  1. 1. Northern Hemispheric Cold Spells and their Tropospheric-Stratospheric Link

    Författare :Kathrin Finke; Abdel Hannachi; Jörg Gumbel; Alexey Karpechko; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Sammanfattning : Cold spells have severe consequences for society. They require early warnings for elaborate mitigation strategies on sub-seasonal to seasonal time-scales. LÄS MER

  2. 2. Wintertime compound extremes in Europe and North America : from dynamics to predictability

    Författare :Richard Leeding; Gabriele Messori; Jacopo Riboldi; Deliang Chen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cold Spells; Climate Extremes; Extratropical Cyclones; North Atlantic; North America; Europe; Meteorologi; Meteorology;

    Sammanfattning : This thesis examines the co-occurrence of wintertime low temperature extremes (cold spells) over North America and wet or windy extremes over Europe. Prolonged (≅ 5 days) North American cold spells can be associated with both upstream and downstream anomalous large-scale atmospheric flows, the latter modulating extreme weather occurrences over Europe.

  4. 4. Extending dynamic vegetation models to simulate range shifts

    Författare :Deborah Zani; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dynamic vegetation model; range shift; migration; paleovegetation;

    Sammanfattning : In response to rapid climate change and increasing human pressure, a wide variety of taxa have shifted their distribution in the past decades (range shift), with important consequences for ecosystem services and human health and economy. However, it is not yet clear whether most species will be able to track their favourable habitats or lag behind the climate signal (migration lag). LÄS MER
