Effect of the Coriolis force on convection in a deep lake: Numerical experiment

Convection in a deep lake at temperatures close to the temperature of maximum density (TMD) is studied on the basis of a quasi-two-dimensional nonhydrostatic model of hydrothermodynamics with allowance for the compressibility of water. The rotation of the Earth is accounted for in the model by two components of the Coriolis force. Convection in deep lakes is influenced by the fact that the TMD is found to be dependent on pressure and salinity. Results are compared from three numerical experiments: without allowance for the Coriolis force, and with one and two Coriolis parameters. The results demonstrate the substantial effect of the Coriolis force, which shows the need to account for it in modeling convective processes in natural objects.
