A common design in operational orographic programmes is to

  • A.seed only after precipitation has already begun
  • B.run ground generators upwind during suitable synoptic conditions
  • C.seed every cloud that passes regardless of conditions
  • D.release agent above the cloud from high altitude aircraft

Answer: B

Criteria on temperature, wind direction and liquid water govern when generators are lit. The upslope flow then carries the agent into the supercooled part of the cap cloud. Wind direction determines whether the plume reaches the target.
