  short Explanation:
  cb = Cumulonimbus (Thunderstorm cloud)
      cb-cal = Cumulonimbus Calvus (without amboss)
      cb-inc = Cumulonimbus Incus (with amboss)
  cu = Cumulus
      cu hum = Cumulus humilis (smallest one, only at fair, nice weather)
      cu med = Cumulus mediocris (middle)
      cu con = Cumulus congestus (the largest one, pre-stage of Cumulonimbus)
ns = Nimbostratus (Rain cloud)
  st = Stratus
  sc = Stratocumulus
  ac = Altocumulus
