A man-made structure, such as a weir, bridge, dam, etc. , that serves as a control for a stream gauging station by stabilizing the rating curve.
Industry:Weather
A geologic basin in which, due to the presence of a confining layer, groundwater is stored at a pressure greater than hydrostatic pressure.
Industry:Weather
An aquifer in which the piezometric surface is above its upper boundary.
Industry:Weather
A water-carved channel or gully in arid country, usually rather small with steep banks, that is dry most of the time due to infrequent rainfall.
Industry:Weather
Hydrocarbons based on the structure of benzene, characterized by a very stable, unsaturated ring. Aromatics make up a sizeable fraction of the hydrocarbons emitted from automobiles, and their high reactivity contributes to local smog formation.
Industry:Weather
Formation of a layer of relatively large particles at the surface of a deposit due to the removal of finer sediment particles by fluid erosion. The armoured layer generally resists further erosion.
Industry:Weather
A weather forecast for a specified geographic area; usually applied to a form of aviation weather forecast (to distinguish it from terminal forecast, route forecast, and flight forecast).

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.
