Abstract
The numerical frontogenesis model of Williams (1973) is modified to
include moisture with its subsequent condensation and release of latent
heating. The turbulent diffusions of momentum, heat and moisture are
represented with various coefficients. The numerical solutions show
realistic quasi-steady fronts forming within one to two days. These
solutions are examined and compared over a range of the various coefficients,
and various ranges of temperature.
Inclusion of moisture in the model causes intensification of baroclinicity
at mid and upper levels. Also noted is a sensitivity of the
moist model to reference potential temperature due to the exponential
relationship between saturation vapor pressure and temperature.
