  2. 1. Hydrological Modeling for Climate Change Impact Assessment : Transferring Large-Scale Information from Global Climate Models to the Catchment Scale

    Author : Claudia Teutschbein; Jan Seibert; Chris Kilsby; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bias Correction; Climate Change; Climate Models; Ensembles; GCM; HBV; Hydrological Modeling; Precipitation; RCM; Split Sample Test; Streamflow; Sweden; Temperature; Uncertainty; Physical Geography; naturgeografi;

    Abstract : A changing climate can severely perturb regional hydrology and thereby affect human societies and life in general. To assess and simulate such potential hydrological climate change impacts, hydrological models require reliable meteorological variables for current and future climate conditions. READ MORE

  4. 2. On the Late Saalian glaciation : A climate modeling study

    Author : Florence Colleoni; Martin Jakobsson; Johan Nilsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Climate modeling; Eurasian ice sheet; Quaternary; Saalian; surface mass balance; SST; Earth sciences; Geovetenskap; Marine Geoscience; marin geovetenskap;

    Abstract : This thesis focuses on the glaciation of the Late Saalian period (160 -140 ka) over Eurasia. The Quaternary Environment of the Eurasian North (QUEEN) project determined that during this period, the Eurasian ice sheet was substantially larger than during the entire Weichselian cycle and especially that of the Last Glacial Maximum (21 ka, LGM).

  5. 3. Uncertainties in tropical precipitation and radiative feedbacks under climate change

    Author : Alejandro Uribe Cortes; Thorsten Mauritsen; Frida Bender; Caroline Muller; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Climate change; radiative feedback; tropical precipitation; tropical extreme precipitation; climate modeling; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Abstract : Clouds have a significant impact on climate. They contribute to controlling the planetary energy balance, and the precipitation distribution. Global Climate Models (GCMs) designed to reproduce the state of the climate system, however, have difficulties representing clouds. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 5. Climate Related Impacts on a Lake : From Physics to Biology

    Author : Thorsten Blenckner; Rita Adrian; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Ecosystem processes; climate; phytoplankton; NAO; SCI; ice cover; modeling; Biologi; Biology; Biologi; limnologi; Limnology;

    Abstract : Climatic variation and change affect the dynamics of organisms and ecosystem processes. This thesis examines phytoplankton as a target variable to trace climatic impacts on Lake Erken (Sweden) with special emphasis on the spring bloom. READ MORE
