Baroclinity is proportional to which again is proportional to the angle between surfaces of constant pressure and surfaces of constant density. Thus in a barotropic fluid (which is defined by zero baroclinity), these surfaces are parallel. Areas of high atmospheric baroclinity are characterized by the frequent formation of cyclones.
