Abstract
We examine air parcel trajectories in the two-dimensional model for a cold front by Reeder and Smith. These are found to be in close agreement with trajectories deduced from analyses of summertime “cool changes” in southeastern Australia, adding further support to the applicability of the numerical model to this kind of cold front. The favorable comparison points also to the dynamical consistency of the conceptual model for the cool change, which has evolved from the analysis of data from observational experiments.
