In aviation weather, what does CBS refer to?

• A. Cumulonimbus thunderstorms
• B. Cirrus-based storm
• C. Cold basin system
• D. Convective boundary surface

Answer: (A)

CBS stands for cumulonimbus thunderstorms. Cumulonimbus clouds are tall, vertically developed storm clouds that bring the most intense weather, including heavy rain, hail, lightning, strong updrafts and downdrafts, gust fronts, and often wind shear and turbulence. In flight, hearing CBS signals you should expect significant convective activity and plan to avoid or minimize time near these storm cells, using radar, vectors, and altitude changes as needed. The other options don’t match recognized aviation weather terminology for hazardous convective activity, so they aren’t used to denote storm hazards in practice.
