Origin

The character 雰 combines the rain radical 雨 at the top with 分 at the bottom. The rain component makes sense for the meaning since atmosphere and fog are both weather-related phenomena involving moisture and air around us. The 分 component serves as a sound hint, telling you roughly how to pronounce the character (フン), rather than contributing to its meaning. Together, the rain imagery paired with this phonetic guide creates a character that captures the concept of the invisible atmospheric layer surrounding us.
