From Glossary of Meteorology


An upper-air sounding that includes determination of wind speeds and wind directions.

Historically, wind data were obtained by tracking a balloon-borne radiosonde with a radio direction finder. Contemporary methods include measuring position or radiosonde velocity from a global positioning system or Loran radio navigation signals.
