Glaciogenic cloud seeding aims to

  • A.supply ice nuclei to a supercooled cloud that lacks them
  • B.supply condensation nuclei to a cloud that is fully glaciated
  • C.warm the cloud so that its droplets evaporate
  • D.increase the depth of the cloud by direct heating

Answer: A

Many supercooled clouds contain too few natural ice nuclei to glaciate efficiently. Adding artificial nuclei is intended to start the Bergeron process and convert liquid water into precipitation. The cloud's own nuclei are the limiting factor being supplied.
