  2. 1. Fluxes of Sensible and Latent Heat and Carbon Dioxide in the Marine Atmospheric Boundary Layer

    Author : Erik Sahlée; Ann-Sofi Smedman; Anna Rutgersson; Sören Larsen; Uppsala universitet; []
    Keywords : Meteorology; Sensible heat flux; Latent heat flux; Carbon dioxide; Turbulent exchange; Global heat fluxes; Marine boundary layer; Air-sea interaction; Meteorologi;

    Abstract : Oceans cover about 70% of the earth’s surface. They are the largest source of the atmospheric water vapour and act as enormous heat reservoirs. Thus in order to predict the future weather and climate it is of great importance to understand the processes governing the exchange of water vapour and heat between the ocean and atmosphere.

  4. 2. Radially global neoclassical transport in tokamak pedestals

    Author : Stefan Buller; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tokamak; transport; global effects; collisional transport; fusion; drift-kinetics; plasma physics;

    Abstract : Nuclear fusion has the potential to become a sustainable energy sourcein the foreseeable future. The most developed system for fusion powerproduction is the tokamak, which magnetically confines a plasma at highenough temperature for fusion reactions to take place. READ MORE

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

    Author : Tony Persson; Sven Halldin; Dimitris Melas; Deliang Chen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrology; land-surface processes; heterogeneity; surface fluxes; soil-water content; high latitudes; snow; lakes; climate; mesoscale model; NOPEX; WINTEX; Hydrologi; Hydrology; Hydrologi;

    Abstract : 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. READ MORE

  6. 4. Radiative Heat Transfer in Suspension-Fired Systems

    Author : Adrian Gunnarsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; co-firing; rotary kiln; combustion; Radiative heat transfer; soot volume fraction;

    Abstract : Radiation is the dominating heat transfer mechanism in most furnaces, and the radiative properties of combustion products represent important aspects regarding its suitability as a heat source. However, fuel and energy markets are undergoing rapid changes due to increasing concerns related to the security of supply and increased global warming. READ MORE

  7. 5. Turbulence in the sea ice impacted Southern Ocean and its implications for primary production and carbon export

    Author : Isabelle Giddy; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Southern Ocean; sea ice; submesoscale; diapycnal mixing; heat fluxes; primary production; carbon export; gliders.;

    Abstract : The sea ice impacted Southern Ocean, south of the Antarctic Circumpolar Current, is one of the most important regions on earth for the cycling of carbon and distribution of heat and freshwater around the globe. Here, along-isopycnal upwelling of warm, carbon-rich circumpolar deep water coincides with the annual growth and melt of Antarctic sea ice that represents one of the worlds largest surface water transformations.
