geostrophic flow

Geostrophic flow is a type of ocean or atmospheric movement where the force of Earth's rotation balances the pressure differences in the water or air. When there is a change in pressure, fluid naturally wants to move from high to low pressure, but due to the Coriolis effect from Earth's rotation, this movement is deflected. As a result, the flow runs parallel to the pressure gradient rather than directly across it. This balance creates stable, large-scale currents such as ocean gyres and wind patterns, which are essential for climate and weather distribution.
