Short summary
The regional climate of western Europe was simulated using an atmospheric and land surface model. This study aims at improving the coupling of the models, by applying an alternative method for the update frequency of the atmospheric and soil parameters. The results show that a daily update of the atmosphere and soil outperforms a continuous approach. However, keeping the land surface continuous but having daily atmospheric updates is preferable at times, as it benefits from soil moisture memory.
