A fixed-length group of bits representing the large data element handled as a unit by a computer. Word length is determined by the capacity of the CPU registers.

Category:Meteorology

An instrument which indicates the presence of dust particles in the atmosphere. Also spelled coniscope.

Category:Meteorology

In Jeffreys' classification, a wind for which the pressure force exactly balances the viscous force, in which the vertical transfers of momentum predominate.

Category:Meteorology

Area of a computer or other device where various logic and control elements are interconnected. Often a printed circuit board into which other circuit boards plug at right angles.

Category:Meteorology

A unit of pressure used principally in oceanography. One decibar (10' dynes/cm2) equals 0.1 bar. In the ocean, hydrostatic pressure in decibars very nearly equals the corresponding depth in meters.

Bar

A unit of pressure equal to 10' dyne per cm-' (101 barye), 1000 millibars. 29.53 inches of mercury.

Category:Meteorology

A method of streamflow routing which assumes that storage is a linear function of the weighted flow in the reach and is adaptable to a simple mathematical solution.

Category:Meteorology

The range through which the input may be varied without initiating a response. Usually expressed as a percentage of full-scale range.

Category:Meteorology

Same as luminous intensity.

Category:Meteorology

See river basin.

Category:Meteorology

The group of bits which a computer processes as a unit; often, 8 bits.

Category:Meteorology

A medium-sized instrument shelter. It is a white louvered box with a flat double to of and is mounted four feet above the ground on a four-legged stand.

Category:Meteorology

A hygrometer in which the sensitive element is a strand or strands of human hair, the length of which is a function of the relative humidity of the air.

Category:Meteorology

Same as atmospheric pressure.

Category:Meteorology

A rain gauge which indicates but does not record the amount of precipitation captured.

Category:Meteorology

An instrument for rapidly obtaining samples of airborne dust; a type of dust counter. Particles pass through a cylindrical chamber, are drawn at high velocity through a narrow slit, and then impinge upon a microscope cover glass located a short distance f ...

Category:Meteorology

A counterclockwise change in wind direction. Backing winds with height are indicative of cold air advection (CAA).

Category:Meteorology

See instrument error, observational error. random error, standard error, systematic error.

Category:Meteorology

A special form of the aspiration psychrometer. developed by Assmann, in which the thermometric elements are well shielded from radiation. Psychrometric measurements may be taken with the instrument in the presence of direct solar radiation.

Category:Meteorology

An instrument which determines the altitude of an object with respect to a fixed level. There are two general types of altimeters: (a) the pressure altimeter, which gives an approximate measure of altitude from a pressure measurement and an assumed standa ...
