What type of precipitation does the abbreviation FZRS represent?

The abbreviation FZRS stands for Freezing Drizzle. This term specifically describes a weather phenomenon where light rain falls and freezes upon contact with cold surfaces, leading to the formation of a thin coating of ice. It differs from regular drizzle in that the droplets are larger and when they freeze, they create slick and hazardous conditions on roadways and other surfaces.

This type of precipitation is particularly important for aviation and ground travel, as it can lead to significant issues such as reduced traction and visibility. The freezing nature of this drizzle is what distinguishes it from snow, freezing rain, and heavy rain. Each of those forms of precipitation has its specific characteristics and implications for weather forecasting and safety, but FZRS is specifically about light drizzle that becomes freezing upon contact. Understanding this distinction is crucial for safe operations in aviation and for ground transportation.
