1. 11. ASSESING HISTORICAL (1926-1996) NEAR-SURFACE WIND SPEED VARIABILITY ACROSS SWEDEN

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

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

   Abstract : 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. READ MORE

3. 12. A Statistical Overview of the Spatial Atmospheric Variability Over Isfjorden, Svalbard

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Stenlund Agnes; [2022]
   Keywords : meteorologi; atmosfärsvetenskap; mikroklimat;

   Abstract : The atmospheric spatial variability over Isfjorden, Svalbard, was investigated through statistical data analysis. The data used in the thesis was measured by mobile weather stations installed on three ships crossing the fjord, and two stationary weather stations close to the shoreline, during the autumn of 2021 and spring to autumn 2022.

4. 13. Acoustic Doppler Current Profiling for streamflow measurements in subarctic climate

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Linus Nyström; [2022]
   Keywords : ;

   Abstract : The ADCP (Acoustic Doppler Current Profiling) technology has been widely available and acknowledged as an instrument used for different types of flow measurement since 1990s, from small scale river measurements to larger ocean current mappings. This study was conducted by the author in cooperation with SWECO with the focus on smaller scale measurements especially on small natural watercourses in a sub-arctic climate with the purpose to examine if the ADCP technology can be used as a complement to the more classic methods for this type of flow measurements Current meter and Conductivity flow measurements.

5. 14. Effects of cover crops on nitrous oxide (N2O) emissions in cereal cropping

   University essay from SLU/Dept. of Ecology

   Author : Khadija Aziz; [2022]
   Keywords : cover crops; nitrous oxide; C sequestration; greenhouse gases; off-season emissions; freeze-thaw cycles;

   Abstract : More than 60% of anthropogenic nitrous oxide (N2O) emissions are attributed to agricultural activities. N2O production in soils highly depends on the N availability along with other factors such as soil moisture content, which provide suitable conditions for nitrification and denitrification.

6. 15. Modelling the Effects of Climate Change on Future DOC Export to Lake Mälaren Using a Generalized Watershed Loading Functions (GWLF) Model

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Klara Lindqvist; [2022]
   Keywords : Hydrology; DOC; browning; climate change; drinking water production; Mälaren; Hydrologi; DOC; brunifiering; klimatförändringar; dricksvattenproduktion; Mälaren;

   Abstract : Browning of boreal freshwaters due to an increased export of terrestrial dissolved organic carbon (DOC) has been observed for some decennia. Drivers include recovery from acid deposition and changing climate and land cover. READ MORE
