  3. 3. Modelling regional climate-vegetation interactions in Europe A palaeo perspective

    Detta är en avhandling från Stockholm : Department of Meteorology, Stockholm University

    Sammanfattning : Studies in paleoclimate are important because they give us knowledge about how the climate system works and puts the current climate change in necessary perspective. By studying (pre)historic periods we increase our knowledge not just about these periods, but also about the processes that are important for climatic variations and changes. LÄS MER

  4. 4. Stormy records from peat bogs in south-west Sweden : implications for regional climatic variability and vegetation changes during the past 6500 years

    Detta är en avhandling från Department of Geology, Lund University

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Holocene climate; south-west Sweden; aeolian activity; humidity changes; vegetation development; REVEALS vegetation modelling; atmospheric circulation changes; peat sediments;

    Sammanfattning : This thesis aims to reconstruct and explain variations in storm activity, humidity, vegetation composition and land cover in south-west Sweden during the past 6500 years. Two ombrotrophic bogs, Store Mosse and Undarsmosse, situated on the coastal plain of Halland, were selected for this purpose. LÄS MER
