Turbulence Parameterizations

  • Determines how the meteorological data are processed to compute the horizontal and vertical turbulence
  • The results shown here provide some rationale for the the default turbulence settings
  • Turbulence options are intended to provide some flexibility when using different input meteorological data
  • One use shown later is in the development of a physics ensemble
