"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. " - Geostrophische vorticity
