Strong, rotating thunderstorms

Strong, rotating thunderstorms

• A. Cumulonimbus Cloud
• B. Cirrus Clouds
• C. Altostratus/Altocumulus Clouds
• D. Supercells

Answer: (D)

Strong, rotating thunderstorms are best described as a supercell, a highly organized, long-lived type of thunderstorm that hosts a deep, persistent rotating updraft called a mesocyclone. The rotation arises from wind shear in the environment, where winds change with height, tilting and sustaining the updraft. That rotating structure makes the storm exceptionally intense and capable of producing very large hail, damaging winds, and sometimes tornadoes. A cumulonimbus cloud describes the storm cloud itself, but not all cumulonimbus storms develop the persistent rotation that defines a supercell. Cirrus clouds are high, wispy formations unrelated to these strong, rotating storms, and mid-level altostratus or altocumulus clouds indicate different cloud classes rather than the organized rotating mechanism seen in a supercell.
