In the absence of friction, the combined effect of the Coriolis force and pressure gradient force produce geostrophic winds at altitude above the ground. Geostrophic winds flow parallel to the isobars, with the pressure gradient force balancing the Coriolis force. These winds are typically found at high altitudes, such as in the jet stream.
