Numerical Simulation of Tropical Cyclones and Storm Surges in the Arabian Sea

Abstract

Winds, waves and storm surges of Gonu and Ashobaa, as two recent cyclones in the Arabian Sea and Gulf of Oman, are simulated by a system of WRF-FVCOM-SWAN. The employed models are separately calibrated using the available data. Surges are found to be highly dependent on coastal geometry and landfall location, rather than the storm intensity. Comparisons at different stations reveal that the results of models are in a good agreement with measured parameters. Negative surges are also observed in the enclosed basins of the Persian Gulf and Red Sea. The calibrated atmosphere-wave-ocean model can be utilized for the prediction of extreme events, expected to increase in future due to the impact of the climate change.

Waves and Storm Surges of Tropical Cyclones Over the Arabian Sea: Future Projections and Uncertainty Analysis

“…The boundary condition (red line in Figure 1), is selected from WWIII data (MMAB, 2016) and TPXO atlas model (Egbert and Erofeeva, 2002), for SWAN and FVCOM models, respectively. Model calibration is conducted using the measurements of local waves and storm surges in the baseline periods (Soltanpour et al, 2018).…”
