Cyclostrophic wind
The model of the cyclostrophic winds ( Greek kyklos 'circle', verse 'rotation') describes the formation of wind in small-scale structures, with circular isobars , e.g. B. the emergence of tornado and dust devils .
Due to the circular motion, the centrifugal force occurs in addition to the pressure gradient force . The pressure gradient force directed towards the center of the printed structure and the outward centrifugal force are in equilibrium. The resulting circular wind is known as the cyclostrophic wind.
The Coriolis force can no longer be neglected for larger printed matter . One then speaks of the geostrophic-cyclostrophic wind (or the equivalent of the gradient wind ).
