    Sammanfattning : Particulate matter suspended in air (i.e. aerosol particles) exerts a substantial influence on the climate of our planet and is responsible for causing severe public health problems in many regions across the globe. LÄS MER

  2. 2. 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; Jonas Nycander; Johan Nilsson; Kevin I. C. Oliver; Nathaelle Bouttes-Mauhourat; [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

  3. 3. Hydro-Climatic Variability and Change in Central America Supporting Risk Reduction Through Improved Analyses and Data

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Beatriz Quesada-Montano; Sven Halldin; Hugo G. Hidalgo; Ida K. Westerberg; Fredrik Wetterhall; Denis Hughes; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Central America; climate variability; disaster risk reduction; droughts; drought indices; floods; hydrological model; process constraints; statistical downscaling; uncertainty; ungauged basins; water resources.; Hydrology; Hydrologi;

    Sammanfattning : Floods and droughts are frequent in Central America and cause large social, economic and environmental impacts. A crucial step in disaster risk reduction is to have a good understanding of the causing mechanisms of extreme events and their spatio-temporal characteristics. LÄS MER

  4. 4. Bridging the floods - The role of social learning for resilience building in urban water services

    Detta är en avhandling från Division of Risk Management and Societal Safety, Faculty of Engineering, Lund University

    Författare :Åse Johannessen; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; urban water services; climate change; adaptation; urban transformation; transition; flood risk management; water resources management; disaster risk reduction; resilience; resilient cities;

    Sammanfattning : The development of cities is increasingly threatened by a worldwide water crisis. Urban water services (including drinking water, sanitation and drainage) are facing complex and multiple pressures, which are becoming increasingly frequent and severe. LÄS MER

  5. 5. Evaporation and Heat-flux Aggregation in Heterogeneous Boreal Landscapes

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Tony Persson; Sven Halldin; Dimitris Melas; Deliang Chen; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrology; land-surface processes; heterogeneity; surface fluxes; soil-water content; high latitudes; snow; lakes; climate; mesoscale model; NOPEX; WINTEX; Hydrologi; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Hydrology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Hydrologi;

    Sammanfattning : The boreal forests represent 8 % of all forested areas on the earth and have a significant role in the control of greenhouse gases and an impact on global climate change. The main objective of this thesis is to increase the understanding of how evaporation and heat-flux processes in the boreal forest zone are affecting the regional and global climate. LÄS MER
