  1. 1. Spatiotemporal climate and atmospheric circulation variability in Asia inferred from tree rings

    Författare :Andrea Seim; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Asia; atmospheric circulation; Central Asia; dendroclimatology; growth-climate relationship; objectively classified weather types; teleconnections; tree-ring networks;

    Sammanfattning : Observed 20th century warming trends accompanied by more frequent weather extremes such as droughts or intense rainfall events have consequences for societies and environments alike. In Asia, where the majority of the population depend on agricultural productivity, recent climate change is likely to increase societal hardships. LÄS MER

  3. 2. Trees and the environment : Possibilities and challenges in tree-ring research across spatial and temporal scales based on case studies in Sweden

    Författare :Eva Rocha; Steffen Holzkämper; Björn Gunnarson; Anders Moberg; Martin De Luis; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tree rings; Sweden; climate variability; environmental monitoring; ring width; maximum latewood density; stem radial increment; ED-XRF; light rings; Physical Geography; naturgeografi;

    Sammanfattning : The need to understand and quantify the magnitude and frequency of past and current environmental changes increased the demand for high-resolution proxy data across spatial and temporal scales. Due to their long lifespan and global distribution, trees provide a unique and continuous record of environmental variability. LÄS MER
