  7. Abstract:
  8. Super cyclone GONU formed on June 2007 has been recognized the strongest tropical cyclone in the North Indian Ocean (NIO). The aim of this study is to numerically simulate the cyclone GONU and its resulting waves in the southern seas of Iran leading to the best parametric model to simulate future occurrence of tropical cyclones (TCs) in the NIO. In this regard, the best track data of the cyclone is extracted from Indian Meteorological Department (IMD). The cyclone GONU wind field is simulated by Young and Sobey, Holland, and Rankin models in order to determine the most appropriate model which is then considered for regenerating cyclonic wind fields over the Makran coastline and the sea of Oman. Afterwards, by using Spectral Wave (SW) model and appropriate wind field, wave fields of cyclone GONU is simulated. Based on the results, the Rankin model is considered to be the most suitable model applied for the simulation of cyclone GONU. Moreover, the difference of 2 % between the significant wave height (H1/3) of the investigated cyclone and that from Chabahar buoy of Oceanic and Atmospheric Science Centre (OASC) is observed. To conclude, the results from this study not only provide valuable bed for designing offshore and coastal structures, but also make the study of great importance to estimate significant wave height originated in probable future cyclones and delivering imperative data to forecast future scenarios
