Sažetak

Unsatisfactory model forecasts of 2m temperature and cloudiness in inversion cases with fog and low stratus clouds have encouraged research of alternative parametrization for these processes that could be used in the operational version of the Aladin model. Few computationally cheap modifications are introduced and tested. Different cloud schemes and cloud overlap assumptions play more important role than the modifications in the radiation scheme.
