基于三维水动力海洋数值模型的莫桑比克海峡潮汐数值模拟OA

The Mozambique Channel is the longest channel in the world,with unique tidal wave dynamic characteristics.This study simulates the tidal dynamic processes in the Mozambique Channel using the Finite-Volume Community Ocean Model(FVCOM).Numerical experiments are conducted with different drag coefficients,seamount morphologies,and coastline characteristics.The results show that the tidal wave system in the Mozambique Channel and its adjacent sea areas are dominated by the semi-diurnal tides M2 and S2,and the maximum tidal current energy occurs at the narrowest part of the Mozambique Channel.The narrowing effect of the horn-shaped coastline in the northern part of the channel has the greatest impact on the tidal energy flux.The depth and location of seamounts can modulate the tidal energy flux slightly,while the bottom friction has a negligible impact on the tidal energy flux.
