frost
霜 centers on frozen atmospheric moisture that forms icy crystals: frost. It is the visible white coating that appears on cold surfaces.
霜 combines 雨 (rain, atmospheric phenomena) with 相, which likely contributes the sound and may suggest the appearance of frost as a mutual or paired formation of ice crystals.
Rain 雨 falls and meets the cold ground, forming a mutual 相 pattern of frost crystals. Picture rain freezing into a delicate white coating.
For ソウ, imagine frost forming on a soulful winter morning: soul -> ソウ, and the frost covers everything with icy beauty.
