Wind shear reduces precipitation efficiency chiefly by

  • A.preventing droplets from activating at the cloud base entirely
  • B.displacing condensate away from the updraught that produced it
  • C.raising the terminal velocity of the raindrops that form
  • D.increasing the number of condensation nuclei

Answer: B

Water carried downwind falls into air that is descending or subsaturated and evaporates. Shear also organises storms in ways that can raise efficiency, so the net effect is not always negative. Shear acts differently on a single cell and on a system.
