What is the symbol used for heavy intensity precipitation?

The symbol used to represent heavy intensity precipitation is indeed the plus sign. In meteorological symbols, the plus sign indicates that significant amounts of precipitation are occurring, falling at a heavy rate. This is crucial information for pilots and meteorologists, as understanding the intensity of precipitation can directly influence flight safety, routing decisions, and overall operational planning.

The use of this symbol aligns with the conventions outlined in aviation weather reporting systems, where clear and standardized symbols communicate critical weather information efficiently. By using the plus sign for heavy precipitation, it distinguishes this intensity level from lighter precipitation types, allowing for quick assessment of conditions that could affect aviation operations.

Awareness of such symbols is essential for those involved in aviation and meteorology to ensure accurate interpretation of weather data and to make informed decisions based on the weather conditions reported.
