  3. 7. Snow-graupel collisions in clouds: a newly derived formulation for breakup of single crystals

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Victor Craig van der Brug; [2022]
    Keywords : Physical Geography and Ecosystem Analysis; Secondary Ice Production; Ice Cloud Number Concentration; Cloud Ice; Ice-Ice Collisions; Snow Crystal; Atmospheric Science Biogeochemical Cycles; Earth and Environmental Sciences;

    Abstract : The observed and well-known discrepancy between concentrations of ice nucleating particles in the environment and the concentrations of ice particles in clouds show that there are additional ‘secondary’ processes enhancing the concentrations of ice particles. In present-day modelling of weather and climate, such processes are mostly overlooked and thus a cause for uncertainty. READ MORE

  4. 8. Evaluating forest wildfire effect on tree increment patterns for boreonemoral forests in Sweden: A pilot study using remote sensing

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Joanna Eaton; [2022]
    Keywords : Physical Geography and Ecosystem analysis; Remote sensing; Sentinel-2A; Forest wildfires; dNBR; NDVI; dNDVI; Dendrochronology; Atmospheric science and biogeochemical cycles; Earth and Environmental Sciences;

    Abstract : The release of anthropogenic greenhouse gases (GHGs) has substantially increased the global mean surface air temperature. Increases in global mean surface air temperature will lead to warmer and drier conditions, promoting more frequent, long-lasting, intense forest wildfires. READ MORE

  5. 9. Vegetation cover change on Tindfjöll mountains, Iceland, assessed by aerial photographs, topography, and climate

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Guðrún Guðjónsdóttir; [2022]
    Keywords : Environmental changes; High Latitudes; Physical Geography; Ecosystem sciences; GIS; Climate Change; Vegetation change; Vegetation cover; Earth and Environmental Sciences;

    Abstract : Guðrún Guðjónsdóttir Climate change is having a great impact on the fragile High Latitude environment where warming is occurring at a rate at least double the global average. It is urgent to understand the relationship between climate and vegetation cover, which is playing an important role, as a carbon sink, for biodiversity, and for protecting against natural hazards.
