ALL meanings of geostrophic wind
ge·o·stroph·ic wind
G g - noun geostrophic wind a wind whose velocity and direction are mathematically defined by the balanced relationship of the pressure gradient force and the Coriolis force: conceived as blowing parallel to isobars. 1
- noun geostrophic wind (meteorology) A wind whose direction and speed are determined by a balance of the horizontal pressure gradient force and the force due to the earth's rotation to the left in the northern hemisphere and to the right in the southern hemisphere. 0
- noun geostrophic wind (meteorology) That horizontal wind velocity for which the Coriolis force exactly balances the horizontal pressure gradient force. The geostrophic wind is thus directed along the contour lines on a constant-pressure surface (or along the isobars in a geopotential surface) with low elevations (or low pressure) to the left in the northern hemisphere and to the right in the southern hemisphere. 0
