| Abstract: | In view of complex multi-island terrain in archipelagic sea areas, the paper designs a computational scheme to optimize computational grid by integrated utilization of water depth data and high-resolution coastline data with an introduction of topographic subgrid-scale effect. Numerical tests under the two typical weather conditions of cold air and typhoon in Ryukyu Islands were conducted using the WAVEWATCH - Ⅲ model. Results were compared with measured data. Results showed that different computational schemes of complex multi-island terrain were the major sources of errors of wave numerical simulation in archipelagic sea areas. Scheme in this paper gave full consideration to the effect of coastal and multi-island terrain on wave propagation, and numerical calculation results were obviously improved. |
