## 5 Conclusions  
LES using a FBL technique approach were performed for neutral atmospheric conditions with the Coriolis force included. The mean wind shear including the mean wind veer due to the Coriolis force can be included in the FBL. The variation of the Coriolis force due to the reduced velocity in the wake, the so-called Coriolis correction, was added with an extra force term. The study also examined the impact of the wind veer and the change in Coriolis force in the wake region on the development of the wake. Including the wind veer in the simulation for a row of 4 turbines turns the wake behind it to the right and including the Coriolis correction turns it to the left. The implemented method shows the expected results considering the used wind veer and the equations for the Coriolis correction. When including both the veer and the Coriolis correction the resulting turn is to the right, indicating the dominant impact of the wind veer for the studied conditions. These results using LES are in line with the earlier findings from the study of [PERSON] (2015) using RANS. To study the impact of the Coriolis force on the total energy production in a wind farm cluster an idealized farm to farm interaction case was used. For a full wake direction in the idealized farm to farm interaction case it can be seen that when wind veer and the Coriolis correction are included relative production for a full wake direction increases by around 3%. This is only slightly less than when just wind veer is included. It can be noted that a lack of a yaw controller in the simulations could

This is because the change of wind direction due to the Coriolis force could provide a smaller yaw misalignment than when no yaw controller is used. To conclude, the FBL technique has been used including a wind veer and also a Coriolis correction. The results show that the Coriolis force impact on the mean wind shear (the wind veer) is greater when compared to its local impact due to the reduction of wind speed in the wake (here included as a so-called Coriolis correction). To include all aspects of the Coriolis force the implemented Coriolis correction can be used. The results indicate however that FBL technique can be used for studies of long distance wakes without including a Coriolis correction but efforts needs to be taken to use a wind shear with a correct mean wind veer. This is of importance to asses the results from earlier studies using the FBL-technique without including the effects of the Coriolis force or only including the wind veer. In this study neutral atmospheric conditions were considered. The atmospheric conditions are expected to impact both the wind shear including the wind veer and the turbulence level which impact the recovery of the velocity in the wake. It could therefore be of interest for future work to investigate the relative impact of the different contributions of the Coriolis force in unstable and stable atmospheric conditions as well.
