Integrated Flood Observing and Warning System. National Weather Service flood warning program.

A device that allows a terminal or computer at one location to communicate with a terminal or computer at a distant location via wire or phone lines.

An instrument for measuring the pressure of gases and vapors. A mercury barometer is a type of manometer.

A momentary decrease in the speed of the wind.

A component of the wind (often using Cartesian coordinates. i.e. X and Y wind vectors). Also, an arrow representing wind velocity, drawn to point in the direction of the wind and with a length proportional to wind speed.

The humidity transducinu element in a Diamond-Hinman radiosonde. Also called electrolytic strip.

A rain gauge capable of measuring very small amounts of precipitation. Also called micropluviometer, trace recorder.

A form of psychrometer with wet-bulb and dry-bulb thermometers mounted on opposite sides of a specialty designed graph of the psychrometric tables. It is so arranged that the intersections of two curves determined by the wet-bulb and dry-bulb readings -yi ...

That part of snow melt that reaches stream channels as runoff.

One of several constant-pressure levels in the atmosphere for which a complete evaluation of data derived from upper air observations is required.

An instrument, dropped from high attitude and carried by a stable parachute. used to measure the vertical component of turbulence aloft.

The total of all deviations of a transducer's output from a specified straight line in a constant environment.

A generic term for any machine that enables a human being to communicate with a computer.

The difference between the solar radiation directed downward and upward; net flux of solar radiation.

Overflowing by water of the normal confines of a stream or other body of water, or accumulation of water by drainage over areas which are not normally submerged.

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 rain-intensity gauge.

A small anemometer with flat vanes which indicates the number of linear feet or meters of air which have passed the instrument during its exposure.

An old nautical term for mercury barometer.

Wind with a speed between 4 and 6 knots (4 and 7 mph), Beaufort scale number 2.
