Numerical modeling of wintertime dynamics in a small lake


The goals of the pre-comprehensive seminar are threefold. First I will provide motivation and some background on why studying physical processes under ice cover is important to understanding the health of a lake ecosystem followed by a background discussion on the hydrodynamic and ice models I am using. I will include the appropriate scaling of the equations of motion to highlight the dominant balance in an example case. Second, I will provide the most up to date state of my research and describe some of the parameterizations being used in the model and effects that these parameterizations have on the large scale characteristics of the flow. Lastly, I will provide several directions for future study, the first being the high-resolution modeling of small scale dynamics in the presence of ice and snow, and the second being regional modelling of the eastern basin of Lake Erie and how the Grand River Plume (GRP) affects the dynamics in the basin when ice is present.
