con·vec·tion (k n-v k shn)n. 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 convecti  , convectin-, from convectus, past participle of convehere, to carry together : Latin com-, com- + Latin vehere, to carry; see wegh- in Indo-European roots.]con·vec tion·al adj.con·vec tive adj.con·vec tive·ly adv. |   Air heated by a space heater rises and is replaced by cool air, creating a convection current that circulates hot air throughout a room. |
convection [kənˈvɛkʃən]
n
1. (Physics / General Physics) a process of heat transfer through a gas or liquid by bulk motion of hotter material into a cooler region Compare conduction [1]
2. (Earth Sciences / Physical Geography) Meteorol the process by which masses of relatively warm air are raised into the atmosphere, often cooling and forming clouds, with compensatory downward movements of cooler air
3. (Earth Sciences / Geological Science) Geology the slow circulation of subcrustal material, thought to be the mechanism by which tectonic plates are moved
[from Late Latin convectiō a bringing together, from Latin convehere to bring together, gather, from vehere to bear, carry]
convectional adj
convective adj
| convection (kn-vkshn) Current in a fluid caused by uneven distribution of heat. For example, air on a part of the Earth's surface warmed by strong sunlight will be heated by contact with the ground and will expand and flow upward, creating a region of low pressure below it; cooler surrounding air will then flow in to this low pressure region. The air thus circulates by convection, creating winds. See Note at conduction. |
convection
the vertical movement of elements of the atmosphere. Cf. advection.
