How is vertical visibility expressed in METAR reports?

• A. As a temperature
• B. Using the format "VVxxx"
• C. With the term "Ceiling Height"
• D. In feet only

Answer: (B)

Vertical visibility is expressed in METAR reports by using the format "VVxxx." In this notation, "VV" stands for vertical visibility, and "xxx" represents the measurement in feet. This format provides pilots and meteorologists with a clear and standardized way to report how far one can see vertically through obscured conditions, such as fog or heavy precipitation. The use of "VV" ensures that the information is easily recognizable and interpretable within the context of aviation weather reporting. In contrast, other options do not accurately represent how vertical visibility is communicated. Expressing vertical visibility as a temperature does not align with its definition, and using the term "Ceiling Height" refers specifically to the height of the cloud base above the ground, which is different from vertical visibility. Additionally, while vertical visibility can be indicated in feet, the answer format must include the "VV" prefix to properly classify it in METAR reports.
