  1. 1. The cooling potential of Rain Gardens and Green Roofs - The influence on energy partitioning in Kvillebäcken, Gothenburg

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Julia Cederbrant; [2021-07-05]
    Keywords : urban energy balance; urban water balance; SUEWS; energy partitioning; Blue-green infrastructure;

    Abstract : Blue-green infrastructure (BGI) has become a popular way of combating the effects of climate change, both regarding heat mitigation and runoff from precipitation. This thesis aims to understand the potential of two BGI types, namely rain gardens and green roofs, of increasing the latent heat fraction in an urban area and thereby also understand the possible cooling effect from these measures.

  2. 2. Energy balance closure, water balance, carbon exchange, and water use efficiency : observed and modeled outcomes for a managed, hemiboreal forest in Southern Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Linsey Marie Avila; [2019]
    Keywords : Energy balance; energy balance closure; energy balance ratio; net radiation; sensible heat; latent heat; turbulent fluxes; ground heat flux; energy storage; available energy; Bowen ratio; evaporative fraction; latent heat of vaporization; water balance; evapotranspiration; precipitation; water storage; water discharge; gross primary production; ecosystem respiration; net ecosystem production; carbon exchange; water use efficiency; Earth and Environmental Sciences;

    Abstract : The claims for the potential of boreal and sub-boreal forests to combat negative effects of climate change have been substantial with over half of Earth’s primary forests found within boreal and temperate regions of the Northern Hemisphere. Given the likely occurrence of more extreme climate events in the future, ascertaining a better understanding of how climate effects, such as profound fluctuations in precipitation, decreases in yearly snow, faster snow melt rates, variability in evapotranspiration due to environmental stress, and related changes in the energy, hydrological, and carbon cycles will change these northern, boreal landscapes is crucial.

  3. 3. CARBONDIOXIDE FLUXES FROM A CONTROLLED BOREAL RIVER

    University essay from Mittuniversitetet/Avdelningen för ekoteknik och hållbart byggande

    Author : FRANK ARTHUR; [2018]
    Keywords : Carbon dioxide fluxes; Gas transfer Velocity; Turbulence; Eddy covariance; Stream flow; Wind speed; Global Carbon cycle; Latent and sensible heat fluxes.;

    Abstract : River, lakes and   streams account for more carbon dioxide emissions than all other freshwater   reservoirs together. However, there is still lack of knowledge of the   physical processes that control the efficiency of the air-water exchange of   CO2 in these aquatic systems. READ MORE

  4. 4. Sensitivity analysis and calibration of multi energy balance land surface model parameters

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Kim Friberg; [2017]
    Keywords : Physical Geography; Land Surface Model; Multi Energy Balance; Sensitivity Analysis; Parameter Calibration; Earth and Environmental Sciences;

    Abstract : Flows of energy between the atmosphere, the oceans and the land surfaces drive weather and climate on Earth. Increased understanding of these processes is crucial to successfully predict and address the challenges of climate change. READ MORE

  5. 5. Numerical Modelling of Convective Snow Bands in the Baltic Sea Area

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Julia Jeworrek; [2016]
    Keywords : Shallow convection; extreme precipitation; Baltic Sea; SST; regional climate system modelling;

    Abstract : Convective snow bands develop commonly over the open water surface of lakes or seas when cold airgets advected from a continent. Enhanced heat and moisture fluxes from the comparatively warm waterbody trigger shallow convection and an unstable boundary layer builds up. READ MORE
