Which quantity does the freezing level give on a sounding?

  • A.The height at which the dew point curve crosses zero degrees, indicating where ice crystals begin to form
  • B.The cloud base
  • C.The height of the melting layer, which lies several hundred metres below the level of the zero degree isotherm
  • D.The height at which the temperature curve crosses zero degrees

Answer: D

The freezing level is where the environmental temperature curve crosses the zero degree isotherm, and it determines whether precipitation reaches the ground as rain or snow. The melting layer detected by radar lies a few hundred metres below it, since falling snow takes time to melt completely, so the last option describes a real distinction rather than an error. The shared properties explain why these belong to one family, and the differences explain why more than one exists.
