Convection caused by mechanical forces, such as those arising from air motion over a rough or sloping surface.  2, record 4, English, - forced%20convection

Record number: 4, Textual support number: 1 CONT

Convection... is a principal means of energy transfer. Distinction is made between free convection(gravitational or buoyant convection), motion caused only by density differences within the fluid; and forced convection, motion induced by mechanical forces such as deflection by a large-scale surface irregularity, turbulent flow caused by friction at the boundary of a fluid, or motion caused by any applied pressure gradient. Free and forced convection are not necessarily exclusive processes. On a windy day with overcast sky, the heat exchange between ground and air is an example of forced convection. On a sunny day with a little wind where the ground temperature rises, both kinds of convection take place.  3, record 4, English, - forced%20convection

The ratio of lateral entrainment velocity to plume-rise velocity of a smoke plume.  2, record 6, English, - entrainment%20coefficient

Record number: 6, Textual support number: 1 CONT

Smoke plumes that rise through the environment due to buoyancy or momentum become diluted with environmental air, where the rate of dilution is proportional to the rise rate of the plume. The entrainment coefficient is this constant of proportionality. This concept of lateral entrainment does not work well for convective thermals in the atmospheric boundary layer. One reason is that boundary layer thermals are part of a large overturning circulation involving the whole boundary layer during statically unstable conditions of free convection, rather than being thin currents of rising smokestack air.  2, record 6, English, - entrainment%20coefficient
