Defining the Wind Speed Index for the Temporal Plots

[Neil Davis]

The temporal plots on the GWA, have a variable called the Wind Speed Index, this value is the mean wind speed for that temporal period divided by the 10-year mean wind speed at that point. The temporal plots are not downscaled to the 250m resolution, but come from the mesoscale simulations with 3km resolution. Therefore, by presenting the temporal data as an index, you can adjust it for your region of interest, or even local points. Of course, this also means that features not resolved by the mesoscale model that affect the timing of the wind are not represented.
