This paper presents modelling the wave conditions in Typhoon Krosa prior to
touching Taiwan in October 2007, with third-generation wave models of SWAN
and WWM. The accuracy of the extreme wave measurement Hmax = 32 m
with significant wave height Hs ≈ 24 m at the depth of
h = 38 m is discussed first. It is concluded that the measurement does not
appear faulty and is physically realistic. The numerical results are then
analysed in order to examine the models' capability to reproduce the observed
conditions. It is found that neither SWAN nor WWMII are able to hindcast the
extreme measurement. Series of sensitivity tests are conducted for different
numerical and diffraction schemes, and source functions. It is shown that, in
the circumstances, the model performance only improves in response to the
bottom-limited breaking formulation. |
