Air heated by a space heater rises and is replaced by cool air, creating a convection current that circulates hot air throughout a room.


1. The act or process of conveying; transmission.
2. Physics
a. Heat transfer in a gas or liquid by the circulation of currents from one region to another.
b. Fluid motion caused by an external force such as gravity.
3. Meteorology The transfer of heat or other atmospheric properties by massive motion within the atmosphere, especially by such motion directed upward.

[Late 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.]
