  1. 1. Extreme Value Analysis of Flooding Related Parameters for Halmstad

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Ruixiao Jin; [2022]
    Nyckelord :extreme value; GEV fitting; Halmstad; return level; seasonal variation;

    Sammanfattning : Floods is a serious concern across Europe due to the enormous material damage and death toll. Of alltypes of floods, flash floods and large-scale river floods have become major natural hydrological hazardsin most countries. LÄS MER

  3. 2. Linking Jet Stream Variability and the NAO to the Terrestrial Carbon Cycle in Europe

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Emma Rosengren; [2020]
    Nyckelord :Terrestrial; Carbon Cycle; Jet Latitude; Jet Speed; NAO; NDVI; Jordbunden; Kolcykel; Jetlatitud; Jethastighet; NAO; NDVI;

    Sammanfattning : The terrestrial carbon cycle is a part of the global carbon cycle, where one important component is the terrestrial vegetation. Terrestrial vegetation largely controls the land surface carbon exchanges and leverage the atmospheric greenhouse gas concentrations, significantly affecting the trajectory of global warming.

  4. 3. NAO Index: An Extreme Pressure Approach

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

    Författare :Patrik Boström; [2014]
    Nyckelord :North Atlantic Oscillation;

    Sammanfattning : The North Atlantic Oscillation (NAO) is the major mode of atmospheric winter variability over the North Atlantic. Its current state has long been described by the station‐based NAO Index. This index has been shown to represent winter temperature anomalies over Northern Europe well. LÄS MER

  5. 4. Evaluation of Long-term Discharge in Swedish Rivers

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Angelica Lidén; Karin Persson; [2012]
    Nyckelord :River Discharge Time Series; Sweden; Wavelet analysis; Northern Hemisphere Teleconnection Patterns and Decadal Oscillation.; Technology and Engineering;

    Sammanfattning : Seasonal forecasting is not an easy task to deal with. A number of large scale atmospheric phenomena, e.g. Northern Atlantic Oscillation (NAO), Scandinavia (SCA) and Pacific Decadal Oscillation (PDO) affect the climate in Sweden and the effect on rivers is an integration of all the complex inter-relation among all these atmospheric phenomena.

    Sammanfattning : The past 51 years northern Europe has experienced nine unusually cold winters, where many temperature records have been set. Two of the three last winters, 2009/10 and 2010/11, were the coldest in many places in southern Sweden since the mid 80’s. LÄS MER
