中文摘要：

在西北太平洋(NWP ) 形成的热带气旋(TC ) 能有时穿过华南海(SCS ) 。在在 11 月的 SCS 的 TC 轨道在 1980 前与那些相比在 1980 以后被转移到北方，这被发现。数据分析和数字模拟证明在 SCS 温暖的表面可以更向北方贡献这移动。温暖在西北的 SCS 生产一个气旋的空气发行量异例并且一联系在驾驶 TC 到北方的中央 SCS 南方。

英文摘要：

Tropical cyclones （TCs） formed in the Northwest Pacific Ocean （NWP） can cross the South China Sea （SCS） sometimes. It is found that the TC tracks in the SCS in November are shifted to the north after 1980 compared with those before 1980. Both data analyses and numerical simulations show that the surface warming in the SCS may contribute to this more northward shift. The warming produces a cyclonic atmosphere circulation anomaly in the northwestern SCS and an associated southerly in the central SCS steering the TCs to the north.
