The Impact Of Reduced Arctic Sea Ice Extent On Cryospheric Snowfall, Alexander Carne
The Impact Of Reduced Arctic Sea Ice Extent On Cryospheric Snowfall, Alexander Carne
Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research
Satellite observations show that sea ice extent in the Arctic has been declining from 1979 through present day, reaching record minimum extents in 2007 and 2012. Reduced sea ice extent allows for greater expanses of open water to interact with the Arctic atmosphere, potentially leading to changes in the Arctic climate. The greatest declines in Arctic sea ice extent have occurred in summer and autumn. During these seasons, it is likely that the decrease in Arctic sea ice extent led to an increase in atmospheric sensible and latent heat fluxes, possibly leading to increases in Arctic temperature and moisture. Increases …
