Mean Wave Hight<br />
Figure 6.7 Probability distributions of mean wave height Hmean<br />
Since waves are gener<strong>at</strong>ed by the wind shear and wind pressure on the sea surface, a<br />
clear dependency on these two phenomena can be expected. Figure 6.9 illustr<strong>at</strong>es this<br />
rel<strong>at</strong>ionship between the wind speed (1 hour average) in level 62 and the significant<br />
wave height Hm0. In addition to the wind speed it is evident from this figure th<strong>at</strong> also the<br />
fetch plays an important role for the wave gener<strong>at</strong>ion, waves being smaller from eastern<br />
directions where the fetch is limited (15–40 km). The pronounced sc<strong>at</strong>ter in the figure<br />
can mainly be contributed to the fact th<strong>at</strong> the waves do not react instantaneously to fast<br />
changes in wind speed.<br />
