1. 1. Land Use and Land Cover Changes in Europe and the Impact on Near-Surface Wind Speed in Sweden

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Nils Philipp Stange; [2023-08-18]
   Nyckelord :;

   Sammanfattning : Investigations of Land use and land cover change (LULCC) have recently become of increasing interest. This trend occurs not only based of the importance of biogeochemical processes such as carbon sequestration, but also because of their climate impacts caused by changed biogeophysical properties.

3. 2. The Impact of Global Warming on Wind Power Potential in the Greater Horn of Africa

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Bromwel Apondi; [2023-08-17]
   Nyckelord :Near-surface wind speed; the Greater Horn of Africa; ERA5; Wind power density; CORDEX-Africa;

   Sammanfattning : The wind speed variability and wind power potential in the Greater Horn of Africa is analyzed in this study to fill a knowledge gap regarding if wind power can be used more as a source of energy for the region. This is investigated based on reanalysis data from ERA5, observed wind speeds, CORDEX-Africa regional climate models (RCMs) for future projections and a literature review. LÄS MER

4. 3. The atmospheric effects of Southern Ocean open-ocean polynyas onto the coastal polynyas from EC-Earth3

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Jakob Gunnarsson; [2023-05-10]
   Nyckelord :;

   Sammanfattning : Polynyas are recurring areas of open water or thin ice within the sea ice pack, which alter the local oceanatmosphere heat and moisture exchange. They are differentiated as coastal (latent heat) or open-ocean (sensible heat) polynya according to their formation process. LÄS MER

5. 4. ASSESING HISTORICAL (1926-1996) NEAR-SURFACE WIND SPEED VARIABILITY ACROSS SWEDEN

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Jessika Lönn; [2022-06-27]
   Nyckelord :Near-surface wind speed; teleconnection patterns; Sweden; stilling; reversal;

   Sammanfattning : Homogenized near-surface wind speed (NSWS) series of 7 stations from rescued observational journals have been analyzed for the 70-years time-period 1926-1996 to investigate past changes and variations across Sweden. During the whole period, there has been a statistically significant (at p < 0.05) decreasing trend of -0.11 m s-1 decades-1. LÄS MER

7. 5. 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
