3: Physical processes <strong>of</strong> <strong>SWAN</strong><br />
<br />
We only take the expressions <strong>of</strong> wind and whitecapping into<br />
consideration in our experiments.<br />

Wind energy to <strong>wave</strong>s is commonly described as the sum <strong>of</strong> linear<br />
and exponential growth. There are two kinds <strong>of</strong> wind growth<br />
<strong>model</strong>s in <strong>SWAN</strong> that are available for us. Both expressions <strong>of</strong><br />
wind growth <strong>model</strong> <strong>of</strong> them share the following form (1) and the<br />
same linear growth (2), while the exponential growth term is<br />
different.<br />
S in<br />
( σ , θ ) = A + B × E(<br />
σ , θ )<br />
A describes linear growth and B×E describes exponential growth.<br />
