Pressure gradient — In atmospheric sciences (meteorology, climatology and related fields), the pressure gradient (typically of air, more generally of any fluid) is a physical quantity that describes in which direction and at what rate the pressure changes the most… … Wikipedia
Pressure-gradient force — The pressure gradient force is not actually a force but the acceleration of air due to pressure difference (a force per unit mass). It is usually responsible for accelerating a parcel of air from a high atmospheric pressure region to a low… … Wikipedia
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
