  2. 1. The Tropospheric Aerosol - Measurements and Modelling. Case studies in Tanzania and Southeast Asia and development of models for size resolved aerosol simulations on the regional scale

    Author : Cecilia Bennet; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aerosol; PM; Source assignment; Chemical Transport Modelling; Model inter-comparison; Sea salt emissions and Aerosol dynamics;

    Abstract : The tropospheric aerosol is a complex constituent of the atmosphere that has impacts on health and the climate. This thesis presents five different studies from Tanzania, Southeast Asia and Europe dealing with urban measurements of particle mass and elemental composition, regional scale modelling of ozone and particle mass of inorganic aerosols and development of modules for sea salt emissions and size resolved aerosol particles with aerosol dynamical mechanisms implemented in a regional scale chemistry and transport model (CTM).

  4. 2. Extreme Storms in the North Atlantic and Europe

    Author : John Hanley; Rodrigo Caballero; Joaquim Pinto; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : A study of the most extreme cyclones affecting the North Atlantic and Europe is presented with particular focus on extreme windstorms over the densely populated area of Western Europe, whose associated high surface wind speeds are capable of causing extensive structural damage and occasionally a loss of life.A novel cyclone identification and tracking algorithm is presented which explicitly recognises ‘multi-centre cyclones’ (MCCs), defined as cyclonic systems which contain two or three sea-level pressure minima.

  5. 3. 231Pa, 230Th and 232Th as tracers of deep water circulation and particle transport : Insights from the Mediterranean Sea and the Arctic Ocean

    Author : Sandra Gdaniec; Carl Magnus Mörth; Matthieu Roy-Barman; Per Andersson; Laura Robinson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protactinium; thorium; Mediterranean Sea; Arctic Ocean; scavenging; marine particles; boundary scavenging; particle transport; geotraces; Marine Geology; maringeologi;

    Abstract : The naturally occurring U and Th-series radionuclides have shown to have a considerable importance for the understanding of biogeochemical processes on Earth and in the ocean. In this thesis, the isotopes 230-thorium (230Th), 232-thorium (232Th) and 231-protactinium (231Pa) are used as tracers of the transport and scavenging of marine particles and water circulation.

  6. 4. Water Condensation and Freezing in the Atmosphere: Exploring Deliquescence and Ice Nucleation

    Author : Dimitri Castarède; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hygroscopicity; Deliquescence; Atmosphere; Particles; Ice Nucleation; Ice Nucleation Chamber;

    Abstract : Atmospheric aerosols play key roles in numerous atmospheric processes. They affect human health, are substrates and components for atmospheric chemistry, and via their contribution to clouds affect the water cycle and the energy balance of the planet. READ MORE
