Numerical Simulations of the Rapid Cyclogenesis Over Canada and Evolution of a Cold Front Observed on 25-26 April 1979 (sesame-Ave-Iii)

The rapid development of a cyclone over Canada and a cold front over the United States were the major weather systems observed on 25-26 April 1979 during the period of SESAME-AVE (Severe Environment Storm and Mesoscale Experiment-Atmospheric Variability Experiment) III. The objectives of this study are two-fold; one is to investigate the mechanisms of this rapid cyclogenesis, the other is to discuss the synoptic- and meso-scale environment with the cold front. A regional scale prediction model, which is the quasi-Lagrangian nested model developed by Mathur (1983) and modified in this study, was used to achieve these objectives. FGGE (First GARP (Global Atmosphere Research Program) Global Experiment) level IIIb and IIb data were used as input and verification data for numerical simulations, and for a diagnostic study.
