Thegeostrophic wind is standing at 500 m with a free stream velocity equal to 10 m/s.The description of the model is completed with the following figure 3.2, showing thedifference in the profile of the hill obtained with a section of the Y-Z plane, betweena “cos 2 ” and a “flatted” hill.Figure 3.2: View of the geometrical models “cos 2 ” and “flatted” hill from the inlet sections.The “cos 2 ” hill has been built through the automatic procedure of the WindSimsoftware, which draws the hill shape using the following equation.28
