What is the function of a Doppler radar in aviation weather?

• A. To record flight data
• B. To detect precipitation, its intensity, and movement
• C. To forecast wind patterns
• D. To measure atmospheric pressure

Answer: (B)

The function of a Doppler radar in aviation weather is primarily to detect precipitation, its intensity, and movement. This type of radar is specifically designed to measure the speed and direction of precipitation particles as they move, which is crucial for understanding storm dynamics and tracking severe weather events.

By utilizing the Doppler effect, the radar can determine how fast precipitation is moving toward or away from the radar site. This capability allows meteorologists to analyze not just where precipitation is occurring, but also how it is changing over time, which is vital for pilots and air traffic controllers to make informed decisions about flight paths and safety.

In the context of aviation, having accurate real-time data on precipitation is essential for navigating weather-related hazards, such as thunderstorms, which can significantly affect flight safety and efficiency.
