Understanding Weather Radar Technology
Weather radar technology has evolved significantly over the years, providing increasingly detailed and accurate information. Modern radar systems use Doppler technology, which measures the speed and direction of precipitation, giving a more complete picture of weather patterns.
How Weather Radar Works
- Emission of Radio Waves: Radar systems emit pulses of radio waves into the atmosphere.
- Reflection from Precipitation: These waves bounce off raindrops, snowflakes, and hailstones.
- Detection and Measurement: The radar system detects the reflected waves and measures their intensity and frequency.
