## baroclinity

(

*Or*baroclinicity.) The state of stratification in a fluid in which surfaces of constant pressure (isobaric) intersect surfaces of constant density (isosteric).The number, per unit area, of isobaric–isosteric solenoids intersecting a given surface is a measure of the baroclinity. If the surface is horizontal, this number where α is the specific volume and

*N*is given by*p*the pressure. Barotropy is the state of zero baroclinity.*See also*barotropy.
