When the ceiling height is variable, what is reported in the sky condition column?

The correct response reflects the practice of reporting sky conditions when the ceiling height varies. In such cases, the average of all observed heights is reported in the sky condition column. This method provides a comprehensive view of the cloud layer distribution, capturing the variability in ceiling height effectively.

While the minimum, maximum, or lowest layer might indicate specific individual observations, they wouldn't represent the overall ceiling condition accurately. Using the average gives a better indication of what pilots and meteorologists can expect during flight operations and aids in understanding the overall atmospheric conditions. This approach reflects a standard methodology in reporting and helps ensure that the information is consistent and useful for aviation purposes.
