Some additional light shed on surges

Abstract

The occurrence of an internal undular surge at a point 2.5 km north of the south end of Seneca Lake, New York, is revealed by a series of 96 bathythermograph casts, made at 1-hour intervals. This suggests that the area of generation of the surge is in the extreme south end of the lake. Wind data collected concurrent with the temperature observations and the bathymetry of the lake negate the hypotheses that the surge is wind induced or morphologically induced. Some nonlinear interaction seems to be responsible for surge generation.
