Sinking simulation

On November 10, 1975, Lake Superior swallowed the Edmund Fitzgerald, along with her 29 crew and cargo of almost 26,000 tons of ore. Thirty years later, researchers at the

have built a simulation of the storm using the latest forecast technology.

November storms tend to roll across the Great Lakes, gathering strength and fury. The one that sank the Fitzgerald was no exception. Simulations of weather events like this allow scientists to identify and study characteristics of severe storms. Looking back also helps forecasters and weather modellers improve severe weather prediction techniques.

Robert Aune, a scientist with the US National Oceanic and Atmospheric Administration (NOAA) stationed at the UW-Madison Space Science and Engineering Center (SSEC), recently created a simulation of the storm that swept across Lake Superior on that November evening.

Satellite technology was brand new in 1975, so Aune obtained conventional observations through an ongoing project at the National Center for Environmental Prediction and the National Center for Atmospheric Research that uses modern techniques and technology to reanalyse weather data from 1949 through the present.
