In the provided METAR, what does 'BKN' indicate?

The term 'BKN' in a METAR report indicates "broken clouds." In aviation weather reports, various abbreviations are used to describe cloud coverage, which is vital for flight operations and safety. Broken clouds refer to a situation where the sky is more than half covered by clouds but less than fully overcast, specifically between 5/8 to 7/8 of the sky. This is critical information for pilots and dispatchers as it helps them assess visual flight rules (VFR) conditions and make informed decisions regarding flight plans and altitudes.

Understanding cloud coverage categories is essential in aviation meteorology. Clear skies, clouds at or below 1,000 feet, and no significant weather are important descriptors, but they do not correspond to the meaning of 'BKN' in the context of METAR reports. Recognizing the significance of broken clouds helps in interpreting weather reports effectively for safe aircraft operations.
