Which check is applied when two methods disagree about the vertical motion?

  • A.Adoption of whichever result has the larger magnitude since errors generally act to reduce the value
  • B.Comparison with the observed cloud and precipitation
  • C.Recomputation using a finer vertical spacing until the two derived profiles converge on one another
  • D.Averaging the two results

Answer: B

Satellite imagery and radar provide an independent indication of where air is actually rising, so comparing the diagnosed field with the observed cloud shield is the natural arbiter. Averaging two results of unknown reliability has no justification, and there is no reason to suppose errors act systematically in either direction. Confronting a diagnostic with an independent observation is a sound general principle. Most errors here come from carrying a result across from a neighbouring case where it does not hold.
