weather radar
Precipitation detection system
Weather radar is a system that uses radio waves to detect precipitation, measure its intensity, and track its movement.
Meteorologists rely on it to monitor storms, predict severe weather, and issue warnings.
The familiar green-yellow-red maps on weather broadcasts come from weather radar data: The weather radar shows a line of thunderstorms approaching from the west.
