陽炎

• Reading: かげろう
• Romaji: kagerou

• Pronunciation: /ka.ɡe.ɾoː/

Meaning

Heat haze; mirage; shimmer. The wavering distortion of light near hot surfaces, especially roads or sand on a summer day.

A noun describing the optical phenomenon caused by light refracting through air heated by a hot surface, making distant objects appear to shimmer or float. In classical Japanese poetry and literature, 陽炎 is associated with early spring and the transience of ephemeral things. Distinguished from 蜻蛉 (also read かげろう), which refers to dragonflies and mayflies — context determines meaning.

2. 砂漠に陽炎が揺れ、遠くにオアシスが見えるような錯覚を覚えた。 The heat haze shimmered over the desert, creating the illusion that an oasis was visible in the distance.
3. 陽炎の中に古い街並みが溶けていくような、不思議な風景だった。 It was a strange and beautiful scene, as if an old townscape were dissolving into the heat haze.
