罗斯海和普里兹湾海域海冰范围变化对比分析
COMPARATIVE ANALYSIS OF CHANGES IN SEA ICE EXTENT IN ROSS SEA AND PRYDZ BAY
摘要
Abstract
Changes in sea ice extent have a significant impact on climate change,ecosystems,and human activities,and the change in polar sea ice extent has created major concern in recent years.In this paper,sea ice extent in the Ross Sea and Prydz Bay in Antarctica were compared using time-series analysis.There were distinct differences in the patterns of seasonal variation in sea ice extent between the Ross Sea and Prydz Bay.The Ross Sea showed rapid decrease-rapid growth,while Prydz Bay showed rapid decrease-slow growth.However,annual variations in sea ice extent in both regions are increasing.The annual trend in the Ross Sea was (1 .39 ±1 .1 2)×1 04 km2 ·a -1 while in Prydz Bay the trend was (0.61 ±0.26)×1 04 km2 ·a -1 .The annual growth of winter sea ice extent was higher than that of summer sea ice extent in both areas,and the annual trend in the Ross Sea region showed negative growth in summer sea ice extent.关键词
