“…Atmospheric aspects and oceanographic responses to Gonu have been studied by different researchers (Fritz et al [21]; Krishna and Rao [22]; Dibajnia et al [23]; Wang et al [24]; Mashhadi et al [20]). Dibajnia et al [23] used the 3rd generation WAVEWATCH-III wave model to simulate the wave field generated by Gonu in the northern Oman Sea and along the Iranian coasts.…”

The third generation wind-wave model Mike21-SW was used to study spectral characteristics of waves generated by the historical Cyclone Gonu in June 2007 along and off the Iranian coasts on the northern Oman Sea. The model was forced with the cyclone wind field generated using a Holland (1980) model based on cyclone data obtained from the Joint Typhon Warning Center (JTWC). The wave model was calibrated for the northern Oman Sea using bulk and spectral wave data at a station out of the Chabahar Bay. Evolution of directional-frequency spectra during the cyclone was investigated for two locations near the entrance and off the Chabahar Bay. At the offshore station, energy was contributed to the spectrum over an approximately 180 degree directional span that included different local and remotely generated waves. As the cyclone proceeded northwestward, all spectral directions continuously rotated in the clockwise direction at both locations. Frequency spectra at these locations were investigated for four different times corresponding to different locations of Cyclone's eye and were justified using the sea growth parameter of the Joint North Sea Wave Project (JONSWAP) experiment. Using the modified JONSWAP parameters for hurricane conditions resulted in a frequency spectrum consistent with simulation results.

“…These ejections were related to the presence of mesoscale eddies in the Sea of Oman, and especially to the presence of a dipole in spring; different offshore ejection mechanisms were identified. PGW ejection was also identified in response to tropical atmospheric cyclones (in particular cyclone Gonu; Wang et al, 2012Wang et al, , 2013.…”

“…Indeed, in October-November 1999, during the fall intermonsoon, the GOGP99 1 experiment at sea sampled the PGW outflow and identified it as a coastal flow, extending to the southern coast of Oman (see Pous et al, 2004). During other seasons, the path of the PGW in the Gulf of Oman is less regular, as shown by observations and by numerical modeling; also, PGW can exit in the form of short pulses (see Banse, 1997;Senjyu et al, 1998;Bower et al, 2000;Prasad et al, 2001;Thoppil and Hogan, 2009;Wang et al, 2012;Wang et al, 2013). Recently, ARGO floats (see Carton et al, 2012;L'Hégaret et al, 2013) and HYCOM numerical simulations (see L'Hégaret et al, 2015) confirmed that during other seasons, PGW can be expelled from the coast into the Sea of Oman.…”

“…The observing system provided the only in situ current, salinity, temperature, and dissolved oxygen observations directly under the storm. The observations show that the principal oceanic response in the Oman Sea was the combination of three different frequency oscillations with periods of near-inertial, subinertial (2-10 days), and low-frequency variability (12.7 days) [Wang et al, 2012]. In the deep basin near Murray Ridge the deep (3000 meters) oceanic response exhibited the characteristics of a topographic bottom-trapped subinertial wave [Wang et al, 2012].…”

An ocean observatory—consisting of a real‐time, cabled array in the Sea of Oman and an internally recording, autonomous mooring array recently upgraded to a cabled array in the northern Arabian Sea—celebrated more than 2500 days of continuous operation in July 2012. The observatory, which measures a range of properties, such as water current velocities, temperature, salinity, pressure, dissolved oxygen, and turbidity, is part of the Lighthouse Ocean Research Initiative (LORI) project [du Vall et al., 2011], which was designed as a pilot project and installed in 2005 in the region off Abu Bakara (Figures 1a and 1b). The initial goal of the project was to prove that an in situ, cabled ocean observatory can return high‐quality scientific data on a real‐time basis over longer time periods than conventional moored systems. That same year, an autonomous array was deployed off Ras al Hadd and on Murray Ridge in the Arabian Sea (Figure 1a).
