Sanskrit hima, Latin hiems and Greek kheimṓn are cousins from one inherited root — though the branches disagree about whether it names the substance or the season. The Himalaya is hima-ālaya, the abode of snow, and it is the reason a Sanskrit snow-vocabulary exists at all in a largely subtropical language.
Latin nix, stem niv-, gives the Romance names — Neve, Nieves, Nevena. The Spanish Nieves is specifically Marian, from Our Lady of the Snows, and is a religious name rather than a nature name despite appearances.
The Slavic and Nordic languages, unsurprisingly, have the richest vocabulary here, distinguishing snow by texture, depth and age in ways that do not survive translation. Japanese yuki is among the most common elements in girls' naming.
What is worth noticing is the near-absence of snow-names from the equatorial traditions in this library, and their prominence in the Himalayan, Andean, Nordic and Central Asian ones. This is one of the few concepts in the Atlas where the geography of the names maps almost exactly onto the geography of the thing.
