Which symbol denotes moderate intensity of precipitation?

The symbol indicating moderate intensity of precipitation is actually a plus sign (+). This symbol is used to denote moderate rainfall or snowfall in meteorological reports and forecasts. In this context, it signals the significance of the precipitation, informing pilots and meteorologists about its potential impact on flying conditions.

The absence of a symbol does not provide information about the intensity of precipitation. It typically indicates that there is no precipitation happening at the time of the observation. Other symbols, such as a minus sign (-) or VC (which denotes rain in the vicinity), also serve specific purposes but do not represent moderate intensity.

Understanding these symbols is crucial for interpreting METAR and TAF reports accurately, as they provide essential information regarding weather conditions that can affect aviation safety and operations.
