  1. 1. 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

  3. 2. Primary Drivers of Sea Level Variability in the North – Baltic Sea Transition Using Machine Learning

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :David Ek; [2023-01-09]
    Nyckelord :;

    Sammanfattning : Global mean sea level is rising, however not uniformly. Regional deviations of sea surface height (SSH) are common due to local drivers, including surface winds, ocean density stratifications, vertical land- & crustal movements and more. LÄS MER

  4. 3. Evaluation of the ERA5-Land dataset for estimation of soil moisture in the permafrost region

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Alberta van Gent; [2023]
    Nyckelord :Soil moisture; ERA5-Land; International Soil Moisture Network ISMN ; permafrost region;

    Sammanfattning : The permafrost region covers a vast area of land surface on the northern hemisphere,storing large amounts of carbon. Unfortunately, climate warming leads to permafrostthaw altering the hydrothermal state of permafrost soils. Due to the remoteness of thepermafrost region, access to field measurements is restricted.

  5. 4. Mesoscale precipitation systems in the Tibetan Plateau region as represented by global reanalysis, regional downscaling and satellite data between 2001 - 2016

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Benjamin Holmberg; [2022-09-01]
    Nyckelord :Tibetan Plateau; monsoon; westerlies; mesoscale; convection; precipitation; climate modelling; global reanalysis; regional downscaling; spatial resolution; re-initialization; spectral nudging; convective parameterization;

    Sammanfattning : The Tibetan Plateau (TP) is one of the world’s most important water towers. Convective precipitation systems play an important role by providing freshwater for the highly densely populated downstream regions, but they can also cause hazardous floods. LÄS MER

  7. 5. Large-Scale Atmospheric Drivers of Extreme Temperature Anomalies During Springtime in the Arctic

    Kandidat-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Linnea Barreng; [2022]
    Nyckelord :Meteorology; Temperature extremes; Arctic; Jet stream; Rossby waves; Spring; Meteorologi; Arktis; Extremväder; Jetström; Rossbyvågor; Vår;

    Sammanfattning : In this project warm extreme temperature events in the Arctic region during the spring months March, April and May were identified and analysed. In the analysis daily average NCEP reanalysis data from NOAA/OAR/ESRL PSL format was used. LÄS MER
