Drag the wind direction field into the ‘ROWS’ area of the Pivot Table Fields toolbar.
Drag the Mean Wind Speed field into the ‘COLUMNS’ area of the ‘PivotTable Fields’ toolbar. Arrange the wind speed data into a summary table using the PivotTable Toolbar Select your wind speed table (the 2 columns containing wind speed and direction values) and click the ‘Insert’ tab and then select ‘PivotTable’. The calm data is excluded from the wind rose diagram and is explained further in Section 10. In order to do this you should ensure that any mean wind speeds which have values of 0 have been assigned the wind direction “Calm” (or something equivalent). Ensure that ‘0 m/s’ wind speed values have been taken into account It is then important that the wind direction is converted from degrees to Cardinal Wind Directions i.e. The data may look like the following: Note: the 2 columns in bold are the only columns needed to construct a wind rose diagram. For example, you may have access to hourly mean wind speeds and direction taken for the last 2 years. The data will need to comprise of mean (normally hourly) wind speeds values and the associated wind direction values. You will need to source the appropriate wind speed data which related to a specific location and, ideally, height. However, in the name of providing a good service for our website viewers, we have include the procedure below. STEREONET ROSE DIAGRAM PROFESSIONAL
The process is fairly long and tricky, and the end result is not the professional Wind Rose that you would produce when using the WRE Web App or WRE v1.7. You will end up with a plot looking like the example given below: Wind rose diagram created using only excel It is possible to make a wind rose (of sorts) by using excel only.
