Circulation pattern developed under influence of regional or local topography that occur on scales of hundreds kilometres.

Comes from sun as short-wave radiation in the form of visible light.

Heat transfer by direct physical contact of air and earth .

Process initiated by the rising of warm air and the sinking of cold air

Condensation releases latent heat in the parcel, thus the cooling rate of the parcel slows, so called _____.

It is determined by the temperature difference between an air parcel and the air surrounding

A condition when the environmental lapse rate is less than the adiabatic lapse rate (cools at less than 9.8°C/1000 m)

It is important as the dividing line between stable and unstable conditions. It is when the environmental lapse rate is the same as the dry adiabatic lapse rate.

It occurs when air temperature increases with altitude.

A type of plume where stream of pollutant undergoes rapid mixing.

Related to clear skies, light winds, and stable atm. It reflect the relative uniformity of air masses.

It describes the transport and diffusion of a gas (or particle) from a source to a receptor according to stability class and other parameterized characteristics of the atmosphere.

Type of plume created when atmospheric conditions (inversion layer) are stable above the plume and unstable below (superadiabatic).
