What does the METAR decode "SCT020 V BKN" indicate?

The phrase "SCT020 V BKN" in a METAR report provides specific information about cloud cover. The correct interpretation of this coding indicates that there are scattered clouds at an altitude of 2,000 feet. The abbreviation "SCT" stands for scattered, which means that there is a relatively small amount of cloud cover at that altitude. The number "020" represents 2,000 feet above ground level.

Following that, "V BKN" indicates that there are broken clouds, but the "V" reflects variable coverage, often relating to the extent or variability of the broken cloud layer. This signifies that while scattering clouds are observed at 2,000 feet, the presence of broken clouds adds an additional layer of complexity regarding flight conditions at that altitude.

Overall, this interpretation assists pilots and air traffic controllers in assessing weather conditions, particularly in terms of cloud coverage and resulting visibility, which are critical for safe flying operations. This understanding is essential in the aviation field for making informed decisions regarding takeoff, landing, and in-flight navigation.
