Rawinsonde

Rawinsonde Radiosonde which is tracked by radar or radio-theodolite to measure the wind aloft.

Rawinsonde weather balloon just after launch. Notice a parachute in the center of the string and a small instrument box at the end. After release it measures many parameters.

rawinsonde"An upper-air sounding that includes determination of wind speeds and directions. Historically, wind data were obtained by tracking a balloon-borne radiosonde with a radio direction finder.

rawinsonde - An upper-air weather observation system (from the surface to approximately 30 km altitude) made by balloon-borne instrument package (radiosonde) that provides direct measurement of ambient air temperature, pressure, ...

RAWINSONDE An upper air observation that evaluates the winds, temperature, relative humidity, and pressure aloft by means of a balloon-attached radiosonde that is tracked by a radar or radio direction-finder.

RAWINSONDE: A method of upper air observation consisting of an evaluation of the wind speed and direction, temperature, pressure,and humidity aloft by means of a balloon-borne radiosonde tracked by radar or a radio theodolite.

rawinsonde observation—A combined winds aloft and radiosonde observation. Winds are determined by tracking the radiosonde by radio direction finder or radar.

Rawinsonde: a radiosonde that is tracked to measure winds. Red Flag Warning: a term used by fire weather forecasters to alert land managers to an imminent or ongoing weather event that could cause dangerous fire activity.

Rawinsonde(6) An instrument carried by weather balloons to measure the temperature, humidity, pressure, and winds of the atmosphere. Reflection(6) ...

Rawinsonde- A balloon that is tracked by radar to measure wind speeds and wind directions in the atmosphere.

Radiosonde (Rawinsonde): An instrument package carried upward by weather balloons to measure the vertical profile of atmospheric temperature, relative humidity and pressure from the surface into the stratosphere.

It is a type of rawinsonde system. Rain Precipitation composed of liquid water drops more than 0.5 mm in diameter, falling in relatively straight, but not necessarily vertical, paths. Compare to drizzle.

A type of rawinsonde. RADIAL VELOCITY A type of velocity that expresses motion toward or away from a given location. In Doppler radar, it is the component of motion that is parallel to the radar beam.

RAWIN: A rawinsonde observation. RAWINSONDE: Tracking a radiosonde aloft to determine the wind speed and directions up to 100,000+ feet. Red Sprites: Large dim flashes of light which appear above thunderstorms.

VERTICAL TEMPERATURE PROFILE A series of temperature measurements taken at various levels in the atmosphere that show the thermal structure of the atmosphere over a specific location. Obtained through a rawinsonde sounding or comparable method, ...

rawinsonde A radiosonde that is tracked to measure winds. reflection The process whereby a surface turns back a portion of the radiation that strikes it.

pressure and humidity by means of a small, expendable radio transmitter. Radiosondes can be tracked by radar, radio direction finding, or navigation systems (such as the satellite Global Positioning System) to obtain wind data. See also rawinsonde.

" Another type is a "rawinsonde," which is a radiosonde that is tracked by either radar or or a radio direction finder such that wind direction and speed aloft can be plotted for various vertical layers.
