Abstract
SLAV is a mathematical model of the Earth’s atmosphere that predicts weather in future based on current weather conditions. This paper describes and evaluates the numerical algorithm based on the energy balance for implementing the LAKE model into SLAV. LAKE is an extended one-dimensional model of lake that has been tested in respect to thermal and ice regime at a number of lakes in contrasting climate conditions in a standalone mode. The results obtained from numerical simulations for lead times up to 4 month and retrospective forecasts of weather anomalies with the same lead time indicate the applicability of the developed approach to reproduce lake-atmosphere coupling.
