| Zusammenfassung |
| The wave statistical parameters during Cyclone Phailin which crossed the
northern Bay of Bengal are described based on the Directional Waverider
buoy-measured wave data from 8 to 13 October 2013. On 12 October 2013, the cyclone
passed within 70 km of the Waverider buoy location with a wind speed of
59.2 m s−1 (115 knots), and during this period, a maximum significant wave
height of 7.3 m and a maximum wave height of 13.5 m were measured at 50 m
water depth. Eight freak wave events are observed during the study period.
The ratio of the maximum wave height to significant wave height recorded
is found to be higher than the theoretical value and the ratio of the crest
height to wave height during the cyclone was 0.6 to 0.7. The characteristics
of the wave spectra before and after the cyclone is studied and found that
the high-frequency face of the wave spectrum is proportional to f−3
before the cyclone and is between f−4 and f−5 during the cyclone
period. |
