  1. 1. Tropical cyclone induced extreme wind, rainfall, and floods in the Mekong River Basin

    Författare :Aifang Chen; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mekong River Basin; Climate extremes; Tropical cyclones; Precipitation; Floods; Satellite data; Reanalysis data;

    Sammanfattning : Increasing magnitude and frequency of climate extremes under global warming are threatening the socioeconomic development in many parts of the world. The Mekong River Basin (MRB) is a good example for how climate extremes can affect society, as the transboundary MRB has experienced hydroclimate changes and fast socioeconomic development during the past decades.

  3. 2. Building a coherent hydro-climatic modelling framework for the data limited Kilombero Valley of Tanzania

    Författare :Alexander Koutsouris; Steve W. Lyon; Jan Seibert; Mekonnen Gebremichael; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Precipitation; Recession analysis; End - member mixing analysis; EMMA; GLUE; HBV; down scaling; Quantile mapping; CFSR; CMORPH; CRU; GPCC; ERA - i; MERRA; TRMM; UDEL; Satellite; Reanalysis; Kilombero; Tanzania; Eastern Africa; Africa; Physical Geography; naturgeografi;

    Sammanfattning : This thesis explores key aspects for synthesizing data across spatiotemporal scales relevant for water resources management in an Eastern Africa context. Specifically, the potential of large scale global precipitation datasets (GPDs) in data limited regions to overcome spatial and temporal data gaps is considered. LÄS MER

  4. 3. The Arctic Summer Atmosphere

    Författare :Cecilia Wesslén; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic; meteorology; reanalysis; clouds; remote sensing;

    Sammanfattning : The Arctic climate has experienced large changes over recent decades, the largest for any region on Earth. To understand the underlying reasons for this climate sensitivity, we need both models and observations. LÄS MER

  5. 4. Modelling Wind Power for Grid Integration Studies

    Författare :Jon Olauson; Mikael Bergkvist; Mats Leijon; Thomas Hamacher; Uppsala universitet; []
    Nyckelord :Wind power; Wind power modelling; Intermittent renewables; Variability; Integration or renewables; Reanalysis data; Power system studies;

    Sammanfattning : When wind power and other intermittent renewable energy (IRE) sources begin to supply a significant part of the load, concerns are often raised about the inherent intermittency and unpredictability of these sources. In order to study the impact from higher IRE penetration levels on the power system, integration studies are regularly performed. LÄS MER

  7. 5. The Emergence of Conditional Subordinators in Swedish : A Study in Grammaticalization

    Författare :Henrik Rosenkvist; tolkning i offentlig sektor och översättning danska och isländska Avdelningen för svenska; []
    Nyckelord :HUMANIORA; HUMANITIES; Scandinavian languages and literature; conditionality; source determination; image schema; abstraction; bleaching; grammaticalization; reanalysis; language change; syntax; Nordiska språk språk och litteratur ; subordinator; conditional;

    Sammanfattning : This thesis is an empirical and theoretical study of the emergence of five Swedish conditional subordinators: utan, om, hvar, ifall and bara. The first changes occur in the 13th century, and the last in the 18th century. LÄS MER
