Final answer:
The statement is True. Doppler radar allows meteorologists to issue advanced tornado warnings by detecting and tracking motion in storms.
Step-by-step explanation:
The statement given is True. Data provided by the WSR-88D Doppler network allows meteorologists to issue advanced tornado warnings, often minutes before an actual tornado touchdown occurs. Doppler radar uses the Doppler effect to detect and track motion of precipitation particles in the atmosphere. By analyzing the changes in frequency of the radar waves reflected by the particles, meteorologists can determine the wind velocity and rotation in storms, which helps in predicting tornadoes
