罗斯海和普里兹湾海域海冰范围变化对比分析
|
摘要
海冰范围的变化对气候变化、生态系统以及人类活动都会产生重大的影响,近年来极地海冰范围的变化受到广泛关注。对南极罗斯海与普里兹湾海域海冰范围进行时间序列分析,研究发现海冰范围季节性变化在罗斯海与普里兹湾海域差异较大,罗斯海地区表现出"快速缩小、迅速扩大"的特性,普里兹湾海域表现出"快速缩小、缓慢扩大"的特性。两地区的海冰范围在年际变化上都表现出扩大的趋势,2003—2014年罗斯海地区海冰变化趋势为(1.39±1.12)×104km2·a~(-1),普里兹湾海域海冰变化趋势为(0.61±0.26)×104km2·a~(-1)。罗斯海地区夏季的年际变化为减少趋势。
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. 12) × 104km2·a~(-1)while in Prydz Bay the trend was( 0. 61 ± 0. 26) × 104km2·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.
