  1. 16. Solar Variability Assessment in the Built Environment : Model Development and Application to Grid Integration

    Författare :David Lingfors; Joakim Widén; Jan Kleissl; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar Variability; Photovoltaics; Grid Integration; Distributed Generation; LiDAR; GIS; Engineering Science; Teknisk fysik;

    Sammanfattning : During the 21st century there has been a rapid increase in grid-connected photovoltaic (PV) capacity globally, due to falling system component prices and introduction of various economic incentives. To a large extent, PV systems are installed on buildings, which means they are widely distributed and located close to the power consumer, in contrast to conventional power plants. LÄS MER

  3. 17. Modelling Freshwater-Seawater Interactions in Coastal Aquifers : Long-term Trends and Temporal Variability Effects

    Författare :Carmen Prieto; KTH; []
    Nyckelord :seawater intrusion; seasonal variability; artificial recharge; spatial and temporal randomness;

    Sammanfattning : Over-exploitation of coastal aquifers causes seawaterintrusion and eventually contamination of groundwater wells inmany parts of the world. Desalination of brackish water andartificial recharge of treated wastewater may then be asustainable strategy for managing groundwater supply inwater-stressed regions. LÄS MER

  4. 18. Spatiotemporal streamflow variability in a boreal landscape : Importance of landscape composition for catchment hydrological functioning

    Författare :Reinert Huseby Karlsen; Jan Seibert; Kevin Bishop; Thomas Grabs; Sarah E. Godsey; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; streamflow; catchment hydrology; boreal; water balance; spatiotemporal variability; landscape analysis; climate change; recession curve; Hydrology; Hydrologi;

    Sammanfattning : The understanding of how different parts of a landscape contribute to streamflow by storing and releasing water has long been a central issue in hydrology. Knowledge about what controls streamflow dynamics across landscapes can further our understanding of how catchments store and release water, facilitate predictions for ungauged catchments, and improve the management of water quality and resources.

  5. 19. Climate, Conflict and Coping Capacity : The Impact of Climate Variability on Organized Violence

    Författare :Nina von Uexkull; Erik Melander; Hanne Fjelde; Jack A. Goldstone; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; civil conflict; communal conflict; climate change; climate variability; Sub-Saharan Africa; Kenya; geo-referenced event data; agricultural dependence; vulnerability; Peace and Conflict Research; Freds- och konfliktforskning;

    Sammanfattning : Understanding the conflict potential of climate variability is critical for assessing and dealing with the societal implications of climate change. Yet, it remains poorly understood under what circumstances – and how – extreme weather events and variation in precipitation patterns affect organized violence. LÄS MER

  7. 20. The atmospheric contribution to Arctic sea-ice variability

    Författare :Marie-Luise Kapsch; Rune G. Graversen; Michael Tjernström; Jennifer Francis; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sea ice; Arctic; Climate Variability; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : The Arctic sea-ice cover plays an important role for the global climate system. Sea ice and the overlying snow cover reflect up to eight times more of the solar radiation than the underlying ocean. Hence, they are important for the global energy budget, and changes in the sea-ice cover can have a large impact on the Arctic climate and beyond. LÄS MER
