A scale of yellows, greens, and blues for recording the color of sea water, as seen against the white background of a Secchi disk.

Category:Meteorology

In general, solar radiation received at the earth's surface. Contracted from incoming solar radiation.

Category:Meteorology

Complementary Metal-Oxide Semiconductor. A method of making silicon chips that results in low power consumption by the circuits.

Category:Meteorology

A contact anemometer connected to an electrical circuit which is so arranged that the average wind speed is indicated.

Category:Meteorology

An instrument used for measuring the specific gravity of a liquid.

Category:Meteorology

An instrument which measures the instantaneous rate at which rain is falling on a given surface. Also called a rate-of-rainfall gauge.

Category:Meteorology

The meteorological visual range, which can be estimated from the average extinction coefficient using the Koschmieder equation.

Category:Meteorology

The total area drained by a river and its tributaries. Same as river basin.

Category:Meteorology

Transmitted energy which is modulated in order to carry information. Usually, it is in the form of a radio- frequency sine wave, modulated either in amplitude or in frequency.

Category:Meteorology

A device which converts energy from one form into another, i.e. an ac generator transducer which converts the mechanical motion of anemometer cups into an electrical signal.

Category:Meteorology

An elongated area of relatively high pressure. Usually associated with and most clearly identified as an area of maximum anticyclonic curvature of the wind flow. The opposite of a trough.

Category:Meteorology

The audio-frequency signal transmitted by the Diamond-Hinman radiosonde when the baroswitch pen passes each fifteenth contact of the commutator, up to a number determined by the design of the commutator, and each fifth contact thereafter. This signal is t ...

A recording hair hygrometer.

Category:Meteorology

The volume of water required to cover one acre to a depth of one foot: 43,560 cubic feet.

Category:Meteorology

The wind speed and direction at various levels in the atmosphere above the level reached by surface weather observations.

Category:Meteorology

An instrument for measuring the difference of the solar radiation falling on both sides of a horizontal surface from the whole hemisphere.

Category:Meteorology

Readily taking up and retaining moisture.

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 ...
