Atmospheric chemistry
Vertical mixing
Chemistry; Atmospheric chemistry
The movement of air in a vertical direction usually caused by differences in temperature and density.
Effusion
Chemistry; Atmospheric chemistry
The movement of gas molecules through an opening that has relatively large holes.
Dewpoint
Chemistry; Atmospheric chemistry
The temperature at which air is cooled enough to reach its saturation point (100% humidity) for a given volume of water vapour in the air. If the air cooling occurs because of adiabatic expansion, ...
Atmosphere
Chemistry; Atmospheric chemistry
The sum total of all the gases surrounding the Earth, extending several hundred kilometres above the surface in a mechanical mixture of various gases in fluid-like motion. The permanent constituents ...
Kinematic viscosity
Chemistry; Atmospheric chemistry
The ratio of absolute viscosity--or a fluid's resistance to flow--to the density of that fluid; this is commonly measured by determining the time it takes a liquid to travel through a capillary under ...
Polar vortex
Chemistry; Atmospheric chemistry
This is a phenomenon that occurs during the polar winter in which stratospheric air moves in a circular motion, with a volume of relatively still air in its center. The temperature in the vortex is ...
Radioactive decay
Chemistry; Atmospheric chemistry
The spontaneous breakdown of certain kinds of atomic nuclei into one or more nuclei of different elements, involving the release of energy and subatomic particles such as neutrons.
