Consider the following statements about precipitation efficiency.
1. Dry air below cloud base reduces it through evaporation.
2. Strong wind shear can carry condensate away from the updraught.
3. It is close to one hundred per cent in most convective clouds.

  • A.3 only
  • B.1 only
  • C.All of them
  • D.1 and 2 only

Answer: D

The first two are correct and are the main losses. The third is far too optimistic, since a large fraction of the condensed water in many convective clouds never reaches the ground at all. Losses to evaporation and to shear are both substantial.
