When the lapse rate of a column of air is greater than the dry adiatabtic lapse rate. The term absolute is used because this applies whether or not the air is dry or saturated. It is also the zero point of the Kelvin Temperature Scale. The process in which incident radiant energy is retained by a substance. Absorbed energy results in surface heating.
Objects take heat and reradiate it at different wavelengths.
The flat, gently sloping or nearly level region of the sea floor. A thermodynamic change of state in a system in which there is no transfer of heat or mass across the boundaries of the system. In this process, compression will result in warming and expansion will result in cooling. Examples include heat and moisture advection. An example is Arctic Sea Smoke, a form of sea fog.
