What does weather radar primarily detect?

Weather radar is primarily designed to detect precipitation and assess storm intensity. This technology utilizes radio waves to identify and analyze the presence, type, and intensity of precipitation falling from clouds, whether it be rain, snow, sleet, or hail. By measuring the reflected signals, meteorologists can determine how heavy the precipitation is and provide insights into potential storms' severity.

This capability is crucial for weather forecasting and severe weather warnings, allowing for timely alerts about heavy rainfall, thunderstorms, or other hazardous conditions. Understanding the intensity of precipitation helps predict flooding, storm development, and overall weather patterns that affect safety and operations.

While other choices may relate to weather phenomena, they do not accurately represent what weather radar primarily detects; instead, they involve different instruments or methods for observation and analysis.
