渤黄东海40年温盐流模拟与初步分析

使用ROMS(regional oceanic modeling system)模式模拟了40年的渤黄东海温盐流，数据包括三维的温度、盐度、流速、流向和海表高度，同时包含了逐小时的潮汐信息。将模拟结果与观测资料和卫星反演数据进行对比，检验了模式准确性。整体上，模式模拟的水位与近岸观测值基本一致，能够准确再现风产生的增水；模式较为准确的再现了渤黄东海的温度分布，在深水区模拟的温盐剖面与观测值基本一致；模式模拟渤黄东海区域的海表高度和海表流与卫星反演结果相比偏小，但分布趋势相近。模式结果可以为研究气候变化对水位的影响和黄海暖舌的扩散过程等现象提供数据支持。

Modeling of temperature, salinity and current in Bohai Sea, the Yellow Sea and the East China Sea based on 40 year data

In this paper, ROMS(regional oceanic modeling system) is used to simulate the temperature, salinity and current variations in Bohai sea, the Yellow Sea and the East China Sea using 40 year data with hourly tidal information. The output includes three-dimensional temperatures, salinities, velocities and sea level heights as well. These results were verified by comparing the simulated results with the observation and remote sensing data. It shows that the simulated water level is in good agreement with the observatories, including an accurate reproducing of the water level variations influenced by winds. The model accurately reproduces the temperature distribution in Bohai Sea, the Yellow Sea and the East China Sea. Also, the simulated thermohaline profiles in the deepwater area are consistent with the observed values. Compared with remote sensing data, the sea surface heights and sea surface currents simulated by the model are smaller, but the distribution patterns are similar. These model results can provide data support for studying the influence of climate change on water level and the diffusion process of warm tongue in the Yellow Sea.
