Task: Class Definition Understanding (ontology: Earth_Environment/SWEET)

Which of the following definitions best describes 'local storm'?

A. A storm of mesometeorological scale; thus, thunderstorms, squalls, and tornadoes are often put in this category.
B. The process by which a single convective cell splits into two supercells, one dominated by cyclonic rotation and the other by anticyclonic rotation, their paths then deviating substantially from each other and other nearby convective cells.
C. A storm characterized by a fall of freezing liquid precipitation. The attendant formation of glaze on terrestrial objects creates many hazards.
D. A cyclonic storm off the east coast of North America, so called because the winds over the coastal area are from the northeast.

Answer: A storm of mesometeorological scale; thus, thunderstorms, squalls, and tornadoes are often put in this category.
