See hurricane beacon.

Category:Meteorology

Very small precipitation drops (diameters less than 0.5 mm) that appear to float with air currents while falling in an irregular path. Unlike fog droplets, drizzle falls to the ground.

Category:Meteorology

An instrument resulting from the combination of a thermograph and a hygrograph and furnishing, on the same chart, simultaneous time recording of ambient temperature and humidity.

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

The change in the measured transducer output caused by changes in ambient temperature. Usually expressed a percentage of full scale.

Category:Meteorology

The ratios, to the mean wind speed, of the average magnitudes of the component fluctuations of the wind along three mutually perpendicular axes.

Category:Meteorology

Navy Operational Global Atmospheric Prediction System. A global meteorological model operated by the Department of Defense.

Category:Meteorology

An air-launched balloon designed to be released in the eye of a tropical cyclone, float within the eye at predetermined levels, and transmit radio signals for RDF positioning.

Category:Meteorology

Occupational Safety and Health Administration. A regulatory office of the U.S. Department of Labor.

Category:Meteorology

The older name for the Celsius temperature scale. Officially abandoned by international agreement in 1948, but still in common use.

Category:Meteorology

A general term for instruments which sample atmospheric suspensoids by impaction. Same as impactometer.

Category:Meteorology

A unit of energy equal to 1.356joules.

Category:Meteorology

An instrument designed to record the duration of sunshine at a given location without regard to intensity. See Campbell- Stokes recorder, Jordan sunshine recorder, Marvin sunshine recorder, Pers sunshine recorder.

Category:Meteorology

A balloon designed to float at a constant pressure level. This may be accomplished by a pressure valve which controls the release of ballast so as to maintain flight above a selected pressure level until the supply of ballast is exhausted. See Moby Dick b ...

Category:Meteorology

The sum of solar and terrestrial radiation.

Category:Meteorology

A system of estimating and reporting wind speed, originally based on the effect of various wind speeds on the amount of canvas that a full-rigged nineteenth century frigate could carry.

Category:Meteorology

A diagram showing the intensity of the radiation field in all directions from a transmitting radio or radar antenna at a given distance from the antenna.

Category:Meteorology

A vent used with pressure sensors to reduce the effect of wind on the pressure inlet. It is normally mounted remotely and connected to the sensor using airtight tubing.

Category:Meteorology

See ceilometer.

Category:Meteorology

The process by which one object becomes adhered to another by the binding action of ice.
