  4. 12. Atmospheric circulation regimes and climate change

    Author : Jenny Brandefelt; Erland Källén; Jonas Nycander; Vim Verkley; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atmospheric large-scale circulation; greenhouse gas forcing; climate sensitivity; Meteorology; Meteorologi;

    Abstract : The Earth's atmosphere is expected to warm in response to increasing atmospheric concentrations of greenhouse gases (GHG). The response of the Earth's complex and chaotic climate system to the GHG emissions is, however, difficult to assess. In this thesis, two issues of importance for the assessment of this response are studied. READ MORE

  5. 13. Computational fluid dynamics for dispersion calculation in urban surroundings

    Author : Jan Burman; Anna Rutgersson; Sven-Erik Gryning; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CFD; RANS; LES; Toxicological effects; Synthetic boundary conditions; Stable boundary layer.; Meteorologi; Meteorology;

    Abstract : Increased knowledge on dispersion processes in urban environment will enhance the ability in the society to handle events where releases of toxic substances can occur. Also, the ability to increase preparedness at locations where such events potentially can emerge. READ MORE

  7. 15. Transport of mineral dust into the Arctic : Evaluation of two reanalysis datasets of atmospheric composition

    Author : Sebastian Böö; Annica M. L. Ekman; Adam Kristensson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arktis; transport; damm; återanalys; reanalys; aerosol; meteorologi; Meteorology;

    Abstract : The main purpose of this thesis is to examine the mineral dust aerosol transport into the Arctic. Two three-dimensional reanalysis datasets of atmospheric composition, the Copernicus Atmosphere Monitoring Service reanalysis (CAMSRA) and the Modern-Era Retrospective Analysis for Research and Applications, version 2 (MERRA-2), are analyzed with regard to dust transport into the Arctic.
