摘要
利用FVCOM海洋数值模式计算了印尼近海的M2,S2,K1,O1分潮的分布,计算范围从20°S~20°N,90°~150°E,计算网格分辨率在印尼海域岛屿平均为1/12度,在大陆边界平均为1/5度,在开边界平均为1/2度。计算结果与104个TOPEX/Poseidon卫星高度计交叉点数据和79个验潮站数据进行比较,符合良好;与高度计交叉点比较,M2分潮振幅的均方根差为6cm,迟角为7°;S2分潮的振幅偏差为3cm,迟角偏差为8°;K1分潮振幅的偏差为6cm,迟角偏差为10°;O1分潮振幅偏差为3cm,迟角偏差为10°。根据计算结果给出了4个分潮的潮汐、潮流、潮余流和潮能通量密度分布图。
The principal tidal constituents, M2, $2, K2 and O1, in the Indonesian adjacent seas are numeri- cally simulated using the FVCOM ocean model. The computational domain covers an area from 20°S-20°N, 90°-150°E. The averaged model resolution is 1/12 degree near small islands in the Indonesian adjacent seas, 1/5 degree near the mainland coasts and 1/2 degree near the open boundary. The model results are compared with the observations at 104 TOPEX/Poseidon (T/P) crossover points and at 79 tide gauge sta- tions, showing a satisfactory agreement. Comparing with the observations at T/P crossover points, the root-mean-square (RMS) deviations in amplitude and phase-lag are respectively 6 cm and 7° for M2, 3 cm and 8° for $2, 6 cm and 10° for K1 and 3 cm and 10° for O1. Based on the model results, the distributions of tides, tidal current ellipses, tidal residual eurrents and tidal energy flux density vectors of the 4 tidal constituents, i.e. M2, S2, K1 and O1, are presented.
