1. One of several accepted measures of central tendency, physically analogous to “center of gravity. ”
Pertaining to a set of numbers x1, x2,. . . , xn, the arithmetic mean, usually denoted by the symbol , is the sum x1 + x2 +. . . + xn divided by n. Since the word “mean” is also applied to other measures of central tendency, such as weighted means, geometric means, and harmonic means, the adjective “arithmetic” is used for clarity. However, when used without further qualification, the term “mean” is understood as arithmetic mean. Compare geometric mean. 2. Pertaining to a random variable, same as expected value.

A function of precipitation and temperature designed by W. Gorczyński to represent the relative lack of effective moisture (the aridity) of a place. It is given by (latitude factor) × (temperature range) × (precipitation ratio). The latitude factor is the cosecant of the latitude (taken as 3. 0 for 0°–4°). The temperature range is the difference (°F) between the means of the hottest and coldest months. The precipitation ratio is the difference between the highest and lowest annual totals (adjusted to a 50-year record) divided by the average. The value of this coefficient is about 100 in the middle of the Sahara; in the United States it ranges from 70 at Bagdad, California, to 2 at Eureka, California.

The degree to which a climate lacks effective, life-promoting moisture; the opposite of humidity, in the climate sense of the term. The overall concept of aridity versus humidity is coming to be known as precipitation effectiveness. Two basic approaches have been made. The first, used by W. Köppen and modified by Bailey, does not openly define aridity, but rather assigns delimiting values of annual precipitation (treated with regard to distribution and temperature) to separate a dry climate from other types. The second approach actually prescribes a measure of aridity or precipitation effectiveness and uses these values as a primary parameter of classification. Of this type are Thornthwaite's precipitation- effectiveness index and moisture index, E. De Martonne's index of aridity, W. Gorczyński's aridity coefficient, Lang's moisture factor, and Ångström's humidity coefficient.
Industry:Weather
1. A region with insufficient moisture where evaporation exceeds precipitation. 2. Sometimes used synonymously with equatorial dry zone.

A data collection and location system installed on POES satellites. Argos, provided by France, allows environmental data sensed by remote platforms, fixed or moving, to be collected by POES satellites and retransmitted to ground processing stations.
Industry:Weather
Noble gas, symbol Ar, of atomic mass 40, that composes 0. 93% by volume of dry air. Argon is constantly produced in the earth's crust from the radioactive decay of 40K and is subsequently released into the atmosphere. It is the most abundant of the inert gases in the atmosphere, and the third most abundant of all atmospheric constituents. Argon was discovered by Rayleigh and Ramsay in 1894.
Industry:Weather
The area within the cone of depression of a discharging well or the cone of impression of a recharging well.
Industry:Weather
1. (Formerly called North Frigid Zone. ) Geographically, the area north of the Arctic Circle (66°34′N). 2. (Same as tundra. ) Biogeographically, the area extending northward from the arctic tree line to the “limit of life. ”
It is also used for the level above the timber line in mountains.
