Simulation of the Seasonal Variability of Hydrothermodynamical Fields in Lake Kinneret

Simulation of the Seasonal Variability of Hydrothermodynamical Fields in Lake Kinneret We discuss the results of a numerical experiment devoted to the investigation of the variability of the three-dimensional fields of temperature and current velocity brought about by the seasonal variability of external factors: solar radiation, atmospheric fields, discharge of the river Jordan, and water intake for economic necessities. We use a multilayer model in isopycnic coordinates with an upper mixed layer. We set atmospheric factors in the form of monthly average fields that are uniform over space and linearly interpolated in time. We compare the computed fields of heat flux and evaporation through the lake surface, level, temperature, and currents with data of observations. We note a qualitative agreement of temperature fields during the whole year and current velocities in winter when the lake is, in fact, barotropic. In summer when the lake is stratified, currents in the model turn out to be weaker than in observations. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Oceanography Springer Journals

Abstract

We discuss the results of a numerical experiment devoted to the investigation of the variability of the three-dimensional fields of temperature and current velocity brought about by the seasonal variability of external factors: solar radiation, atmospheric fields, discharge of the river Jordan, and water intake for economic necessities. We use a multilayer model in isopycnic coordinates with an upper mixed layer. We set atmospheric factors in the form of monthly average fields that are uniform over space and linearly interpolated in time. We compare the computed fields of heat flux and evaporation through the lake surface, level, temperature, and currents with data of observations. We note a qualitative agreement of temperature fields during the whole year and current velocities in winter when the lake is, in fact, barotropic. In summer when the lake is stratified, currents in the model turn out to be weaker than in observations.
