How does radar detect storms?

Radar detects storms by emitting radio waves that bounce off precipitation particles like raindrops, snowflakes, or hail. The radar system measures the time it takes for the waves to return, allowing meteorologists to determine the distance, intensity, and movement of the storm. By analyzing the returned signals, radar can identify storm features such as rainfall rates, wind patterns, and the potential for severe weather, enabling timely warnings and forecasts.
