A Review of Vorticity Waves in Lakes
Long-period wave motion in lakes may be of two types, either internal gravity waves or vorticity waves. Internal gravity waves have long been identified as an important component of long-period motion in large stratified lakes. Less attention has been given to the identification of vorticity waves which may theoretically exist in unstratified as well as stratified lakes. So far vorticity waves have only been convincingly identified only in Lake Michigan. Here we examine some elementary models of vorticity waves in channels and rectangular basins. The characteristics of vorticity waves in these idealized models are discussed to provide guidance for a search in Lake Champlain for these waves.
