How do weather radar images show storms and rainfall?
WeatherTechnology
Quick Answer
Radar sends out microwave pulses and measures echoes from raindrops, snow, or hail. Stronger echoes usually mean heavier precipitation.
The Full Story
Weather radar works by transmitting radio waves that bounce off precipitation particles in the atmosphere. The returning echo tells meteorologists where rain, snow, or hail is located and how intense it may be. Modern Doppler radar can also detect motion within storms by measuring shifts in the returned signal, helping forecasters spot rotation and wind patterns. In the United States, the NEXRAD network has been a major part of storm detection since the 1990s.
Key Facts
1.Radar echoes can reveal precipitation location and intensity
2.Doppler radar can estimate wind motion inside storms
3.NEXRAD has been operational in the U.S. since the 1990s
