Abstract : Case studies were undertaken on mesoscale convective systems (MCS) an individual storm basis to examine factors influencing MCS propagation characteristics. This was done by examining numerous specific storms during a portion of the warm seasons (June-September) of 1990 through 1992. Three cases were presented in detail to illustrate the types of propagation typically exhibited by mesoscale convective systems. This research attempts to analyze why MCSs exhibit a particular type of propagation and if that propagation can be accurately predicted by forecasters on an operation basis. Parameters such as moisture convergence, surface boundaries (fronts, dry lines, etc), Convective Available Potential Energy (CAPE), equivalent potential temperature, vertical wind shear, and others were used in the diagnosis of a particular region where a storm grew and propagated toward.
