1. n. The act or process of conveying or transmitting.

Definition of Convection

1. Noun. The process of conveying something. ¹

2. Noun. (physics) The transmission of heat in a fluid or gas by the circulation of currents. ¹

3. Noun. (meteorology) The vertical movement of heat and moisture, especially by updrafts and downdrafts in an unstable air mass. The terms convection and thunderstorm are often used interchangeably, although thunderstorms are only one form of convection. Towering cumulus clouds are visible forms of convection. ¹

Medical Definition of Convection

1. Transmission of energy or mass by a medium involving movement of the medium itself. The circulatory movement that occurs in a fluid at a nonuniform temperature owing to the variation of its density and the action of gravity. (12 Dec 1998)
