Physics of lakes 2

The 2nd volume of “Physics of Lakes” focuses on “Lakes as Oscillators,” exploring barotropic and baroclinic waves in both homogeneous and stratified lakes on a rotating Earth. Comprising 12 chapters, it begins with the classification of rotating shallow-water waves into gravity and Rossby waves. The discussion progresses to gravity waves in bounded domains of constant depth, including Kelvin, Poincaré, and Sverdrup waves, as well as their reflections in gulfs and rectangles and their behavior in sealed basins as barotropic ‘inertial waves proper.’ The text delves into gravity waves in circular and elliptical basins, leading to Kelvin-type and Poincaré-type waves and their balanced descriptions in various geometries. It also examines two-, three-, and n-layer fluids with sharp interfaces, detailing higher-order baroclinic gravity waves supported by experimental evidence from lakes like Lugano, Banyoles, and Biwa. The analysis of barotropic wave modes in Lake Onega highlights the need for careful interpretation of data and computational results. A summer field campaign in Lake Lugano emphasizes the importance of statistical analysis to align data with computational findings. Additionally, three chapters focus on topographic Rossby waves, identifying conditions under which baroclinicity has minimal impact and categorizing these waves into channel modes, Ball modes, and bay modes. The final chapter presents Chrystal-type equations
