1. 31. Primary Marine Aerosol Production : An experimental study based on Arctic Ocean water and a sea water proxy

   Författare :Julia Zábori; Margareta Hansson; Gordon McFiggans; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic Ocean; primary marine aerosol; climate change; sea water physical properties; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : This thesis focuses on the interplay between the physical properties of ocean water and primary marine aerosol (PMA) emissions in the context of a rapidly changing Arctic climate. PMAs are an important part of the climate system due to their ability to interact with incoming solar radiation and to influence cloud properties. LÄS MER

3. 32. Fluxes and Mixing Processes in the Marine Atmospheric Boundary Layer

   Författare :Erik Olof Nilsson; Anna Rutgersson; Harm Jonker; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Waves; Growing sea; Swell; Marine boundary layer; Air-sea interaction; Mixing; Momentum flux; Wind stress; Flux attenuation; Sensor separation; Large eddy simulation; Multiresolution analysis; Coupling; Wave model; Climate model; Wave age; Meteorology; Meteorologi;

   Sammanfattning : Atmospheric models are strongly dependent on the turbulent exchange of momentum, sensible heat and moisture (latent heat) at the surface. Oceans cover about 70% of the Earth’s surface and understanding the processes that control air-sea exchange is of great importance in order to predict weather and climate. LÄS MER

4. 33. Entering the dynamic risk space : Assessing planetary boundary interactions through process-based quantifications

   Författare :Arne Tobian; Johan Rockström; Sarah Cornell; Ingo Fetzer; Dieter Gerten; Martin Volk; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Planetary boundaries; climate change; land-use change; Earth system interactions; ecosystem modeling; green water; vetenskap om hållbar utveckling; Sustainability Science;

   Sammanfattning : The planetary boundaries framework is an effort to define a safe operating space for humanity. Its rationale is that sustainable development needs to be achieved in ways that safeguard the stability of the Earth system on which human prosperity relies. LÄS MER

5. 34. Hydro-climatic changes in irrigated world regions

   Författare :Shilpa Muliyil Asokan; Georgia Destouni; Howard Wheater; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; hydro-climatic change; evapotranspiration; irrigation; water demand; water balance; land-use; water-use; hydrological catchment; Aral Sea; India; Mahanadi River Basin; Physical Geography; naturgeografi;

   Sammanfattning : Understanding of hydro-climatic changes in the world’s river basins is required to ensure future food security. Different regional basins experience different levels of hydro-climatic change depending on the endorheic or exorheic nature of a hydrological basin, along with the climatic conditions and human land and water-use practices, for instance for irrigation.

7. 35. Water level management of wetlands in response to current and future RCP climate change scenarios : A mesocosm experiment within climate control chambers

   Författare :Shokoufeh Salimi; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; peatland; constructed wetland; water quality; carbon dioxide emission; ; drought; nutrient release;

   Sammanfattning : Wetlands are integral components of our natural environment since they provide many critical ecosystem services to humanity, such as water purification, climate change mitigation, flood control, and biodiversity. Although wetlands can convey resilience to some degree of changes, they might be vulnerable to climate change. LÄS MER
