6.9: Air Masses Unit 6: Meteorology March 13, 2012 Sanders

Convection Convection occurs when a liquid or gas is in contact with a solid body at a different temperature and is always with the motion of the liquid or gas. Convection transfers heat through the exchange of hot and cold molecules. May 21, 2019 Unit 6: Meteorology

Conduction Conduction requires physical contact between the bodies or portions of bodies exchanging heat. Conduction is the transfer of heat in a solid object. May 21, 2019 Unit 6: Meteorology

Radiation Radiation does not require contact between bodies. Radiation is the transfer of heat by electromagnetic radiation. May 21, 2019 Unit 6: Meteorology

Heat Transfer May 21, 2019 Unit 6: Meteorology

Air Masses Air with the same temperature, pressure, and humidity called air masses. Air Masses have two distinguishing qualities; its temperature and its humidity. May 21, 2019 Unit 6: Meteorology
