We investigated material transport from the East China Sea to the Japan Sea based on field observation, and spatial and temporal variation in sea surface current field using satellite altimetry data. It was found that interannual variation in material transport from the East China Sea to the Japan Sea was quite large, and the variability was caused by the change of current field in the East China and Yellow Seas. We revealed characteristics of sea surface current variation in the East China and Japan Seas using satellite altimetry data. Moreover, we developed a tidal assimilation model in order to improve the accuracy of the altimetry data in the East China and Yellow Seas.

在野外观测的基础上，利用卫星测高资料研究了东中国海向日本海的物质输送和海面流场的时空变化。研究发现，从东中国海到日本海的物质输送年际变化较大，这种变化是由东中国和黄海的流场变化引起的。利用卫星测高资料揭示了东中国和日本海表层海流的变化特征。此外，为了提高东中国和黄海测高资料的精度，我们还发展了一个潮汐同化模式。
