The bin averaged gust size, as a function of wind speed is shown on Figure 5.3 a, where<br />

only a small amount of d<strong>at</strong>a is recorded <strong>at</strong> wind speeds above 35 m/s (during the<br />

December storm in 1999).<br />

The distributions of 5-s gusts <strong>at</strong> level 62 m have been determined for 4 different wind<br />

speed intervals (V > 10 m/s) based on the figures given in Table 5.3.<br />

Table 5.3 Number of hours in each wind speed interval<br />

Interval Hours<br />

10 < V < 15 m/s 8506 hours<br />

15 < V < 20 m/s 2791 hours<br />

20 < V < 25 m/s 365 hours<br />

25 < V 47 hours<br />
