Researchers have greater access of data to recreate historical events. The University of Wisconsin-Madison simulated a powerful storm that occurred on Nov. 10, 1975, sinking the cargo ship Edmund Fitzgerald, the subject of a song by Gordon Lightfoot that claimed 29 crew members. As noted in a previous column, the Bulletin of the American Meteorological Society analyzed past weather data and recreated the storm at the exact time of the Edmund Fitzgerald’s demise. This data was input into a model that recreates weather forecasts and conditions from targeted time periods. The results of these simulations offer another snapshot of what occurred during the disaster from the time it left port until it sank in Lake Superior. These examples further the study of severe storms at a designated time. Fastcast: Stormy.
