What does TVS stand for?

• A. Tornado Velocity System
• B. Tornadic Vortex Sensor
• C. Tornadic Vortex Signature
• D. Tornado Vortex Spectrum

Answer: (C)

Tornadic Vortex Signature is the radar feature meteorologists use to indicate a tornado may be present in a storm. It refers to a very localized, strong rotation detected by Doppler radar near the storm’s lower levels, seen as a tight velocity couplet (inbound velocity next to outbound velocity). This signature points to a vortex that is near the ground, making it a critical signal for tornado warnings. The other terms aren’t standard radar descriptions of this phenomenon, so they don’t match what the radar data is actually showing.
