Final answer:
The statement that landspouts typically develop out of supercell thunderstorms is false. Supercells produce significant tornadoes with a rotating updraft, while landspouts form from vortexes near the ground and are not associated with supercells.
Step-by-step explanation:
Landspouts do not typically develop out of supercell thunderstorms, which makes the statement false. Supercell thunderstorms are characterized by a deep, persistently rotating updraft and are known for producing severe weather phenomena, including significant tornadoes. Landspouts, on the other hand, are more similar to waterspouts in that they form during the growth stage of a convective cloud.
They are not associated with a rotating updraft like those in supercells. Rather, they are often weaker and typically form from a vortex of wind near the ground that is drawn upwards by growing cumulus or cumulonimbus clouds.
Tornadoes can be observed as descending from clouds in funnel-like shapes that spin violently, representing rotational motion in nature. These are usually associated with supercells, unlike landspouts. This distinction is important to understand when studying the mechanisms behind different types of severe weather events.
