| Zusammenfassung |
| The nonlinear and nonstationary properties of a special field wave record
are analysed with the Wigner spectrum with the Choi–Williams kernel. The
wave time series, which was recorded at the Ekofisk complex in the central
North Sea at 00:40 UTC (universal time coordinated) on 9 November 2007, contains an abnormally high
wave known as the "Andrea" wave. The ability of the Wigner spectrum to reveal
the wave energy distribution in frequency and time is demonstrated. The
results are compared with previous investigations for different sea states
and also the state with Draupner's abnormal "New Year" wave. |
