Abstract
The lake model FLake was incorporated into the European Centre for Medium-Range Weather Forecasts (ECMWF) land-surface scheme HTESSEL. Results from global offline simulations are
presented in order to evaluate the model performance in different climates and assess the impact of lake representation on the surface energy balance. The model was forced by ECMWF reanalysis
ERA-Interim (1989–2005) near surface meteorology and surface radiation fluxes for the entire globe. Model validation includes lake surface temperatures and lake ice duration. The impact of
the snow insulation on lake ice cover duration is discussed, as well as the sensitivity of results to the lake depth. Results show changes in the variation of surface energy storage, and
changes in the partition of surface energy fluxes in high latitude and equatorial regions, respectively. General aspects concerning the incorporation of lake models into General Circulation
Models for weather forecast and climate modelling are discussed. Mehr anzeigen
