意味

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.
