ConvectivePlume
type: Class
subclass of: Restriction
  on property: hasPhenomena
  all values from: Convection
subclass of: Plume
comment: A buoyant jet stream in which the buoyancy is supplied steadily from a point source; the buoyant region is continuous.

Fanning
type: Class
subclass of: Plume
comment: A pattern of smokestack plume dispersion in a statically stable atmosphere, in which the plume spreads out in the horizontal like an oriental fan and meanders about at a fixed height with little vertical spread.

Lofting
type: Class
subclass of: Convection
comment: The phenomenon where the upper part of a smoke plume diffuses more rapidly upward than the bottom part diffuses downward. This generally occurs when the boundary layer near the ground is more stable than it is aloft. Compare coning, fanning, looping.

Plume
type: Class
subclass of: SuspendedSubstance
subclass of: Restriction
  on property: hasState
  has value: Fluid
comment: Buoyant jet in which the buoyancy is supplied from a point source; the buoyant region is continuous. 2. A mostly horizontal (sometimes initially vertical) stream of pollutant that is being blown downwind from a smokestack.

StackEffect
type: Class
subclass of: Convection
comment: An effect due to heat sources within a local exhaust enclosure (stack) producing convective air currents with vertical velocities proportional to the rate of heat transferred to the surrounding air and to the height of rise of the heated air.

WestEastTransport
type: Class
subclass of: Transport
comment: The eastward flux of mass, momentum, heat, moisture or any other property of a fluid by mean motion or by correlation with the eastward component of motion, that is, eddy flux.

Buoyancy
type: Class
subclass of: Phenomena
comment: That property of an object that enables it to float on the surface of a liquid, or ascend through and remain freely suspended in a compressible fluid such as the atmosphere.

Convection
type: Class
subclass of: Phenomena
comment: In general, mass motions within a fluid resulting in transport and mixing of the properties of that fluid. Convection, along with conduction and radiation, is a principal means of energy transfer.

Deposition
type: Class
subclass of: Phenomena
comment: Phenomena by which traces gases or particles are transferred from atmosphere to a surface.

SlantWiseConvection
type: Class
subclass of: Convection
comment: A form of convection driven by a combination of gravitational and centrifugal forces.

Advection
type: Class
subclass of: Phenomena
subclass of: Restriction
  on property: hasState
  has value: Fluid
subclass of: Restriction
  on property: hasPhenomena
  all values from: Transport
comment: The process of transport solely by the mass motion (velocity field); also, the rate of change of the value of the advected property at a given point.

VorticityAdvection
type: Class
subclass of: Advection
comment: Advection of vorticity by the total wind or force.
