2. 1. Uncertainties in tropical precipitation and radiative feedbacks under climate change

   Author : Alejandro Uribe Cortes; Thorsten Mauritsen; Frida Bender; Caroline Muller; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Climate change; radiative feedback; tropical precipitation; tropical extreme precipitation; climate modeling; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

   Abstract : Clouds have a significant impact on climate. They contribute to controlling the planetary energy balance, and the precipitation distribution. Global Climate Models (GCMs) designed to reproduce the state of the climate system, however, have difficulties representing clouds. READ MORE

4. 2. Permafrost Groundwater Dynamics : Modeling of vertical and lateral flows in the active layer across multiple scales

   Author : Alexandra Hamm; Andrew Frampton; Peter Kuhry; Jeffrey McKenzie; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; permafrost; climate change; numerical modeling; hydrogeology; groundwater; naturgeografi; Physical Geography;

   Abstract : Hydrological processes in the Arctic are profoundly influenced by the presence of permanently frozen ground, known as permafrost. Conversely, permafrost is greatly affected by hydrological changes resulting from climate change. READ MORE

5. 3. Addressing water scarcity in the Bolivian Altiplano for sustainable water management

   Author : Claudia Canedo Rosso; Avdelningen för Teknisk vattenresurslära; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Climatology; climate modes; Drought; Water balance; ENSO; Soil moisture; crop yield; Remote sensing; Bolivian highlands; arid and semiarid regions; Climate anomaly;

   Abstract : Water scarcity is a consequence of complex interactions between water access and water use. In fact, the time period over which precipitation deficit accumulates is a determing factor for the occurrence of drought. Drought induces crop production losses and far-reaching societal effects. In the South American Altiplano, drought is a major hazard. READ MORE

6. 4. On the intra-seasonal to decadal climate variability over South-Asia

   Author : Faisal Saeed Syed; Heiner Körnich; Erik Kjellström; Jagadish Shukla; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; South Asia; monsoon; western disturbances; fog; climate variability; climate dynamics; teleconnections; ENSO; NAO; CGT; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Abstract : South Asia, a land of contrasting landscapes, seasons and climates, is highly vulnerable to climate variability over intra-seasonal to decadal time scales. In winter, precipitation over the western parts of south Asia and fog over the Indo-Gangetic (IG) plains are the two major climatic features. READ MORE

7. 5. 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
