(convection) the transfer of heat through a fluid (liquid or gas) caused by molecular motion

(convection) (meteorology) the vertical movement of heat or other properties by massive motion within the atmosphere

Convection is the movement of molecules within fluids (i.e. liquids, gases) and rheids. It cannot take place in solids, since neither bulk current flows nor significant diffusion can take place in solids.

(Convection (meteorology)) Atmospheric convection is the result of a parcel-environment instability, or temperature difference, layer in the atmosphere. It is often responsible for adverse weather throughout the world.

(convection) The process of conveying something; The transmission of heat in a fluid or gas by the circulation of currents; The vertical movement of heat and moisture, especially by updrafts and downdrafts in an unstable air mass. ...

(Convection) A method of transferring heat by the actual movement of heated molecules, usually by a freestanding unit such as a furnace.

(Convection) Atmospheric motions in the vertical direction resulting from surface heating and the subsequent rising of warm air. This lifting mechanism is capable of generating the rising motions necessary for clouds and precipitation to form.

(Convection) Currents created by heating air, which then rises and pulls cooler air behind it. Also see radiation.

(convection) Fluid motion which results from the action of unbalanced buoyancy forces.

(Convection) The motion resulting in a fluid from the differences in density and the action of gravity. In heat transmission this meaning has been extended to include both forced and natural motion or circulation.

(Convection) The motion of fluid such as gas or liquid by which heat may be transported.

(Convection) Atmospheric motions that are predominantly vertical, resulting in vertical transport and mixing of atmospheric properties.

Convection heat transfer occurs when air passes over an object. Convection heating requires contact of the air flow with the solid part. Only the layer of the flow that is in contact with the part is actually transferring heat. ...

(Convection) The movement heat by currents in liquids or gases.

(Convection) Transfer of thermal energy via fluid currents (gases or liquids).

(Convection) The vertical transport of heat and/or moisture within the atmosphere. Thunderstorms are an example of moist convection.

(convection) a process by which heat energy may be circulated in gases and liquids. As the material is heated, it expands, becomes less dense, and rises. Cooler material moves in to take its place. Meanwhile, the heated material cools off, becomes more dense, and sinks. ...

(convection) A cooking method that circulates hot air around food to cook it faster than conventional ovens.

Convection is the motion of air upward, caused by heating. For example a hot parking lot can heat the air above it and this heating causes the air to rise.

(Convection) Mass motions within a fluid resulting in transport and mixing of the properties of that fluid.

(convection) transfer of thermal (heat) energy by the flow of liquids or gases. (For example, convection is responsible for making macaroni rise and fall in a pot of heated water. The warmer portions of the water are less dense and therefore, they rise. ...

(Convection) Transmission of energy (heat/sound) from one place to another by movement of a fluid such as air or water.

(convection) vertical movement of heat or air due to buoyancy. (Convection)

(convection) a form of heat transfer effected by the flow of fluid across an object of a different temperature. If the object is warmer, the heat will transfer from the object to the liquid or gas; if the object is cooler, the heat will transfer from the liquid or gas to the object.

(Convection) Heat transfer by currents that flow from a warm surface to a colder one.
