- Convection is defined as the act of moving, transmitting or conveying.
An example of convection is the moving of liquid.
- a transmitting or conveying
- the mass movement of portions of a fluid within the fluid, caused by differences in density
- the transfer of heat by its absorption by a fluid at one point, followed by motion of the fluid and rejection of the heat at another point
Origin of convectionClassical Latin convectio from past participle of convehere, to bring together from com-, together + vehere, to carry, bear
- The act or process of conveying; transmission.

- Meteorology The transfer of heat or other atmospheric properties by massive motion within the atmosphere, especially by such motion directed upward.
Origin of convectionLate Latin convectiō convectiōn- from convectus past participle of convehere to carry together Latin com- com- Latin vehere to carry ; see wegh- in Indo-European roots.
Air heated by a space heater rises and is replaced by cool air, creating a convection current that circulates hot air throughout a room.
- The process of conveying something.
- (physics) The transmission of heat in a fluid or gas by the circulation of currents.
- (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.
From Latin convectionem, from convectio (“act of carrying”), from convect-, past participle of convehere (“to carry together”), combination of com- and vehere.
