Application of a simple model for ice growth to the Lake St. Moritz, Switzerland
Abstract We present a Simple Lake Ice Model to calculate the growth rate of lake ice in a cold and relatively dry climate. The focus is on Lake St. Moritz, Switzerland, which has an area of 0.78 km 2 and is about 45 m deep. In winter the lake is extensively used for recreational purposes, including...
