The air flow produced about a high pressure center by the combination of two forces: the pressure gradient accelerating the air away from the center and the Coriolis force acting inward. Anticyclonic flows are clockwise in the northern hemisphere and counterclockwise in the southern hemisphere.
Industry:Chemistry; Weather
The amount of heat that is transferred across a surface of unit area in a unit of time.
Industry:Chemistry; Weather
The amount of time a substance can remain in a reservoir. The reservoir can be aquatic, atmospheric, or terrestrial. In atmospheric chemistry an example of reservoir time would be the amount of time NO<sub>x</sub> can remain in the atmosphere before being removed by deposition or chemical reactions.
Industry:Chemistry; Weather
The area where the temperature in the troposphere no longer decreases, indicating the boundary between the troposphere and the stratosphere.

The axis of Earth's rotation tilted all year perpendicular to the plane of the Earth's orbit around the sun. The angle is 23. 5°. Because of this angle on December 22 the northern hemisphere has its winter solstice and the southern hemisphere has its summer solstice, and the latitude 23. 5°S is the farthest point south at which directs sunlight hits. On June 22 the northern hemisphere has its summer solstice and the southern hemisphere has its winter solstice, and the latitude 23. 5°N is the farthest point north that hit be direct sunlight hits. An animation illustrates this. ,
Industry:Chemistry; Weather
The bacteria assisted conversion of molecular nitrogen, N<sub>2</sub>, to ammonia.
Industry:Chemistry; Weather
The biological and geographic study of the properties of carbon's chemical properties in relation to gases in the atmosphere. Models that study this often incorporate atmospheric carbon dioxide, carbonates in the ocean, organic carbon, and dissolved inorganic carbon in an attempt to determine the temporal characteristics of the planet's carbon cycle.

The boundary between the stratosphere and the mesosphere. It occurs at a height in the atmosphere of approximately 50 kilometers; however this depends on latitude. The atmosphere is characterized by a decrease in pressure with respect to increased altitude. More importantly, regions within the atmosphere like the troposphere, stratosphere, and mesosphere are distinguishable because of distinct temperature gradients with relatively well-defined starting and ending points. The stratopause is the highest portion of the stratosphere, with a temperature of approximately 0 degrees Celsius; the stratopause can also be described as the warmest region between the mesosphere and the stratosphere.
Industry:Chemistry; Weather
The branch of mineralogy that deals with the study of rocks and their composition.
Industry:Chemistry; Weather
The breaking down (mineralization) of organic matter to produce reduced or oxidized products such as NH<sub>3</sub>, NO<sub>x</sub> and CO<sub>2</sub> (g) and their subsequent release into the atmosphere; however, much of these decomposition products remain in the soil.
