PL is the meteorological code for what type of precipitation?

The meteorological code "PL" stands for "ice pellets," which are a type of precipitation that forms when raindrops freeze before they hit the ground, creating small, round pellets of ice. Ice pellets typically occur when there is a layer of warmer air above a sub-freezing layer close to the surface, which allows falling snowflakes to melt partially before refreezing into these pellets as they descend through the colder air.

This code is important for meteorologists, pilots, and others who need to understand weather conditions and how precipitation types can impact aviation safety and ground operations. Understanding such designations ensures effective communication regarding weather phenomena and can significantly influence decision-making in flight planning and operations.

Other options do not correspond to established meteorological codes, with none of them indicating a recognized form of precipitation. This highlights the significance of proper meteorological terminology and coding in aviation and weather forecasting.
