1. 1. The mutual interaction between the time-mean atmospheric circulation and continental-scale ice sheets

   Författare :Johan Liakka; Johan Nilsson; Johan Kleman; Gerard Roe; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Atmospheric stationary waves; Paleo ice sheets; Ice-sheet ablation; Atmosphere-ice sheet modelling; Climatology; Klimatologi; Meteorology; Meteorologi; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Sammanfattning : Geomorphological evidence of glaciations exist for the Last Glacial Maximum (about 20 kyr ago). At this time, both North America and Eurasia were covered by extensive ice sheets which are both absent today. LÄS MER

3. 2. On the interaction between ice sheets and the large-scale atmospheric circulation over the last glacial cycle

   Sammanfattning : The last glacial cycle (c. 115-12 kyr BP) was the most recent in a series of recurring glaciations of the subpolar continents. Massive ice sheets evolved in Eurasia and North America, which, at their maximum, were of continental scale and together lowered the global sea-level by approximately 100 m. LÄS MER
