2. 1. Hydrological Seasonal Forecasting

   Author : Kean Foster; Avdelningen för Teknisk vattenresurslära; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrological seasonal forecasting; seasonal forecast; spring flood; multi-model ensembles; teleconnection patterns; modelling chain;

   Abstract : In Sweden, almost half of the electricity produced comes from hydropower. However, the amount of water in the reservoir catchments is not evenly distributed throughout the year. During the colder months, precipitation usually falls as snow and accumulates into a snowpack. READ MORE

4. 2. Seasonality and variability of stratospheric water vapour

   Author : Tongmei Wang; Abdel Hannachi; Qiong Zhang; Alexey Karpechko; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; stratospheric water vapour; seasonality; variability; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Abstract : Stratospheric water vapour (SWV) plays a critical role in the climate system by modulating the radiation budget and influencing the stratospheric chemistry. Studying changes of SWV on global scale is helpful for our understanding of climate change. READ MORE

5. 3. Modelling Freshwater-Seawater Interactions in Coastal Aquifers : Long-term Trends and Temporal Variability Effects

   Author : Carmen Prieto; KTH; []
   Keywords : seawater intrusion; seasonal variability; artificial recharge; spatial and temporal randomness;

   Abstract : Over-exploitation of coastal aquifers causes seawaterintrusion and eventually contamination of groundwater wells inmany parts of the world. Desalination of brackish water andartificial recharge of treated wastewater may then be asustainable strategy for managing groundwater supply inwater-stressed regions. 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. On the Arctic Seasonal Cycle

   Author : Jonas Mortin; Gunilla Svensson; Rune G. Graversen; Wolfgang Dierking; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic climate; Seasonal melt-freeze transitions; Arctic sea ice and snow; Active microwave measurements; Climate model evaluation; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Abstract : The seasonal cycle of snow and sea ice is a fundamental feature of the Arctic climate system. In the Northern Hemisphere, about 55 million km2 of sea ice and snow undergo complete melt and freeze processes every year. READ MORE
