1. 1. Shallow near-surface lapse rates and their connection to glacier meteorology on Storglaciären and Rabots glaciär, Northern Sweden

   Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

   Författare :Moon Taveirne; [2022]
   Nyckelord :Temperature lapse rate; glacier meteorology; near-­surface lapse rate; ablation gradient;

   Sammanfattning : Glacier melt is strongly impacted by climate and meteorology. Temperature lapse rates are used to model glacier melt, and the accuracy of the spatial distribution of modelled melt can be impacted by the lapse rate used in modelling. Additionally, the observed spatial distribution of melt is highly temporally variable. LÄS MER

3. 2. Analysis of the Temporal Variability of Positive Degree Day Factors

   Kandidat-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

   Författare :Hanna Rönnberg; [2016]
   Nyckelord :Positive Degree Day Surface Mass Balance; Physics and Astronomy;

   Sammanfattning : The surface mass balance determines the growth or decay of an ice sheet, by taking the difference between accumulation and ablation. In this thesis snow and ice ablation is related to 2m-temperature through the positive degree day method. LÄS MER
