Abstract

Atmospheric rivers (ARs) serve as mechanisms that transport water vapor to the poles, triggering extreme weather events, altering weather patterns over Greenland, and even impacting mass changes in the Greenland ice sheet. In this study, we detected and extracted ARs spatiotemporal evolution characteristics over Greenland from the past two decades. And subsequently analyzed the Greenland mass changes. Our findings indicate that between 2000 and 2019, the annual occurrences of ARs varied from 13 to 27 times, with durations ranging from 156 to 610 h. Interestingly, the ARs exhibited distinct migration patterns across different periods, transitioning from a uniform distribution towards the west side of Greenland and eventually towards the east side. To delve deeper into the relationship between ARs and mass changes, we assessed the contribution of ARs to Greenland's surface mass balance using a five-year study period. The results show that the contribution of AR to SMB has a tendency to increase in stages, 20.5% from 2000 to 2004, 31.5% from 2005 to 2009, 46.4% from 2010 to 2014, and 48.2% from 2015 to 2019.

期刊介绍： Polar Science is an international, peer-reviewed quarterly journal. It is dedicated to publishing original research articles for sciences relating to the polar regions of the Earth and other planets. Polar Science aims to cover 15 disciplines which are listed below; they cover most aspects of physical sciences, geosciences and life sciences, together with engineering and social sciences. Articles should attract the interest of broad polar science communities, and not be limited to the interests of those who work under specific research subjects. Polar Science also has an Open Archive whereby published articles are made freely available from ScienceDirect after an embargo period of 24 months from the date of publication. - Space and upper atmosphere physics - Atmospheric science/climatology - Glaciology - Oceanography/sea ice studies - Geology/petrology - Solid earth geophysics/seismology - Marine Earth science - Geomorphology/Cenozoic-Quaternary geology - Meteoritics - Terrestrial biology - Marine biology - Animal ecology - Environment - Polar Engineering - Humanities and social sciences.
