“…Es posible ampliar aún más el conocimiento del origen y la física de las olas gigantes mediante el análisis de bases de datos de mediciones de oleaje confiables. El problema es que son limitadas las mediciones de campo disponibles que proporcionan información del origen y la física de las olas gigantes, ya que son pocos los estudios que se han llevado a cabo con datos de campo (e.g., Chien et al 2002, Mori et al 2002, Silva et al 2002, Stansell 2004, Sulisz y Paprota 2005, Didenkulova 2010, Montoya et al 2013.…”

Freak waves are unique phenomena that appear unexpectedly on the ocean surface. These waves are not only a danger to fishermen and yachtsmen, but are also capable of damaging large vessels and offshore and coastal structures. The available field measurements that provide insight into the origin and physics of freak waves are very limited. The main objective of the present study was to analyze a unique set of wave data comprising 19,025 wind-wave records from the southern Baltic Sea to provide information on the occurrence, parameters, and prevailing conditions of the formation of freak waves. The complex nature of freak waves was investigated by obtaining spectral and statistical parameters of freak-wave-prone sea states using a wide set of tools. The study revealed a large number of freak-type waves, including waves over 12 m high. The study indicates that these hazardous waves may even exceed 20 m during severe storms in the Baltic Sea. Multi-point wind-wave measurements are needed to provide more information about the physics of freak waves and to eventually develop a prediction or warning system to avoid casualties.

“…In general, the model predicted parameters Hs and Tc as shown in Figure 12 reveal very good correlation with the observations in most cases. Korres et al [33] and Montoya et al [37] have reported that, WWIII performed well showing best statistical estimates with the observedwave parameters such as Hs and Tc for the Mediterranean Sea and Gulf of Mexico respectively. In this case, the buoy observations such as DS1, DS2, SW1 and SW4 in the Arabian Sea versus the model hindcasts for Hs indicate correlation coefficients of the order 0.90 to 0.97, while in theBay of Bengal, it is 0.98 for SW5.…”

“…The WAVEWATCH-III (WW3) model developed by the National Centers for Environmental Prediction (NECP) of the National Oceanic and Atmospheric Administration (NOAA) is a third-generation model in the spirit of the previous WAM model [7] with explicit treatment of the nonlinear term. Recent research has confirmed that the WW3 model has the capacity to simulate waves in the Pacific Ocean [8][9][10], the China Seas [11][12][13] and other critical seas [10,14,15] and it has a good performance when validating the simulations against moored buoys and satellite altimeter measurements [16]. Moreover, the WW3 model is also useful for wave climate analysis [17,18].…”

Abstract:The Beibu Gulf is an important offshore region in the South China Sea for the fishing industry and other human activities. In 2017, typhoons Doksuri and Khanun passed the Beibu Gulf in two paths, at maximum wind speeds of up to 50 m/s. Typhoon Doksuri passed the Beibu Gulf through the open waters of the South China Sea and Typhoon Khanun moved towards the Beibu Gulf through the narrow Qiongzhou Strait. The aim of this study is to analyze the typhoon-induced wave distribution in the Beibu Gulf. WAVEWATCH-III (WW3) is a third-generation numeric wave model developed by the National Oceanic and Atmospheric Administration (NOAA), which has been widely used for sea wave research. The latest version of the WW3 (5.16) model provides three packages of nonlinear term for four wave components (quadruplets) wave-wave interactions, including Discrete Interaction Approximation (DIA), Full Boltzmann Integral (WRT), and Generalized Multiple DIA (GMD) with two kinds of coefficients, herein called GMD1 and GMD2. These four packages have been conveniently implemented for simulating wave fields in two typhoons after taking winds from the European Centre for Medium-Range Weather Forecasts (ECMWF) at 0.125 • grids as the forcing fields. It was found that the GMD2 package was the recommended option of the nonlinear term for quadruplets wave-wave interactions due to the minimum error when comparing a number of simulated results from the WW3 model with significant wave height (SWH) from ECMWF and altimeter Jason-2. Then the wave distribution simulated by the WW3 model employing the GMD2 package was analyzed. In the case of Typhoon Doksuri, wind-sea dominated in the early and middle stages while swell dominated at the later stage. However, during Typhoon Khanun, wind-sea dominated throughout and swell distributed outside the bay around the east of Hainan Island, because the typhoon-induced swell at mesoscale was difficult to propagate into the Beibu Gulf through the narrow Qiongzhou Strait.
