Summary: | Two series of aerial and surface observations of lakes in Canada arc presented in which wave formation dcpendcd on the stability of the air over the water. In the first set of observations a cold, deep lako remained mirror-smooth under wind conditions that devel-oped gravity waves 44 in. high on nearby warmer, shallow lakes. The second observation is of Dubawnt Lake, a large, cold, arctic lake, where wind waves developed only in the lee of the upwind shore and of islands and disappeared a mile or less downwind. Great stability of the air over the lakes leading to reduced surface stress results from warm air flowing over very cold water. INl’RODUCTION The minimum wind velocity necessary to generate surface waves on water has been the subject of considerable theoretical in- |
