Document Summary
Air density mass per unit volume of earth"s atmosphere; decreases with increasing altitude and changes with variation in temperature of humidity. Air pressure/atmospheric pressure the force exerted onto a surface by the weight of air. Adiabatic lapse rate the rate at which atmospheric temperature decreasing with increasing altitude in conditions of thermal equilibrium. Dry adiabatic lapse rate rate of temperature decrease with altitude for a parcel or dry or unsaturated air rising under adiabatic conditions. Wet adiabatic lapse rate when the air is saturated with water vapor. Convection the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder denser material to sink under the influence of gravity; results in the transfer of heat. Convection cell a self-contained convective zone in a fluid in which upward motion of warmer fluid in the center is balanced by downward motion of cooler fluid at the periphery.
