  1. 1. Kilometer-scale climate modeling of precipitation in the Nordic region

    Författare :Petter Lind; Erik Kjellström; Erik Kolstad; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Convection-permitting climate modeling; Precipitation; Extremes; Atmospheric convection; Nordic region; Climate change; Observations; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Sammanfattning : Future changes in precipitation, in particular extremes, are among the most impact-relevant consequences of a warming climate driven by increases in atmospheric greenhouse gas concentrations. Still, climate model projections of future changes in regional and local precipitation remain uncertain. LÄS MER

  3. 2. On the representation of precipitation in high-resolution regional climate models

    Författare :Petter Lind; Erik Kjellström; Michael Tjernström; Jan Erik Haugen; Anna Rutgersson; Abdel Hannachi; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Regional climate modeling; high-resolution; convection parameterization; precipitation; extremes; statistical analysis; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography; meteorologi; Meteorology;

    Sammanfattning : Weather and climate models applied with sufficiently fine mesh grids to enable a large part of atmospheric deep convection to be explicitly resolved have shown a significantly improved representation of local, short-duration and intense precipitation events compared to coarser scale models. In this thesis, two studies are presented aimed at exploring the dependence of horizontal resolution and of parameterization of convection on the simulation of precipitation. LÄS MER

  5. 4. Samordnad individuell plan (SIP) : Professionellas samt barn och föräldrars erfarenheter

    Författare :Erik Nordström; Sofia Kjellström; Berith Hedberg; Iréne Josephson; Johan Berlin; Jönköping University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Introduktion. Många barn och unga idag har så pass komplexa behov att de behöver samtidiga insatser från olika huvudmän. Insatserna blir alltmer specialiserade och fragmenterade, vilket kräver att professioner inom hälso- och sjukvård, socialtjänst och skola samverkar. LÄS MER

  7. 5. High-resolution simulations of two cold palaeo climates in Europe : MIS 3 and LGM

    Författare :Gustav Strandberg; Erik Kjellström; Qiong Zhang; Johan Nilsson; Anders Moberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Palaeo climate; climate modelling; proxy data; LGM; MIS 3; meteorologi; Meteorology;

    Sammanfattning : The study of past climate is important because it increases our understanding of how the climate system works. Past climate is often reconstructed by using proxies (that is observations of things that tell something about past climate, for example tree rings, pollen in lake sediments and fossils). LÄS MER
