Study of the Gonu Tropical Cyclone in the Arabian Sea

Abstract

ABSTRACT Mashhadi, L.; Zaker, N.H.; Soltanpour, M., and Moghimi, S., 2015. Study of the Gonu tropical cyclone in the Arabian Sea. The waves created in the Arabian Sea by the Gonu tropical cyclone have been simulated in this paper by employing the Simulating Waves Nearshore (SWAN) third-generation spectral wave model. The model was established in a nonstationary mode. The linear and exponential growth from the wind input, the wave–wave nonlinear interaction, the whitecapping, and the bottom friction were considered in the simulation. The model results are compared with data measured at three stations on the Chahbahar Bay, which is located in the south of Iran. The significant wave height, the peak wave period, and the mean wave direction are the three key peak features taken into account. The results show that the significant wave height and the mean wave direction can be reasonably predicted. However, the simulated peak wave period is underestimated. The distribution of the wave fields is obtained to asse...
