Warning - This page is not for the faint hearted
Wind databases and atlases such as the NOABL uk wind map often only give an estimated average wind speed for a location. As we all know, the wind does not constantly blow at a set speed day-in day-out throughout the year. In fact the wind normally blows at a speed below the average wind speed with the average being lifted by a few periods of high wind speeds. As the energy available is related to the wind speed cubed, higher wind speeds produce exponentially more energy than lower wind speeds.
We calculate wind speed distribution using a mathematical tool called the Weibull Curve. It can be used to model a wide range of distribution curves just by supplying a couple of input variables.
