What 霥 means
It has two historical weather readings, not one fixed gloss.
A dictionary’s phrase “thunder sound” points to storm noise; a separate character study places 霥 in a historical variant chain for misty rain and concealment. The source and surrounding words decide which reading fits.
What is 霥’s historical record?
Its earliest documented record is in a Song-era rhyme dictionary.
The dictionary 集韻, completed in 1039, glosses 霥 as 靁聲, “thunder sound.” A rhyme dictionary grouped words by sound so readers could consult pronunciations, definitions, and variant forms.
A separate historical account links 霥 with 濛 and 蒙 in variant uses involving fine rain and covering. This is a textual relationship, not a license to swap the characters in modern writing.
What should I read into 霥 if someone sends it?
Ask which source or reading they intend.
By itself, 霥 cannot tell you whether the sender means the thunder gloss or the rain-and-covering tradition. If it appears in a dictionary quotation, follow that entry’s explanation.
If its strokes look a little different on another screen, the font is drawing a text character; that alone does not make it 濛 or 蒙. Those are separate characters, not alternate font renderings of 霥.
Archival or lexicographic when quoted; alone, it reads like a reference to an unusual character.
Don’t assume thunder if the surrounding text points to fine rain or covering.

1Why does 霥 show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
