Influence of sea ice on Arctic precipitation.
Global climate is influenced by the Arctic hydrologic cycle, which is, in part, regulated by sea ice through its control on evaporation and precipitation. However, the quantitative link between precipitation and sea ice extent is poorly constrained. Here we present observational evidence for the response of precipitation to sea ice reduction and assess the sensitivity of the response. Changes i...
متن کاملArctic sea ice reconstructions
Can we reconstruct Arctic sea ice back to 1900 with a hybrid approach? S. Brönnimann, T. Lehmann, T. Griesser, T. Ewen, A. N. Grant, and R.

متن کاملHow does sea ice influence δ18O of Arctic precipitation?
This study investigates how variations in Arctic sea ice and sea surface conditions influence δ18O of presentday Arctic precipitation. This is done using the model isoCAM3, an isotope-equipped version of the National Center for Atmospheric Research Community Atmosphere Model version 3. Four sensitivity experiments and one control simulation are performed with prescribed sea surface temperature ...
متن کاملInfluence of ice thickness and surface properties on light transmission through Arctic sea ice
The observed changes in physical properties of sea ice such as decreased thickness and increased melt pond cover severely impact the energy budget of Arctic sea ice. Increased light transmission leads to increased deposition of solar energy in the upper ocean and thus plays a crucial role for amount and timing of sea-ice-melt and under-ice primary production. Recent developments in underwater t...
متن کاملThe early twentieth century warming and winter Arctic sea ice
The Arctic has featured the strongest surface warming over the globe during the recent decades, and the temperature increase has been accompanied by a rapid decline in sea ice extent. However, little is known about Arctic sea ice change during the early twentieth century warming (ETCW) during 1920–1940, also a period of a strong surface warming, both globally and in the Arctic. Here, we investi...
