The color overlay on the map allows you to compare different regions using the color scale located on the left side of the Annual Mean Wind Speed tool. "Warm" colors like brown and orange indicate higher wind speeds. "Cool" colors like purple and blue indicate lower wind speeds. You can select different overlays based on the particular hub height you are interested in: 20 meters, 50 meters, and 80 meters.

In some high latitude areas in the Northern Hemisphere, and near coastal regions, you may notice some sharp color changes. If you zoom in on these locations, you will notice these sharp color changes eventually disappear. For visualization purposes, we show a different color overlay and dataset over water and at high latitudes where the Wind Prospecting Tools do not display data.
