Wake
type: Class
subclass of: Turbulence
comment: The region of turbulence immediately to the rear of a solid body in motion relative to a fluid

ZombieTurbulence
type: Class
subclass of: Perturbation
subclass of: Turbulence
comment: The turbulent perturbations of temperature remaining in a stable boundary layer after all turbulent motions have died out.

Turbulence
type: Class
subclass of: Fluctuation
subclass of: FluidPhenomena
comment: Irregular fluctuations occurring in fluid motions.

MechanicalTurbulence
type: Class
subclass of: Turbulence
comment: Turbulence produced by shear flow.

LargeReynoldsNumberFlow
type: Class
subclass of: Flow
comment: The behavior of a fluid with a Reynolds number typically greater than 1E4 to 1E6, which usually occurs within the atmosphere. The main property of such flows is a constant friction stress within the surface layer that depends only on relative roughness but not on the Reynolds number itself. Thus, molecular viscosity and qualities occurring in flow descriptions that are dependent on the Reynolds number may be totally ignored.

FrontalInversion
type: Class
subclass of: Inversion
subclass of: Restriction
  on property: hasPhenomena
  all values from: Front
comment: A temperature inversion (temperature rising with height) in the atmosphere, encountered upon vertical ascent through a sloping front (or frontal zone).

Inversion
type: Class
subclass of: FluidPhenomena
subclass of: Restriction
  on property: hasQuantity
  all values from: TemperatureGradient
comment: In meteorology, a departure from the usual decrease or increase with altitude of the value of an atmospheric quantity; also, the layer through which this departure occurs (the inversion layer), or the lowest altitude at which the departure is found (the base of the inversion).

KelvinHelmholtzInstability
type: Class
subclass of: FluidInstability
comment: An instability of the basic flow of an incompressible inviscid fluid in two parallel infinite streams of different velocities and densities.

Absolute Instability
type: Class
subclass of: FluidInstability
subclass of: Restriction
  on property: hasState
  has value: Superadiabatic
comment: state of a layer of atmosphere when it has superadiabatic lapse rate of temperature

ConvectiveInstability
type: Class
subclass of: FluidInstability
comment: An instability due to the buoyancy force of heavy fluid over light fluid overcoming the stabilizing influence of viscous forces.

ConditionalInstability
type: Class
subclass of: FluidInstability
comment: The state of a layer of unsaturated air when its lapse rate of temperature is less than the dry-adiabatic lapse rate but greater than the moist-adiabatic lapse rate.

FreeInstability
type: Class
subclass of: FluidInstability
comment: The state of a layer of unsaturated air when its lapse rate of temperature is less than the dry-adiabatic lapse rate but greater than the moist-adiabatic lapse rate.

StaticStability
type: Class
subclass of: FluidInstability
comment: The ability of a fluid at rest to become turbulent or laminar due to the effects of buoyancy.
