DYNAMICAL MODEL OF GUST FRONT

The dynamics of gust fronts generated by Great Plains thunderstorms were considered from the viewpoint of aviation safety. The past and current understanding of the structure and mechanics of gust fronts has been thoroughly reviewed and the major problems which are currently obstructing progress have been outlined. Numerical simulation is an especially useful tool in the study of gust fronts because observational capability is so poor. So far, no simulation experiment has been successful in depicting a realistic gust front extending a long distance ahead of the parent thunderstorm. A successful numerical simulation is urgently needed for comparison with data from the new multi-Doppler radar system, and to enhance the credibility of the conceptual model of the gust front, which has evolved by induction from the available observations and physical reasoning. After a technical discussion of several simulation attempts, it is concluded that a well-designed three-dimensional simulation is required.
