Abstract/Summary

Due to the threat of global warming, extensive studies of the natural and anthropogenic causes of sea level change have been performed. The use of satellite altimetry contributes enormously to such studies, especially where in situ observations are rare. This chapter highlights the authors’ recent investigations of sea level measurements in the China seas made by satellite altimetry. Different sea level components are investigated. Progress is being made towards a better estimation of the ocean tides in the China seas using a comprehensive combination of satellite altimetry products. The seasonal sea level cycle, another crucial component of sea level in the China seas, is also systematically studied by using different analysis approaches. We finally explore the long-term trends and variability of mean sea level by analyzing the latest (1993–2016) satellite altimetry. The relationships between mean sea level and large-scale ocean circulation and climate variability are also examined.
