Isentropic vertical coordinate

From Glossary of Meteorology



isentropic vertical coordinate

Vertical coordinate for atmospheric models defined as the potential temperature of the model atmosphere.

In practice the isentropic vertical coordinate is replaced by or changed gradually to a terrain- following coordinate near the ground; a change to pressure coordinates near the top of the model atmosphere has also been used.
See hybrid vertical coordinate, vertical coordinate system, pressure vertical coordinates.
