In METAR reports, what does "BR" refer to?

Mist
Barometric Rise
Base Rate
Brisk Winds

The correct answer is: Mist

In METAR reports, "BR" stands for mist, which is characterized by very light precipitation with visibility slightly reduced, generally between 5/8 mile and 6 miles. This commonly encountered weather phenomenon can occur at any time and often appears in conditions with high humidity and light winds, resulting in the moisture condensing in the air. Understanding METAR codes is crucial for pilots and aviation professionals since these reports communicate essential weather conditions affecting flight operations. Mist is generally less severe than fog, which has stricter visibility criteria. Recognizing these terms helps pilots make informed decisions about their flight paths, ensuring safety and compliance with visual flight rules. While barometric rise and the other options pertain to various weather or atmospheric concepts, they are not represented by the "BR" code in METAR reports. This distinction is essential for interpreting aviation weather information accurately.
