英文释义

名词 n.
  1. Birdsong by a large number of birds occurring in the early morning.
    — But the music of the spring-tide is past; the cuckoo is no longer vocal; the dawn-chorus is silent; summer has stilled the voices that but lately trilled so tirelessly, and, until another spring arrives, hedgerow and spinney will not again resound with the singing of the birds.
  2. Radio interference sometimes experienced at sunrise.
    — [T]he dawn chorus usually has a characteristic chirpy sound, but at times changes into a hiss not unlike tube noise. […] Several investigators, including the author, have at times noticed a tendency for the dawn chorus to change intensity for a short period immediately following some lightning strokes. This may indicate a change in propagation conditions due to the electromagnetic or ionization effect of the strokes.
