1. the transfer of heat through the movement of heated liquids or gases
Usage: physics; meteorology
2. the circular movement of air or liquid caused by heating

Examples

• Convection currents in the atmosphere create wind patterns.
• The soup heated unevenly due to convection in the pot.
• Convection ovens circulate hot air for faster cooking.
• Ocean convection helps distribute heat around the planet.
• The radiator works by convection, warming the air around it.
• Convection is one of three main methods of heat transfer.
