isentropic thickness chart isentropic thickness chart[¦īs·ən′träp·ik ′thik·nəs ‚chärt] (meteorology) A thickness chart of an atmospheric layer bounded by two selected isentropic surfaces (surfaces of constant potential temperature); the thickness of such a layer is directly proportional to the static instability of that layer; hence, these charts have been called instability charts. Also known as thick-thin chart. |
