Arctic Sea Level Variation in the Context of Climate Change: Accelerated rise period and Change of Key Influencing factors
This study finds that sea level height in Arctic marginal sea in melting season enters an accelerated rise period since the beginning of the 21st century. It is found that precipitation is the dominant factor affecting the change of sea level height in melting season in 1979-1998. Polar vortex and A...
