Hawaii - Wind Speed 100 metres - Hawaii Statewide GIS Program

The accompanying maps, which incorporate the adjustments described in the previous section, show the predicted mean annual wind speed in Hawaii at heights of 30, 50, 70, and 100 m. A map of mean annual wind power density at 50 m is also provided; this can be compared directly with the previous wind resource map of the state from the national wind resource atlas.

The mean speed and power describe different aspects of the wind resource, and both can be useful in different ways. The mean speed is the easiest for most people to relate to and is consequently the most widely used. However, it does not directly measure the power generation potential in the wind. Some experts regard the mean wind power, which depends on the air density and the cube of the wind speed, as a more accurate indicator of the wind resource when assessing wind project sites.
