When reporting weather conditions, what does the abbreviation "SH" signify?

The abbreviation "SH" signifies "showers" in weather reporting. This term is used in meteorological contexts to indicate intermittent rain or precipitation that occurs in varying intensities. Showers are often characterized by their sudden onset and can be brief but heavy, differing from steady rain. Understanding this abbreviation is crucial for aviation and meteorology, as it helps pilots and meteorologists communicate specific weather phenomena effectively, enabling safer navigation and planning during flight operations. In contrast, the other options represent different weather conditions or phenomena that do not correspond with the "SH" abbreviation.
