Weather radar is an essential tool used by meteorologists to monitor and track weather patterns, including precipitation, thunderstorms, and severe weather events. By emitting radio waves and analyzing the reflected signals, weather radar systems can detect the size, location, and movement of precipitation particles, such as raindrops or snowflakes. Doppler weather radar systems can also measure the velocity of storm systems, providing valuable data on wind speed and rotation, which is critical for early warnings of severe weather conditions, such as tornadoes or hurricanes.
