摘要
Based on the monthly average sea level data from the tide gauge measurement(1999-2001), the seasonal variability of the sea level in the Northern and Middle Yellow Sea isstudied to reveal that the sea surface height at all the tide gauges becomes higher in summer thanthat in winter. In addition, the sea surface height of the Northern Yellow Sea is higher than theone of the Middle Yellow Sea with a slope downward from the north to the south in summer, while itis lower with a reversed slope in winter. The seasonal reverse of the sea surface slope can beattributed to the monsoon effects i. e. the annual reverse of the monsoon direction and the annualvariation of the monsoon rainfall. A set of equations are established in light of the dynamicprinciples to expound how the monsoon forcing and the sea surface slope generate a summer outflowand a winter inflow in the Yellow Sea.
