How is a cumulonimbus cloud located to the north of the observation location and moving south encoded?

The encoding for clouds in aviation weather reports follows a specific format that aligns with the standard practices in meteorology. In this case, the correct encoding is "CB N MOV S."

This is because "CB" indicates that the cloud type is cumulonimbus, which is essential for pilots to be aware of due to its associated weather phenomena, including turbulence, precipitations, and potential thunderstorms. The "N" denotes that the cumulonimbus cloud is located to the north of the observation point, which provides critical positional context for situational awareness.

The phrase "MOV S" indicates that the cloud is moving south. This information is vital for understanding the potential impact on the weather conditions at the observation point and for anticipating any changes that may occur as the cloud system moves.

Being able to effectively interpret this encoding is crucial for pilots and aviation personnel, as it directly affects flight planning and safety considerations. Understanding the movement and position of significant weather phenomena helps in making informed decisions about routes and altitudes.
