Electronic Barometer: A barometer that uses a pressure transducer as a pressure sensor. The sensor has electrical properties (resistance or capacitance) that change when the atmospheric pressure changes.
Electronic Weather Monitoring
A weather station is a collection of equipment that measures local weather conditions.
An electronic instrument that broadcasts a microwave electromagnetic radiation signal and receives the reflected portion of this signal from a target.
An electron tube used as a low-power oscillator or a high-power amplifier at ultrahigh frequencies.

The electronic device which detects the backscattered radiation, amplifies it and converts it to a low-frequency signal which is related to the properties of the target.

DUATS - Electronic flight breifing and weather services for the aviation community. Fee-based system provided in conjunction with the FAA.
Radar - An electronic instrument, which determines the direction and distance of objects that, reflect radio energy back to the radar site. This is what meteorologists use to see rain or snow.
Computer Electronic machine capable of performing calculations and other manipulations of various types of data, under the control of a stored set of instructions. The machine itself is the hardware; the instructions are the program or software.
radar: an electronic instrument that broadcasts and receives microwave signals back from precipitation areas, and determines their location, height, movement, and intensity.
NAVAID:NEXRAD: Electronic Navigation Air Facility.
NEXRAD:NEXRAD: Next Generation Weather Radar.
NOAA: National Oceanic & Atmospheric Administration under the Dept. Of Commerce: Which includes the National Weather Service.
Klystron An electron tube used as a low-power oscillator or a high-power amplifier at ultrahigh frequencies. Noted for exceptional stability over long periods of transmission.
Klystron - the electronic component of the NEXRAD transmitter that generates the coherent radiation necessary for the determination of Doppler velocities. The WSR-88D typically transmits its radiation using a power of 750,000 watts.
An electronic instrument used to detect distant objects and measure their range by how they scatter or reflect radio energy. Precipitation and clouds are detected by measuring the strength of the electromagnetic signal reflected back.
A standard SNOTEL site consists of a snow pillow, a storage type precipitation gage, air temperature sensor and a small shelter for housing electronics.
DCP(Data Collection Platform) In hydrologic terms, an electronic device that connects to a river or rainfall gage that records data from the gage and at pre-determined times transmits that data through a satellite to a remote computer.
Inert gas Any one of six gases, helium, neon, argon, krypton, xenon, and radon, all of whose shells of planetary electrons contain stable numbers of electrons such that the atoms are chemically inactive.
Conventional thermometers, hygrometers, barometers and rain-gauges are of course available, but rugged, easy-to-use distant-reading electronic units to monitor temperature, relative humidity and rainfall are also offered.
radar"(Coined word for radio detection and ranging.) An electronic instrument used for the detection and ranging of distant objects of such composition that they scatter or reflect radio energy.
photoelectric Of or relating to the electrical effects of light, including the emission of electrons, the generation of a voltage, or a change in resistance.
In chemistry, atoms or specific groupings of atoms that have gained or lost one or more electrons, as the "chloride ion" or "ammonium ion.
Retreater With the conversion to electronic maximum/minimum thermometers by most governmental weather services, this term is hardly used anymore.
LIGHTNING A sudden and visible discharge of electricity produced in a thunderstorm, creating a flash of light generated by the flow of electrons between opposite charged parts of a cumulonimbus cloud.
K AMSCold Air MassK CoronaIn solar-terrestrial terms, of the white-light corona (that is, the corona seen by the eye at a total solar eclipse), that portion which is caused by sunlight scattered by electrons in the hot outer atmosphere of the ...
TRANSMISSOMETER An electronic instrument system which provides a continuous record of the atmospheric transmission between two fixed points.
An electronic instrument system which provides a continuous record of the atmospheric transmission between two fixed points. By showing the transmissivity of light through the atmosphere, the horizontal visibility may be determined.
Radio Detection And Ranging. An electronic instrument used to detect precipitation by the ability of rain droplets (and other hydrometeors) to reflect microwaves (radio waves) back to a receiver.
Radial velocity ...
RS 232: A specification of the Electronic Industries Association defining a standard serial data interface. A standard interface between a computer input/output port and a peripheral device.
Lightning - A sudden flash of light generated by the flow of electrons between oppositely charged parts of a cumulonimbus cloud or between the cloud and the ground.

An electrified region of the upper atmosphere where fairly large concentrations of ions and free electrons exist.
Isobar(6)
A line connecting points of equal pressure.
Solar wind A stream of charged subatomic particles (mainly protons and electrons) flowing into space from the sun.
Ionosphere An electrified region of the upper atmosphere where fairly large concentrations of ions and free electrons exist.

The F region is subdivided into the F1 and F2 regions. The F2 region is the most dense and peaks at altitudes between 200 and 600 km. The F1 region is a smaller peak in electron density, which forms at lower altitudes in the daytime.
The F1 region is a smaller peak in electron density, which forms at lower altitudes in the daytime.
A difference of pressure is the only agency that can cause a wind; the Coriolis force acts perpendicular to the velocity (like the magnetic force on a moving electron) and cannot affect the velocity.
