عنوان انگلیسی Investigation the Surface Waves During the Indian Ocean Summer Monsoon in the Chabahar Offshore Area Using Numerical Modeling
چکیده انگلیسی مقاله Spectral and statistical analyses of wind-induced waves are very important in the design of coastal and offshore structures. In this study. the results of numerical simulations by two spectral wave models (MIKE SW and SWAN) were compared to investigate the effect of the Indian Ocean summer monsoon on wave patterns in the Chabahar offshore area in the northern Gulf of Oman. The wind field for the wave simulations was obtained by the WRF model. WRF and SWAN were implemented as wave-atmosphere subsystems of the COAWST (Coupled Ocean–Atmosphere–Wave–Sediment Transport model). For MIKE SW wind input. the output wind field of the WRF model was extracted and converted to the readable format. The results of the wave simulation are acceptable by both the COAWST and MIKE SW experiments in comparison with observational data. but the results of the COAWST model were more accurate than the results of MIKE SW in simulating wave height and period. while in simulating wave direction. MIKE SW was more accurately than COAWST. The wave spectrums were prepared for observational data and model results. All Spectrums had a single peak which means that one main frequency is responsible for the most wave energy. The best-fitted spectrum was JONSWAP for all occasions. This means that the sea state of the study area was not a fully developed sea during the simulation period. Directional wave spectrums of observational data and model results showed the south and southeast directions for the wave energy propagation.
