What's the difference between convection and weather?

Convection


Definition:

  • (n.) The act or process of conveying or transmitting.
  • (n.) A process of transfer or transmission, as of heat or electricity, by means of currents in liquids or gases, resulting from changes of temperature and other causes.

  • (v. t.) To place (a hawk) unhooded in the open air.
  • (v. i.) To undergo or endure the action of the atmosphere; to suffer meteorological influences; sometimes, to wear away, or alter, under atmospheric influences; to suffer waste by weather.
  • (a.) Being toward the wind, or windward -- opposed to lee; as, weather bow, weather braces, weather gauge, weather lifts, weather quarter, weather shrouds, etc.
