According to a METAR report, at what altitude AGL should the bases of convective-type cumuliform clouds be expected?

• A. 4,400 feet.
• B. 8,800 feet.
• C. 17,600 feet.
• D. 2,600 feet.

Answer: (B)

The bases of convective-type cumuliform clouds are typically formed as a result of rising air that can achieve buoyancy, causing the clouds to develop in a vertical column. According to meteorological standards and observations, the bases of these clouds can vary significantly based on local atmospheric conditions, including humidity and temperature. In standard conditions, the bases of convective clouds, particularly cumulus clouds, are generally found at altitudes that often hover around 8,000 feet above ground level (AGL). This altitude effectively represents a common height where favorable conditions for convective activity can exist, given typical temperature profiles and moisture content in the atmosphere. Therefore, when assessing a METAR report and determining where one would expect the bases of these types of clouds, the choice of 8,800 feet is closely aligned with the expected standard altitude for convective cloud bases. This understanding is crucial for pilots and meteorologists when making flight planning decisions or assessing weather conditions.
