What weather devices can detect the threat of a tornado?
The main tool is Doppler radar, which can remotely measure wind speed and direction. This can be used to find rotation in a storm associate with a possible tornado. Another, recently developed tool is dual-polarized radar. Unlike conventional radar, this radar can distinguish between rain, hail, and tornadic debris.
