- Wind Weighting
- Wind Station

After adding the wind station parameters to the 2DH View, the wind station marker will be added to the model domain, and on the legend as well (Figure 2). To show the options available for display, activate the selection and edit mode of the Wind Station in the Layer Control, then RMC on the wind station marker. Options include View Data Series, Edit Data Series, Show Wind Roses as shown in Figure 2.
Select Show Wind Roses option, a Select Times to Plot form will pop up. The default start time and end time in this form are from input data of the wind station (wser.inp), but we can enter a new start time and end time in this form and then click OK button (Figure 3). A wind rose plot will then be displayed as shown in Figure 4.
