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

   Detta är en avhandling från Stockholm : Department of Physical Geography and Quaternary Geology, Stockholm University

   Författare :Claudia Teutschbein; Stockholms universitet.; [2013]
   Nyckelord :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; naturgeografi; Physical Geography;

   Sammanfattning : 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. LÄS MER

3. 2. Climate Change: Models, Metrics and Meaning Making

   Detta är en avhandling från Stockholm : Department of Physical Geography and Quaternary Geology, Stockholm University

   Författare :Erik Sterner; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate Science Literacy; Emission Metrics; Knowledge-Behavior Gap; Short-lived Climate Forcers; SF Failure; Integral Theory; Carbon Cycle; Sea Level Rise; Common Pool Resources; Resource Extraction;

   Sammanfattning : This thesis, combining research in climate science and educational science, investigates different aspects of climate knowledge. It consists of five papers and covers three major topics: emission metrics, public understanding of atmospheric CO2 accumulation, and spatial modelling of natural resource use. LÄS MER

4. 3. Model analysis of ocean carbon storage and transport across climate states

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

   Författare :Malin Ödalen; Stockholms universitet.; [2019]
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Oceanography; Climate; Climate model; Carbon cycle; Paleoclimate; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

   Sammanfattning : The ocean carbon cycle plays a fundamental role in the Earth’s climate system, on decadal to multi-millennial timescales. Of the carbon held in the ocean, the atmosphere, and the terrestrial biosphere combined, more than 90% resides in the ocean. Carbon enters the surface ocean through air-sea gas exchange and from terrestrial sources. LÄS MER

5. 4. Reconstruction of Past European Land Cover Based on Fossil Pollen Data : Gaussian Markov Random Field Models for Compositional Data

   Detta är en avhandling från Lund University, Faculty of Science, Centre for Mathematical Sciences, Centre for Environmental and Climate Research

   Författare :Behnaz Pirzamanbein; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2016-11]
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Spatial Statistics; Adaptive Markov Chain Monte Carlo; Dirichlet Observation; Confidence Region; Palaeoecology; Past Human Land Use; Stochastic Partial Differential Equation;

   Sammanfattning : The aim of this thesis is to develop statistical models to reconstruct past land cover composition and human land use based on fossil pollen records over Europe for different time periods over the past 6000 years. Accurate maps of past land cover and human land use are needed when studying the interaction between climate and land surface, and the effects of human land use on past climate. LÄS MER

7. 5. Comfort climate evaluation with thermal manikin methods and computer simulation models

   Detta är en avhandling från Stockholm : Arbetslivsinstitutet och KTH

   Författare :Håkan O. Nilsson; Högskolan i Gävle.; KTH.; [2004]
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Civil engineering and architecture; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur; equivalent temperature; subject; thermal manikin; mannequin; thermal climate assessment; heat loss; office environment; cabin climate; ventilated seat; computer model; CFD; clothing-independent; comfort zone diagram; thermal environment; cabin; climate;

   Sammanfattning : Ökat intresse för energiförbrukning och samtidiga krav på godtagbar termisk miljö gör det nödvändigt att i förväg kunna bedöma personpåverkan från olika kombinationer av klimatfaktorer. Enbart temperaturmätningar tar inte hänsyn till alla klimateffekter på en människa och speciellt inte för lokala effekter av luftrörelser och strålning. LÄS MER
