摘要 利用POM海洋数值模式建立了中国近海(2°N^41°N,99°E^132°E)分辨率为5′×5′的潮汐模型,模式采用b lend ing同化法同化了由10年TOPEX/Pose idon测高数据反演的潮汐参数与沿岸52个验潮站观测。精度分析表明建立的潮汐模型的8分潮RSS为12.5 cm。 A regional tide model around China (2°N-41°N,99°E~132°E) with a spatial resolution of 5′ has been developed. The "blending" assimilation method is implemented to assimilate 10 years of TOPEX/ Poseidon altimeter data and 52 gauges into POM model. Comparison of the tide model with tide gauge data shows that the RSS of 8 constituents is 12.5 cm. The performance is better than those of the global ocean tide model around China.
