Stable Air

  • poor low level visibility
  • stratus type cloud
  • steady precipitation
  • steady winds which can change markedly with height
  • smooth flying conditions
  • steep lapse rate
  • small temperature lapse rate

Unstable Air

  • good visibility (except in precipitation)
  • cumulus or cumulonimbus clouds
  • showery precipitation
  • gusty winds
  • moderate or severe turbulence
  • shallow lapse rate
  • high temperature lapse rate
