercells

Severe rotating storms that can lead to tornadoes; formed by air temperature contrasts.
