| 摘要: |
| 北部湾潮致余流的流速只有1~2cm/s左右,靠近海南岛一侧,潮致余流的环流基本为气旋式:分别位于洋浦以北、东方以西、莺歌海西南方。只有靠近越南红河口,有一个反气旋涡;风生海流呈现冬季模式和夏季模式。冬季,表层19°N以北为西南向的流动,19°N以南,靠近海南岛水域为西向流动,越南沿岸为南向流动。大部分区域流速为5~12cm/s,流速最大位于琼州海峡西面及海南岛西南部,可达10~20cm/s,底层流速明显比表层小。夏季,表层,大部分海区为东北向流动,海南岛以南的海区为向东流动,流速大都在3~7cm/s,越南沿岸和海南岛西岸及西北沿岸流速为7~9cm/s,最大流速出现在海南岛西和西北沿岸,可以达到12cm/s。底层,大部分地区流速均小于1cm/s。 |

| Abstract: |
| The velocity of tide-induced residual currents in Beibu Bay is about 1~2cm/s.Near Hainan island, cyclonical circulations of residual currents are located on the north of Yangpu, west of Dongfang and south-west of Yingge Sea respectively.There is an anti-cyclonical eddy near estuary of Hong river in Vietnam.Wind-driven current presents different models.In winter, the surface current on the north of 19°N is mainly SW, while westward near Hainan island and southward in Vietnam coastal on the south of 19°N.In most area the velocity is 5~12cm/s and the maximum is 10~20cm/s appearing on the west of Qiongzhou strait and south-west of Hainan island.The bottom velocity is obviously small than the surface velocity.In summer, the surface current in most area is mainly NE, while eastward (3~7cm/s) on the south of Hainan island.The velocity is 7~9cm/s in Vietnam coastal and on the west and north-west of Hainan island, and the maximum is 12cm/s appearing on the west and north-west of Hainan island.The bottom velocity is mostly small than 1cm/s. |
