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

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

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

    Sammanfattning : 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. LÄS MER

  3. 2. Compound Extreme Wind and Precipitation Events in Europe

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

    Författare :Elisabet Johansson; [2021]
    Nyckelord :compound extremes; North Atlantic Oscillation; extreme precipitation; extreme wind; sammanfallande extremväderhändelser; extrem nederbörd; extrem vind; Nordatlantiska Oscillationen;

    Sammanfattning : The simultaneous occurrences of several extreme events, known as compound extremes, are often associated with greater impact than univariate extremes. Flooding and windstorms are widespread hazards in Europe which can lead to severe property damage and fatalities. LÄS MER

  4. 3. Precipitation variability modulates the terrestrial carbon cycle in Scandinavia

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

    Författare :Ella Ek; [2021]
    Nyckelord :Terrestrial carbon cycle; NDVI; Precipitation variability; EOF analysis; Scandinavia; Terrestra kolcykeln; NDVI; Nederbördsvariation; EOF analys; Skandinavien;

    Sammanfattning : Climate variability and the carbon cycle (C-cycle) are tied together in complex feedback loops and due to these complexities there are still knowledge-gaps of this coupling. However, to make accurate predictions of future climate, profound understanding of the C-cycle and climate variability is essential. LÄS MER

  5. 4. Stand Structure in a Heterogeneous Old-growth Norway Spruce (Picea abies (L.) Karst.) Forest in Northern Sweden

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Sara Jäger; [2020-11-19]
    Nyckelord :;

    Sammanfattning : This study investigate the growth trend in an unmanaged Norway spruce forest in Västerbotten Country, Sweden. The result indicate that relationship between the diameter at breast height (1.3 m) and height follow a statistical significant trendline, where taller trees also represent wider tree diamater.

  7. 5. Klimat och väder i Nordatlanten-regionen under det senaste årtusendet

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Linus Brakebusch; [2020]
    Nyckelord :Solar activity; Volcanic activity; North Atlantic Oscillation NAO ; Medieval Warm Period; Little Ice Age; Earth and Environmental Sciences;

    Sammanfattning : One of the most important areas in climatology today is the development of climate models. To evaluate how well a particular climate model is working it is compared with climate reconstructions based on proxy-data, which is indirect climate information that can be obtained from climate archives.
