湄洲湾海水交换率和半更换期的计算

Computation of the Turn-over Rate and the Half Exchange Period of Seawater in Meizhou Bay

利用湄洲湾海域现场观测数据,采用单箱模型,二线数值模型分别计算了湄洲湾海水的平均交换率,平均半更换期和各区段海水的半更换期,计算结果表明:湄洲湾海水的平均交换率为0.127,平均半更换期为7.1d,湾顶附近水域的半更换期超过19d。

Based on the marine investigation data,Box model and Two-dimensional numerical mode) are used in the computation of the average turn-over rate,half exchange period in Meizhou Bay. The computed results show that the average turn-over rate of Meizhou Bay is about 0. 127,average half exchange period is 7. 1d and half exchange period in the bead of the Meizhou Bay is over 19d.
