Every 3 hours, the model developed atEawag calculates current speed and direction, as well as water temperature, using meteorological data (wind speed and direction at lake surface, air temperature, sunshine, etc.).
Surface currents are represented in the graph below by white moving lines, which show the recirculation of water.
The temperature at the surface of the lake is represented using a color palette: warm water is displayed in redand cold water in blue.
👉 The temperature is not uniform across the surface of the lake. Depending on where you are on the lake, the temperature can vary by several °C.
