An offshore tower is used for measuring a wind velocity over a sea, but the tower affects the wind velocity and wind direction at the location of a sonic anemometer. It is, therefore, important to determinate an installation position of a sonic anemometer that is less affected by the tower. In the present study, large-eddy simulation is implemented to investigate the effect of the tower on the wind velocity at the location of the sonic anemometer. The wind velocity at the location of the sonic anemometer is slightly larger than the inflow velocity at any wind direction. In addition, the wind velocity of the sonic anemometer located at both the windward and downward direction is strongly affected by the tower.
