• gradient wind — /wind/ a wind with a velocity and direction that are mathematically defined by the balanced relationship of the pressure gradient force to the centrifugal force and the Coriolis force: conceived as blowing parallel to isobars. Cf. geostrophic… …   Universalium

• gradient wind — Any horizontal wind velocity tangent to the contour line of a constant pressure surface or an isobar. This movement of air is to the result of a combination of three forces: pressure gradient force, geostrophic force, and cyclostrophic force. In… …   Aviation dictionary
