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

    University dissertation from Stockholm : Department of Meteorology

    Author : Petter Lind; Erik Kjellström; Michael Tjernström; Jan Erik Haugen; Anna Rutgersson; Abdel Hannachi; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Regional climate modeling; high-resolution; convection parameterization; precipitation; extremes; statistical analysis; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi; meteorologi; Meteorology;

    Abstract : 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. READ MORE

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

    University dissertation from Stockholm : Department of Meteorology, Stockholm University

    Author : Gustav Strandberg; Erik Kjellström; Qiong Zhang; Johan Nilsson; Anders Moberg; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Palaeo climate; climate modelling; proxy data; LGM; MIS 3; meteorologi; Meteorology;

    Abstract : 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). READ MORE

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

    University dissertation from Stockholm : Department of Meteorology, Stockholm University

    Author : Gustav Strandberg; Erik Kjellström; Qiong Zhang; Johan Nilsson; Hans Renssen; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Palaeoclimate; climate model; vegetation; vegetation changes; land-cover; changes; proxy data; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Abstract : 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. READ MORE

  5. 5. On the intra-seasonal to decadal climate variability over South-Asia

    University dissertation from Stockholm : Department of Meteorology, Stockholm University

    Author : Faisal Saeed Syed; Heiner Körnich; Erik Kjellström; Jagadish Shukla; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; South Asia; monsoon; western disturbances; fog; climate variability; climate dynamics; teleconnections; ENSO; NAO; CGT; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : South Asia, a land of contrasting landscapes, seasons and climates, is highly vulnerable to climate variability over intra-seasonal to decadal time scales. In winter, precipitation over the western parts of south Asia and fog over the Indo-Gangetic (IG) plains are the two major climatic features. READ MORE
