entrainment - 1. In meteorology, the mixing of environmental air into a preexisting organized air current so that the environmental air becomes part of the current; the opposite of detrainment.
Entrainment - The act of air being drawn into a cloud from the non-cloud environment.
Entropy - The measure of the randomness in a system. Also, the amount of thermal energy that is unavailable to do work.
Entrainment Zone
A shallow region at the top of a convective boundary layer where fluid is entrained into the growing boundary layer from the overlying fluid by the collapse of rising convective plumes or bubbles.

Entrainment The mixing of environmental air into a preexisting air current or cloud so that the environmental air becomes part of the current or cloud.
Entrainment - The infiltration of surrounding air into a vertically nonmoving air column. For example, the influx of cool, dry air into the downdraft of a cumulonimbus cloud; a process that acts to intensify the downdraft.
ENTRAINMENT - The drawing of air or moisture into a weather system.
EQUILLIBRIUM LEVEL - The point in the atmosphere when a rising air parcel is the same temperature as the surrounding air.
ENTRAINED / ENTRAINMENT- Refers to the drawing in of moisture (or lack of moisture) into a system. Dry air entrainment into the mid levels of a thunderstorm can enhance the potential for damaging wind gusts.
