How are separate weather phenomena represented in the reporting system?

The representation of separate weather phenomena in the reporting system is done with individual present weather groups for each phenomenon. This approach allows for clear and precise communication of multiple weather conditions that may be occurring simultaneously. Each phenomenon has its specific coding that delivers information about the type of weather observed, ensuring that pilots and meteorologists have detailed data for assessing flight safety and operational conditions.

Using separate groups helps avoid ambiguity that might arise from combining different weather phenomena into a single code, thereby enhancing understanding of the prevailing conditions. This method aligns with standard practices in aviation weather reporting, where clarity and precision are crucial for effective decision-making. Other options do not provide the level of specificity needed for accurate weather reporting.
