Thermal Wind Relationship in Isentropic Coordinates
- Isentropic surfaces have a steep slope in regions of strong
baroclinicity. Flat isentropes indicate barotropic conditions
and little/no change of the wind with height.
- Frontal zones are characterized by sloping isentropic surfaces which are vertically compacted (indicating strong static stability).
- In the stratosphere the static stability increases by about one order of magnitude.
