Results are presented from the merging of the lake model FLake into the community land-surface model JULES. It is shown, by comparison with observational data, that the combined JULES-FLake model performs more realistically than JULES with its original or upgraded parametrizations for inland water. Tests against observations from lakes in the UK and Sweden show that JULES-FLake gives results for both midlatitude and arctic lakes which are comparable to the original lake model, FLake. The accuracy of JULES-FLake as a general model of the land surface is therefore enhanced. Differences in sign of the model errors in the prediction of lake-ice thickness indicate possible future directions for development and testing of these models.
