Convection vs Advection - What's the difference?
convection | advection |
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.
(earth science, chemistry) The horizontal movement of a body of atmosphere (or other fluid) along with a concurrent transport of its temperature, humidity etc.
The transport of a scalar by bulk fluid motion.
