Lightning is more frequent in continental than in maritime convection chiefly because

  • A.continental updraughts are stronger and support more graupel
  • B.maritime clouds contain no ice crystals whatsoever
  • C.the sea water beneath conducts the charge away
  • D.salt particles in the air prevent charge separation

Answer: A

Higher droplet concentrations and stronger updraughts carry more liquid water above the freezing level. The resulting graupel production is what drives the non-inductive charging. Aerosol and dynamics both contribute to the contrast.
