Relationships between Arctic sea-ice concentration, temperature, and specific humidity in the lower troposphere during 1980–2021

Abstract. Understanding of the local effects of sea-ice concentration (SIC) variations on the Arctic atmosphere is a prerequisite for assessing the role of Arctic sea-ice decline in the climate system, including its influence on mid-latitudes. In this study, we analysed the relat...

On the relevance of serial cyclone clustering for Arctic sea ice

Abstract Short-term changes in Arctic sea-ice concentration (SIC) are largely driven by weather, and strong ice loss typically occurs during intense Arctic cyclones causing unusually warm and stormy conditions. Such conditions are prolonged when several cyclones follow rapidly on...
