How is a variable ceiling between 1,000 and 2,000 feet represented in column 14?

In the context of the Limited Aviation Weather Reporting System (LAWRS), a variable ceiling between 1,000 and 2,000 feet is represented in column 14 with the format that indicates both the lower and upper limits of the ceiling. The format typically used is CIG followed by the lower value and then V for variable, followed by the upper value.

The correct representation is "CIG 010V020," where "010" signifies the lower limit of the ceiling at 1,000 feet and "020" denotes the upper limit at 2,000 feet. The inclusion of "V" indicates the variability of the ceiling within that vertical range.

This format is essential for pilots and meteorologists as it conveys succinct information about cloud heights, which is crucial for flight planning and safety. Other variations in the answer choices do not conform to this required structure for a variable ceiling, either by providing incorrect ceiling values or by using different formats that don’t denote variability properly.
