An example of measured 3-D time series including sonic temper<strong>at</strong>ure is shown in<br />

Figure 3.6. This time series contains a (large) gust of approx. 10 m/s and with a<br />

skewness of 2.8; a gust of this n<strong>at</strong>ure is however not severe to any wind turbines,<br />

because the gust rise time is r<strong>at</strong>her long (>40 s).<br />
