What is the purpose of a proximity qualifier in weather reporting?

The purpose of a proximity qualifier in weather reporting is to specify the vicinity of observed weather phenomena. This term is used to inform the observer or recipient about the location of significant weather events in relation to the reporting station. For instance, when a report includes a proximity qualifier, it specifies whether a weather event, like precipitation or thunderstorm activity, is occurring nearby or at a certain distance from the observer's location. This helps in interpreting the potential impact of the weather on the area surrounding the reporting station, enhancing situational awareness for both meteorologists and the public.

In contrast, the other options refer to different aspects of weather reporting. Temperature is generally reported as a specific numerical value, while wind direction is given in degrees or as a cardinal direction without the use of a proximity qualifier. Humidity levels are typically expressed as a percentage, indicating the moisture content in the air, but do not involve specifying the vicinity of weather phenomena.
