A series of 33 charts is presented to illustrate the ice cover on the Great Lakes for three classifications of winter: mild, normal, and severe. The freezing degree-day concept was employed to make these classifications. One meteorological station on each lake was selected that would reflect a lakewide freezing degree-day accumulation, based on daily average temperatures for ten years from 32 meteorological stations. Twenty years of temperature records from the selected representative stations were examined to determine a classification for the winter season. Six ice charts are presented for each of the Great Lakes. Four charts illustrate the characteristic patterns and extent of ice cover during a normal winter, with the first chart portraying the ice cover during an early development stage, the second during an advanced stage at mid-season, the third depicting the ice distribution during the period of maximum ice cover, and the fourth chart indicating the ice cover patterns during the early decay period. Two charts show the maximum extent of ice cover during the mild and severe winters. The ice cover on Lake St. Clair is portrayed by three charts during a normal winter; the early development stage, maximum ice cover, and the decay period. (Author).
