Tor Bergeron
Bergeron was a Swedish meteorologist. The name for the process also sometimes recognises the scientists Alfred Wegener and Walter Findeisen. According to Wikipedia: "Bergeron was one of the principal scientists in the Bergen School of Meteorology, which transformed this science by introducing a new conceptual foundation for understanding and predicting weather. While developing innovative methods of forecasting, the Bergen scientists established the notion of weather fronts and elaborated a new model of extratropical cyclones that accounted for their birth, growth, and decay. Bergeron is credited with discovering the occlusion process, which marks the final stage in the life cycle of an extratropical cyclone."
