NOAA GREAT LAKES SEMINAR SERIES http://www.glerl.noaa.gov/news/seminars/ Date: Thursday, November 18, 2004 Time: 10:30 a.m. Title: "An Examination of Winds and Waves on Lake Superior Associated with the Wreck of the Edmund Fitzgerald on November 10, 1975" Speaker: Dr. David Schwab Physical Limnologist, GLERL Where: GLERL Main Conference Room 2205 Commonwealth Blvd. Ann Arbor, MI 48105 For directions: http://www.glerl.noaa.gov/facil/triptik.html Abstract The Regional Atmospheric Modeling System (RAMS) version 4.4 was used to simulate atmospheric conditions over Lake Superior during the storm associated with the sinking of the Edmund Fitzgerald in 1975. The run spanned 54 hours, from 00Z, 9 November 1975 – 06Z, 11 November 1975. The NCEP/NCAR Reanalysis was used for initial and boundary conditions for the run. The RAMS model had 6-hour temporal resolution, grid spacing of 2.5° x 2.5°, and 17 vertical levels. The sinking of the Fitzgerald occurred approximately 48 hours into the model run, at 0015Z, 11 November 1975. Since there were almost no wave observations in Lake Superior at this time, computer model simulations of the case have also been run using the GLERL/Donelan wave model to estimate the possible wave conditions experienced during the time of the Fitzgerald’s sinking. A computer animation of the results shows an area of waves with maximum significant waveheight greater than 7.5 m occurred in eastern Lake Superior at almost exactly the time the Fitzgerald was lost. From the meteorological simulation and the wave model run, it appears that the Fitzgerald could not have been in a worse place at a worse time.
