Abstract
The application of the lake model FLake to represent the effect of lakes in numerical weather prediction (NWP) and climate models is discussed.As a lake parameterisation scheme FLake is implemented into the limited-area NWP model COSMO.Results from a numerical experiment with the coupled COSMO-FLake system, including the complete COSMO-model data assimilation cycle, indicate a good performance with respect to the lake surface temperature and to the freeze-up of lakes and the ice break-up.The use of FLake removes a significant overestimation of the lake surface temperature during winter that is typical of the routine COSMO sea surface temperature analysis.Some challenging issues are discussed, such as the development of external-parameter fields and the lake temperature spin-up following a cold start of FLake in an NWP or climate model.
