WebQuasi-geostrophic theory is a mathematical theory used to describe the motion of fluids in the atmosphere. The theory is based on the assumption that the atmosphere is a rotating, stratified fluid that experiences a balance between the Coriolis force and the pressure gradient force. This balance is known as geostrophic balance. WebGeostrophic definition, of or relating to the balance between the Coriolis force and the horizontal pressure force in the atmosphere. See more.
