What does "SN" stand for in weather reports?

In weather reports, "SN" is an abbreviation that specifically stands for snow. This code is part of the METAR (Meteorological Aerodrome Report) format used internationally by aviation meteorologists to provide essential weather data to pilots and air traffic controllers. In these reports, different weather phenomena are denoted by standardized abbreviations to ensure clarity and ease of communication in the aviation industry.

The other choices provided do not correspond to the "SN" abbreviation. Strong winds would typically be indicated by other specific terms or phrases, while heavy rain is denoted by "RA." The term "slow clouds" does not have a recognized abbreviation in weather reporting. Therefore, understanding that "SN" corresponds to snow helps in gathering pertinent information about current weather conditions that can influence flight safety and operational decisions.
