 Tornado debris signature

A Tornado Debris Signature (TDS) is a specific pattern observed in radar data that indicates the presence of a tornado and the associated debris being lifted into the atmosphere. When a tornado occurs, it can pick up various materials from the ground, such as dirt, leaves, and man-made objects, and fling them into the air. This debris can create a distinct radar signature. Meteorologists use Doppler radar to detect these signatures during storm events.
