Secondary radar functionality is not degraded by weather, which is a significant advantage when it comes to air traffic control and ensuring safe aircraft operations. Unlike primary radar, which relies on returning signals that can be impacted by precipitation, thunderstorms, and other atmospheric conditions, secondary radar operates using transponder signals from aircraft. This means that even in adverse weather conditions, secondary radar can continue to function effectively, providing accurate information about an aircraft's position, altitude, and identification. This reliability in various weather conditions enhances situational awareness for air traffic controllers, allowing them to manage air traffic more efficiently and safely.

The other options do not accurately reflect the roles or capabilities of secondary radar. For instance, while primary radar can be affected by weather, secondary radar's design focuses on aircraft communication and data verification, rather than storm tracking or collecting extensive weather data.
