where
E
denotes the mean operator. The kurtosis is a higher-order measure
to identify non-Gaussian characteristics of a wave field. For a Gaussian sea
state (i.e. linear and random waves) the kurtosis is 0. Usually you will not
include this quantity in your model output specifications.
Atiltness
The atiltness
A
is defined by
(5.13)
where
E
denotes the mean operator. The atiltness is a higher-order integral
measure of the lack of vertical wave profile symmetry. The parameter takes a
positive value when the wave profile are tilted forward (like in the shoaling
zone) and takes a negative value when tilted backward. For further informa-
tion on this output type please see Goda and Morinobu (1998) p. 314ff.
Usually you will not include this quantity in your model output specifications.
