What is the meaning of "BKN" in a METAR?

"BKN" in a METAR refers to "Broken Clouds." In aviation weather reporting, METAR codes provide essential information about weather conditions and cloud cover. The term "broken" specifically indicates that between 5/8 and 7/8 of the sky is covered with clouds. This is significant for pilots and dispatchers, as it influences visibility, flight planning, and the assessment of potential weather hazards.

Recognizing cloud cover descriptions like "BKN" is critical for understanding the current weather conditions, particularly in the context of aircraft operations where cloud coverage can affect flight paths and safety protocols. The coding system used in METARs helps ensure that all aviation personnel interpret weather conditions consistently and accurately.
