Same as windsock.

Amount of solar radiation incident, per unit area and time, on a surface which is perpendicular to the radiation and is situated at the outer limit of the atmosphere, the earth being at its mean distance from the sun. It equals approximately 2.00 ly/ min ...

Generally, the relative states of inflow, outflow, and storage of moisture over a given area of earth's surface.

An instrument used to measure the amount of dew formed on a given surface.

A cover which fits over a large inflated balloon to facilitate handling in high or gusty winds.

Temperarure at which a liquid solidifies under any given set of conditions. It may or may not be the same as the melting point or the more rigidly defined true freezing point or (for water) ice point.

A form of data transmission in which the bits of each character are sent one at a time along a single communication path. Compare to parallel data transmission.

(1) The ratio of the speeds of a chemical reaction at two temperatures differing by 10

An instrument used to determine atmospheric pressure or elevation by observing the boiling point of water or both liquids. The sensitivity of the hypsometer increases with decreasing pressure, making it more useful for high altitude work.

Precipitation composed of balls or irregular lumps of ice with diameters between 5 and 50 mm.

A measure of the attenuation due to scattering, of light as it traverses a medium containing scattering particles.

Contraction for pilot balloon observation.

Line drawn through geographical points recording equal amounts of precipitation during a given time period or for a particular storm.

Central Processing Unit. The part of a computer which controls and directs all functions.

For a given locality and month, an empirical expression devised for the purpose of classifying climates numerically on the basis of precipitation and evaporation.

In meteorology, a deflecting force acting on a body in motion and resulting from the earth's rotation. It deflects air currents to the right in the northern hemisphere and to the left in the southern hemisphere, thus having an effect on wind direction.

Same as aneroid barometer. Holostelic means wholly made of solids, while aneroid means devoid of liquid.

An early and once universal name for the mercury barometer.

A general name for instruments which detect the presence of (but do not necessarily measure) small electrical charges by electrostatic means. Compare to electrometer.

A wind vane used to obtain the horizontal and vertical components of the wind.
