Definition(s):

  1. (n) the transfer of heat through a fluid (liquid or gas) caused by molecular motion
  2. (n) (meteorology) the vertical movement of heat or other properties by massive motion within the atmosphere

Usage(s):

  1. As connoisseurs of their local dish, Beijingers love to debate the merits of convection roasters over peach-wood ovens, or to quibble over sauce recipes.
  2. Most building insulation simply reduces heat transfer through conduction and convection.
  3. Adjacent cylinders rotate in opposite directions in the 250,000-mile-deep solar convection zone and gradually migrate toward the equator.
