Tornado Formation and Meteorological Conditions

Play an AI-generated podcast conversation about this lesson

Considering the atmospheric conditions conducive to tornado formation, which scenario would be least likely to produce a tornado?

The convergence of cold, dry polar air with warm, moist tropical air.

A supercell thunderstorm characterized by a rotating column of air.

Stable atmospheric conditions with minimal temperature and moisture gradients. (correct)

An intersection of dry air from a mountain range with humid air from a large body of water.

If a region outside of 'Tornado Alley' experiences an unusually high number of tornadoes in a given year, what might be a plausible explanation, considering the factors that contribute to tornado formation?

An anomalous shift in the jet stream, causing atypical interactions between air masses. (correct)

A significant reduction in the Earth's magnetic field strength.

A sudden decrease in the average humidity levels disrupting normal weather patterns.

Increased volcanic activity leading to changes in atmospheric pressure.

Given that supercells can last for hours, while ordinary thunderstorms last between 30 to 60 minutes, what is the most likely reason why supercells are associated with tornado formation?

The prolonged duration of supercells allows for the sustained rotation and intensification necessary for tornado development. (correct)

Supercells have a weaker updraft, which allows the formation of a tornado at ground level.

Supercells always occur in densely populated areas, increasing the chances of tornado sightings.

Supercells are more likely to occur at night, when atmospheric conditions are more unstable.
