1. In the free atmosphere, geostrophic wind relationships should be used. 2. In other words, no vertical wind shear of the geostrophic wind . 3. Unlike geostrophic currents, and geostrophic winds are examples of inertial waves. 4. They follow the principle of geostrophic winds . 5. Isallobaric gradients are important components of the wind as they increase or decrease the geostrophic wind . 6. The geostrophic wind component is the result of the balance between Coriolis force and pressure gradient force. 7. Look at geostrophic wind article in wikipedia and you will be able to solve this problem without difficulty. 8. The gradient wind is similar to the geostrophic wind but also includes centrifugal force ( or centripetal acceleration ). 9. To maintain balance, the geostrophic wind aloft and below adjust, such that regions of divergence / convergence form. 10. Such isobaric surfaces will also be isothermal surfaces, hence ( from the thermal wind equation ) the geostrophic wind will not vary with depth.
