Modelling precipitation in frontal rainbands

The main aim of this study is to establish the ability of a simple parametrization to represent adequately the microphysical processes acting in frontal rainbands. In order to do this we compare it with a more detailed parametrization in conditions typical of warm frontal and narrow cold frontal rainbands. Simulations using a 2-dimensional diagnostic model indicate that a mixed phase parametrization is required in dynamical models of high resolution.
