Coded groups in military forecasts may include which of the following?

Coded groups in military forecasts typically encompass specific aviation-related weather phenomena, which include significant factors affecting flight safety and operations. The inclusion of turbulence forecasts from surface to 10,000 feet is essential for pilots and flight planners, as turbulence can greatly impact aircraft performance and passenger comfort. This information is crucial for pre-flight planning and in-flight decision-making.

The other options do not fit within the typical coded group context found in military forecasts. For instance, while visibility metrics under 1 mile and cloud cover percentage are important weather elements, they are not usually presented in coded groups for military forecasts, which focus on more critical operational factors. Ground temperature readings, while significant in other contexts, do not specifically pertain to the immediate flight operations and safety that coded groups primarily address.
