| Title: | Potential vorticity conservation, hydrostatic adjustment, and the anelastic approximation |
| Publication: | J. Atmos. Sci., 52, 2302-2312 |
| Abstract: | An examination of the anelastic equations of Lipps and Hemler shows that the approximation requires that the temperature and potential temperature scale heights of the base state are large compared to the pressure and desnsity scale heights. |

| Title: | Generation of moist potential vorticity in extratropical cyclones |
| Publication: | J. Atmos. Sci., 52, 3263-3281 |
| Abstract: | The mechanism of moist potential vorticity (MPV) generation in a three-dimensional moist adibatic and frictionless flow is investigated. It is found that MPV generation is governed by baroclinic vectors and moisture gradients. Negative (positive) MPV can be generated in regions where baroclinic vectors have a component along (against) the direction of the moisture gradients. |
