利用卫星高度计资料，发现南海北方的地形陷波（TTW）沿沿着陆架传播。TTW在经过东沙群岛时明显减速。利用考虑地形影响的准地转方程，我们发现东沙群岛引起的地形梯度决定了TTW的传播速度，导致TTW的减慢。
Based on the satellite altimeter data, it is found that the topography trapped wave (TTW) propagates along the continental shelf in the northern South China Sea (NSCS). The TTW obviously slows down while passing by the Dongsha Islands. Using a quasi-geostrophic equation including the topography effect, we found that the topographic gradient induced by the Dongsha Islands determines the propagation speed, leading to the slowdown of the TTW.
